This is great. I was just about to write my own, as I could not find one on the internet. Planning to write my own application to use a Canon SD110 camera as a webcam. This will save me some work. I started working on it Monday and thought I would just give google one last look, before I spent all weekend on it. If I code in some more functions, I will let you know.

Thanks.

Good timing, as I just recieved a newsletter today that Canon has released an updated SDK!

Effective April 14, 2005, we have begun general distribution of Canon Remote Camera API Software Developers Kit (RC-SDK) Version 8.3 for Windows 98SE/2000/Me/XP and Mac OS 9.x ~ 10.3.x to qualified developers residing in our sales area.
Peter Barrette 05.21.05 / 2pm
Hi Elias,

I compiled and ran your code, but discovered a problem with my camera (S230) when no CF card was present. During the enumeration of volumes on the camera, the errors expected are cdOK and cdENUM_NA. Instead, I was getting an error code of 0xC0000F0 which isn’t listed in either “cderror.h” or “cdConstants.cs”

I did a full writeup on the problem, and my solution at the Canon SDK yahoo group.

One thing I haven’t figured out yet is that the viewfinder display seems to be horizontally reversed for me. The image retrieved to the main form with “Release” is correct, however. A bit odd, but I may just apply a horizontal flip on the image before posting it to the viewfinder if I really get annoyed with it.

Thanks for distributing the wrapper and for your great example app!

Peter Barrette 05.25.05 / 5pm
Hi Elias,

Ok.. I got annoyed with the viewfinder being reversed, so I decided to fix it. In “FormViewFinder.cs” I added the following to the beginning of the “Bitmap Image” set method:
Bitmap bmp = new Bitmap(value);
bmp.RotateFlip(System.Drawing.RotateFlipType.RotateNoneFlipX);

Then I changed this:
this.panelViewFinder.BackgroundImage = value;

To this:
this.panelViewFinder.BackgroundImage = bmp;

Unfortunately, I couldn’t just apply the transformation to “value” and had to create a new bitmap from the passed “value”. Flipping the passed value resulted in the program crashing when stopping the viewfinder. Creating a new bitmap (and flipping it) results in a slightly higher memory usage and slight FPS hit (1 FPS lower for me), but at least the image displays correctly now.

Thanks again,
pb

Any word on a dcraw.c conversion to C#? This was referenced on the original thread but I’ve never heard anything since.

A conversion of that project would enable RAW support for many cameras.

Hope someone has done something that they would like to share.

I’ve made much changes to your API. My version is now much more “.Net compliant”, I made the Camera interface more like other .Net classes. I defined a CameraExceptions, Methods throw exceptions now instead of writing error logs to console. Camera implements IDisposable now. What do you think about creating a sourceforge (sourceforge.net) project for the Canon SDK .Net Wrapper?
Christian Ulrich 07.12.05 / 7am
Hi Andreas,

that would be very nice.
That is exactly what I and many others I belive need.

So go for it

Best regards,
Christian
John Newton 07.13.05 / 5pm
I also am interested in particpating to make the code better. I’m willing to help on a sourceforge project or any forum, for that matter.

I have seen a few mentions of people trying this in VB.NET. I found a great example in which everything works great………except one thing. I am so confused, I was wondering if anyone had any thoughts. The viewfinder on my app (gotten to with the “cameraControl.connect” method, shows what you would see if you looked through the camera’s viewfinder. But the jpg snapped is extremely zoomed. I have tried setting every configuration (zoomPosition, ClipMargin, etc) to nothing but to no avail. No matter which image size I choose, I get a very zoomed image when snapped that does not reflect what I see in the viewfinder (on camera and on app). The code I found I got from here:

http://www.gotdotnet.com/Community/UserSamples/Details.aspx?SampleGuid=167cdf2d-36a1-45db-80a8-3ee5ef1b91c0

In this example it does the same thing (so I didn’t cause this to happen by a faulty copy job).

If anyone has a clue how to fix this, please email me at jslis@bluewatertech.com.

Thanks!
Jenn
John Newton 09.23.05 / 2pm
I had the same problem until I turned off digital zoom — in other words only use optical zoom. The digital zoom isn’t reflected in the viewfinder.

