US Patent 7787019 Camera and shooting control method therefor

Disclosed is a camera which analyzes an image signal output periodically from an image pickup device to determine a timing suitable for shooting a still image, and acquires an image signal for a still image having a larger number of pixels based on the determination result. The suitable timing can be determined by using a moment of, for example, a change in the moving direction of a moving subject, a pausing of a moving subject, or a change in a voice to be input. The image signal for a still image can stay recorded only when a camera user gives an instruction to shoot a still image within a predetermined period from the determination.
