Image capturing apparatus capable of reducing time taken to display image on display and method of controlling the same

摘要

An image capturing apparatus comprises a lens array, an image sensor, a display unit, a recording unit configured to record the video data read out from the image sensor, a readout control unit which has a first readout mode of reading out video data of pixels in first regions coinciding with a position relative to each lens and a second readout mode of reading out video data of pixels in second regions, and a control unit configured to perform control, upon reading out video data from the image sensor in the first readout mode, to read out video data from the image sensor in the second readout mode and display a video obtained from the video data read out in the first readout mode, and to record the video data read out in the second readout mode.

1. An image capturing apparatus comprising:
an image sensor having photoelectric conversion elements as pixels and a lens array in which a plurality of lenses are two-dimensionally arrayed in a matrix pattern on the photoelectric conversion elements, which is arranged to make light transmitted through each lens of said lens array be incident on a plurality of pixels; a display unit configured to display video data read out from said image sensor; a recording unit configured to record the video data read out from said image sensor; a readout control unit which has a first readout mode of reading out video data of pixels in first regions coinciding with a position relative to each lens of said lens array from said image sensor and a second readout mode of reading out video data of pixels in second regions other than the first regions from said image sensor; and a control unit configured to perform control, after reading out video data from said image sensor in the first readout mode, to read out video data from said image sensor in the second readout mode and display, on said display unit, a video obtained from the video data read out in the first readout mode, and to record the video data read out in the first and the second readout modes on said recording unit.