Cosmin Banu 12.15.05 / 7am
Hi, Can anyone tell me if the A610 is supported in the 7.3 SDK (or in any sdk for that matter)? I looked over the list of supported cameras, the A610 is not listed, but A510 is. I need it for my final year project, I need to be able to have my desktop application access the camera through USB cable, take photos on request, and have them transferred one by one after each request. It is for a 3D object scanner. I could have used a webcam, but I need good quality, so since I already have the A610… Also, a high resolution webcam is around $100, which isn’t worth the money. Let me know if the A610 is supported. The project will be done in C# 2.0, so if there’s no 2.0 wrapper at the moment, I think I will start one. Thanks in advance, CB.
Olivier DALET 01.13.06 / 6am
Hi,
I’ve downloaded and used your wrapper, great job!

One word which may be useful for Peter Barrette (see replies)

I’ve fixed (correctly) the reversed image bug:
One shouldn’t try to flip the image in FormViewFinder, but rather in Camera.cs, ViewFinderCallBackFunc : once you have retrieved the BMP, you rotate the image by 180 deg: WRONG! Instead you must apply a vertical flip (RotateFlipType.RotateNoneFlipY) because BMP File format stores its data from bottom to up.

Hope this helps,
Olivier

Are there any plans for a collaborative development? Or is the improved code from Andreas Jerke available anywhere?
Furthermore, did anybody write a wrapper for the new PS-ReC SDK?
Thanks in advance, Marc
Klemens Schwarz 02.08.06 / 1pm
I had a problem while compiling the project: fatal error LNK1181: cannot open input file ‘..\..\..\..\..\cdsdk\lib\CDSDK.lib’.
For this reason the assembly Wrapper.dll can’t be built and therefore the forms project does not work.
Can anybody help me solve this problem?
Thanks! Klemens
Klemens Schwarz 02.08.06 / 2pm
… and when I switch from Debug-mode to Release-mode the compiler says as follows: fatal error C1083: Cannot open include file: ‘cdType.h’: No such file or directory.
Where might be the problem? I can’t find cdType.h either.
Klemens.
Olivier DALET 03.06.06 / 7pm
The 2 files you mention are part of the canon sdk. Obviously they can’t be found by the compiler/linker.
Let’s suppose you’ve installed the canon sdk into c:\foo\csdk, then you have to follow these steps (asserted you are using Visual Studio 2003; if not, just try to find similar options):
1. in the C/C++ tab, under General, you should see on the first line the ‘Additional Include directories’, just modify c:\cdsdk\inc into c:\foo\csdk\inc. This will tell the compiler to also look at header files in this directory (it contains cdType.h)

2. in the solution explorer, select cdsdk.lib and press suppr (the file will be removed from your project). Now if you try to compile, the linker error message should change: it should complain about ‘unresolved externals’. To fix it, you just have to right-click on the project, select Add/Ass existing item, and in the open file dialog, go to c:\foo\csdk\lib, and select cdsdk.lib (mind the default file filters, which should be changed to *.* in order to see the file). Compile, enjoy.

Remarks: be aware of the fact that when you ‘remove’ files from a C++ project, you are just destroying links between your project and existing files that are not deleted. And when you ‘add’ an existing file, you are just creating a link to this file. The file is not moved at all.
This comportment is the strict opposite as the one observed in C# or VB.NET projects (even if you can link a file in a C# project – cf the arrow on the open button) by default.

This remark leads to another one. If you plan to move source code from a machine to another one for instance, be sure to respect the structure of files on the disk. That’s why I would suggest that headers and libraries needed by the C++ wrapper should be copied in the project tree by hand before ‘adding’ them to the project.

i followed your solution but i’ve always the same problem.
i use sdk v7.1 for canon a430

John Anderson 03.09.06 / 7am
apologies in advance but I’m relatively new to both c++ and c# and visual studio 2005 and yet am keen to convert the VS .NET 2003 project to VS .NET 2005. I’ve had quite a painful experience trying to do this so far and was wondering if anyone e.g. previous post ‘thodac’ had made a successful attempt and could make the project available. Thanks for any help.
thodac 03.11.06 / 12pm
i’ve resolved my pb in 2005. it must to modify in function Viewfindercallbackfunction in camera.cs. Replace a line where copy VideoData in bmp.scan0 with function Marshal.copy().
And the pb with cross-thread, it must to add Control.checkallthread..=false in constructor of formviewfinder.

for john anderson : if u want to convert this program in vs2005, you just call the solution file with vs2005, then a convert wizard execute automatically.

