ABSTRACT:
To enable the recording of a high-quality motion image and enable the recording of a still image which is focused with high precision even when the still image is recorded during the recording of the motion image, a mixed image signal obtained by mixing image signals in a one-to-one correspondence with individual pixels is outputted from an image sensor when a specified operation for starting the recording of the motion image is performed so that relatively high-speed automatic focusing is performed based on the mixed image signal and a high-quality motion image is recorded. When a shutter switch is half-pressed, a thinned image signal for an image from which pixels in vertical directions have been thinned out is outputted from the image sensor so that relatively high-precision and high-speed automatic focusing is performed based on the thinned image signal. When the shutter switch is full-pressed, image signals for all the pixels are outputted from the image sensor so that a still image is recorded.
