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 pick up of an optical image focused thereon and outputting an image signal corresponding to the optical image, comprising:
a first element unit comprising a plurality of pixels arrayed in a matrix, configured to output a voltage signal corresponding to the optical image; and a second element unit configured to convert the voltage signal into a digital signal to obtain the image signal, wherein the second element unit comprises: a control information generation unit configured to generate control information to be used for image-pickup in accordance with a first image signal which is an image signal obtained from a first pixel group among the plurality of pixels; and an output unit configured to output, as an image display signal for image display, a second image signal which is an image signal obtained from a second pixel group among the plurality of pixels.
