IMAGE CAPTURING APPARATUS, CONTROL METHOD FOR THE SAME, AND STORAGE MEDIUM

摘要

An image capturing apparatus comprises an image capturing unit, a memory configured to store the image signal, a writing unit configured to write the image signal to the memory, a readout unit configured to read out at least a partial region of the image signal, a display unit configured to perform live-view display of an image, and a control unit configured to perform control for each frame of the image signal, wherein the control unit sets, when electronic zoom is in operation, the delay time such that the operation of the writing unit writing the image signal to the memory and the operation of the readout unit reading out the image signal from the memory end within a period of one frame of the image signal, regardless of the reading region changing.

1. An image capturing apparatus comprising:
an image capturing unit configured to output, at a predetermined framerate, an image signal obtained by image capture; a memory configured to store the image signal; a writing unit configured to write the image signal to the memory; a readout unit configured to, in a case where a readout region of the image signal written in the memory changes according to electronic zoom, read out at least a partial region of the image signal; a display unit configured to perform live-view display of an image based on the image signal read out by the readout unit; and a control unit configured to perform control, for each frame of the image signal, such that an operation of the readout unit reading out the image signal stored in the memory starts after a fixed delay time from a timing at which an operation of the writing unit writing the image signal to the memory starts, wherein the control unit sets, when electronic zoom is in operation, the delay time such that the operation of the writing unit writing the image signal to the memory and the operation of the readout unit reading out the image signal from the memory end within a period of one frame of the image signal, regardless of the reading region changing.
