Please refer to [Camera functions] in [TeliCamAPI Library manual] for more detail.
● Note
The maximum number of frames storable depends on the image size. (maximum 256MByte.)
The number of frames to be transferred by 'ImageBufferRead' command is determined by
'AcquisitionFrameCount'.
Changing 'ImageBufferMode' register value is invalid during image stream data output.
