The communication between 954 and 953 may have been completed,before Camera turn on.
the camera image signal has not been sent, so the display is a video-free screen.
But what we want is a picture that is displayed as a good image.
Do not let the user see the picture that is not ready yet.
So I want to ask 953 or 954 if there is a scratchpad that can show the status of the "image"
After the signal is ready, the host will display the image.
This way there will be no image state being used to see.
