What does BU camera do on frame loss? Any function to compensate that?（No.1549）
Frame loss is a phenomenon that an application failed to get some frames in a series of frames sent from a camera. Application can detect frame loss by checking BlockID of received frame.
BU/DU camera does not have any event or call back to notify frame loss.
Refer to attached "FAQV4_2_DetectFrameLost.pdf" about how to detect rame loss.
In order to avoid frame loss, CMOS type camera has image buffer (64M byte) function. This function store the image data from sensor to memory space in camera after exposure is completed
CCD type camera does not have this function, however, there is almost no frame loss as data amount to transfer is small.
In case of camera with image buffer function, data is stored in memory space and transferred from the memory. Therefore, the next transfer will start only after the current transfer will be completed. All the frames can be surely transferred with image buffer. (As an exception, new data will be disposed when image buffer itself is overflow.)
