7.4.3. IdtSvAcquire

[nResult, image] = sharpML (‘IdtSvAcquire’, nCameraId)

Inputs

nCameraId

Specifies a valid camera ID

Outputs

image

Specifies the array where the acquired image is stored

nResult

Specifies the return error code of the function (0 if the function is successful, otherwise not 0)

Remarks

It grabs an image (or two) from the camera. The image grab is synchronous and the function

exits when the frame has been grabbed or a time out occurs. If the camera mode is set to

double exposure, two frames are acquired and the function outputs two image buffers

(arrays), otherwise only the first is valid. The array dimension depends on the image size and

pixel depth: if the pixel depth is 8, the array is an ‘unsigned char’ array; if the pixel depth is

10, the array is an ‘unsigned short’ array.
