Solid-state image-pickup device, method of driving solid-state image-pickup device and image-pickup apparatus

摘要

A solid-state image-pickup device includes a pixel array unit including pixels that include photoelectric transducer two-dimensionally arranged in a matrix and a driving unit for reading out pixel information corresponding to a number of pixels less than the number of pixels included in the pixel array unit as monitoring image information and reading out pixel information corresponding to a predetermined region in the pixel array unit at a cycle shorter than the display cycle of the monitoring image as autofocus image information.