I have a program in execute program in winXp/2000. I use VC6 to compile my program using the low version Canon SDK. I found, if I press “execute program” botton in the VC environment, it run well. But if I click the exe file, it will failed when take photo with error “0×0C0000A3″, it puzzle me.
I think it meybe caused by the version problem.So can you send me your Canon SDK 7 version, or 8 version?

You’re all idiots. You need to contact canon for the SDK, it’s not legal to distribute it.
Jenn 08.15.06 / 2pm
This past winter I got a fully working .NET wrapper and built an app in VB.NET that works great. I am using PowerShot A70s. Lately, the cameras have been dropping like flies. It could be because they are 3 years old, but it seems really coincedental that as soon as I switch from a VB6 app to a VB.NET app controlling them they begin to break. It isn’t immediately or the same issue – some work for a few weeks of heavy use with the new app and some break the first few uses with the new app. I have about 7 cameras – all the same age (3 yrs old?). On 1 or 2 the motor that pushes out the lense broke, on 2 or 3 more the photos they took began having this wierd green/purple in the snapped photos. Some have gotten hard to turn on (you keep trying and trying and finally it will power on). Yet the ones that have been being used with the old system (VB6) seem fine. Only the ones being used with the new system seem to be breaking.

My question is this – is it possible the SDK being used with .NET is breaking my cameras? I would think it impossible – I mean, the code doesn’t really do anything but change controls like pushing a button on the camera would do. But not sure what else to think at this point.

I am using SDK6.3 (6.0?) – the reason is because when I tried to switch to SDK7 my camera was no longer supported. I will be upgrading the software soon (since you can no longer buy the A70s) but if the coding can break the cameras I want to know ahead of time so I can plan what to write the new software with the new SDK in.

Anyone else experience anything like this?

orlando 08.22.06 / 5am
i’ve the same problem with unresolved external.

Added mscoree.lib msvcrt.lib msvcmrt.lib to the Linker/Additional Dependencies and now it works.

For the crossthread I’ve added in FormViewer.cs

delegate void SetTextCallback(string text);

void SetText(string text)
{
if (this.InvokeRequired)
{
try
{

this.Invoke(new SetTextCallback(ref this.SetText),
new object[] { text });
}
catch { }
}
else
{
this.labelFramesPerSecond.Text = text;
}
}

and replaced the line in the CalulateFramesPerSecond method
//this.labelFramesPerSecond.Text = avg.ToString() + ” FPs”;
SetText(avg.ToString() + ” FPs”);

In Camera.cs replaced in ViewFinderCallBackFunc
//for (int i=54; i

How many cameras are connected to your application? Have you tried accessing two cameras at the same time? I know it is restricted according to the documentation, but im still asking, just in case.

Hi,

I am using the Canon SDK PR version for the A620.
Do you have any simple examples in c++ that
send the released picture data to a file on the pc?
I have been able to get all the functions working but this one.
I tried following the example demo, but got hopelessly lost in MFC land. The sample at the back of the book is simple, but it does not work. Any help will be appreciated.

I am trying to use the prsdk with the a620 camera.
I can’t get the zoom feature to work with the viewer.
Does anyone have a working sample
bc
Bill 12.08.06 / 11am
I fixed my problem with zooming. Also the code I uploaded has
some errors in it. If anyone wants a working example please
email me at sormozart@aol.com
Matt 12.13.06 / 8am
I had a application with C# 2003 using .Net wrapper which is working perfectly fine. recently I tried to upgrade this application to C# 2005. I have successfully recompile the wrapper with C++ 2005, but when I run the program frames comming to the application very slowly, looks like there is a huge delay. does anyone know how to fix this problem.
Alfred Hung 03.07.07 / 3pm
we got a strange problem with our application.
we using A620 and sdk of CDSDK.
if computer only connect to jcanon A620, there is no problem with our application, we can preview, capture…..

