Image pickup element, image pickup apparatus, and method and program for controlling the same

摘要

An image pickup element generates an AF evaluation value to be used for image-pickup in accordance with an image signal corresponding to a voltage signal obtained from a first pixel group among a plurality of pixels. The image pickup element further outputs an image signal corresponding to a voltage signal obtained from a second pixel group among the plurality of pixels as a live-view display signal for image display. In accordance with the AF evaluation value, a control unit controls a mechanical optical unit having a focus lens and performs live-view display on an image display unit in accordance with the live-view display signal.

主权项

1. An image pickup element for picking up an optical image focused thereon and outputting an image signal corresponding to the optical image, comprising:
a first chip including a plurality of pixels arrayed in a matrix, configured to output an image signal corresponding to the optical image; and a second chip including a control information generation unit and an output unit, wherein the control information generation unit is configured to generate control information to be used for image-pickup in accordance with a first image signal which is obtained from a first pixel group among the plurality of pixels and output the control information in synchronization with a first synchronization signal, and the output unit is configured to output, as an image display signal for image display, a second image signal which is obtained from a second pixel group among the plurality of pixels in synchronization with a second synchronization signal different from the first synchronization signal.