BUT since our application need to connect to another NON-canon camera,
and following errors occurred
———–
PR_StartSDK failed….
300106
PR_GetDeviceList failed: 200061
———-
and then also failed to open camera of course.

what would be solution if we need to load BOTH cameras in one application??

thx,
Alf.
risknfun :: [Camera4K] plan for a real camera 04.02.07 / 7pm
[...] [Camera4K] plan for a real camera ITP/Camera4K 2007/04/02 00:35 Now, it’s time for making the system with a real Canon digital camera. (little bit late…) Simple diagram is like this: Joystick & Buttons -> (wire) -> Remote Controller -> (wireless) -> Camera -> (wire) -> Laptop In the previous prototype, I only used a webcam and a simple program built in processing. But, I noticed that if I use a real camera, I should change many things. Anyway, here are a suitable solution that I researched. Software Part This PSRemote can give me a control of a camera from a Windows PC. But, it seems it has lots of functions so I need some kind of wrapper program which only has very simple functions of it. In addition, I found that there is a Canon Digital Camera Software Developers Kit (SDK). The PSRemote program is also based on this SDK. I sent the request for SDK, but I couldn’t receive response from Canon yet. And, here is a community of a wrapper of Canon SDK written in C#, Canon SDK II. Remote Capture which is a program that enables connection between PC and Camera is available from Canon site. (Download Library > Drivers / Software > RemoteCapture v2.7.5 for Windows ) Remote Controller Part As I mentioned before, I can hack Canon WL-DC100 Wireless Controller to control the camera. It gives me all functions I need such as zoom lens, shoot, and move forward or backward the images in replay mode. Camera Choice Remote Controller above is only available for specific Canon Powershot model such as G1, G2, G3, G5, G6, Pro 1, Pro 90 IS, Pro70, S1 IS, S60, and S70. Remote Capture software supports these models. Considering with the specs and the prices through the Internet(Korean digital camera expert website and market), Canon Powershot G1 is the best option for this project. Shopping List – Canon Powershot G1 (w/ memory, battery, battery charger, and cable) – Canon WL-DC100 Wireless Controller – stores: B&H, Adorama, and J&R Camera4K trackback : comment [...]
Brian F 04.16.07 / 4pm
I’ve been searching for an Image Capture program or the code that still allows me to use the zoom buttons on my camera. Is this just something I have to deal with if i’m using a Canon S2 IS?

Ultimately I just want to have the camera connected to my laptop, have it write the image to the computer, have the image display and write the file name to a DB.
Farhan Tahir 06.19.07 / 6am
Does anybody have SDK of Canon (PS-Rec SDK v1.1.0b) which can work with canon powershot A640. please email me at farhan.tahir@aoserv.com
Adil Abdulhadi 06.23.07 / 6am
I am using SDK V6.1 with VB6. When I run the application at the end user machine I get the live view but when I execute a DoRelaese function I get Error “429: Atcivex can not create object …”

have I missed to copy/register any files?

Your help is very much appreciated.

hi,

I have using same code above you mentioned. All function are working properly.

But I can’t get the image from PR_StartViewer().

Anyone help me, how to display the picture in my window?

Can you find the problem?
Krishnasamy 08.20.07 / 6am
hi bill,

I have one problem for displaying the image. I have retrieved the image from Camera SDK(PR). Only Fullsize image displaying but thumbnail image not display.

call function is:

/* Capture thumbnail */
err = PR_RC_GetReleasedData(
hCamera,
g_ObjectHandle,
prPTP_THUMBNAIL_RELEASED,
1024L,
0,
&MyGetFileDataFunction
);

Callback function:

static ofstream out(“junk.jpg”, ios::out|ios::binary);

switch( pProgress->lMessage )
{
case prMSG_DATA_HEADER:
break;
case prMSG_DATA:
out.seekp((LONG)pProgress->lOffset);
out.write((const char*)pProgress->pbData,pProgress->lLength);
//printf(“Progress = %d\n”, pProgress->lPercentComplete);
break;

case prMSG_TERMINATION:
out.close();

break;
}

What will be problem?

Please Help me.
