Image-displaying device and method for controlling image-displaying device

摘要

An object of the present invention is to reduce display delay time in a live view display. An image capturing device has an image data generation unit that generates image data per line of a display section based on an output of an image capturing sensor in which a start and an end of charge storing are controlled per line, a display control unit that causes the display section to display generated image data sequentially per line, and a control unit that ends charge storing after a first amount of time passes since charge storing of an image capturing target line is started, and starts displaying image data of a display target line corresponding to the image capturing target line after a second amount of time passes since charge storing of an image capturing target line is ended. The second amount of time is time required for starting displaying image data in a display target line after charge storing of an image capturing target line is ended. The control unit starts charge storing of an image capturing target line such that the first amount of time is equal to or less than a vertical synchronization period of the image capturing sensor minus the second amount of time.

1. An image capturing device, comprising:
an image data generation unit that generates image data per line of a display section based on an output of an image capturing sensor in which a start and an end of charge storing are controlled per line; a display control unit that causes the display section to display generated image data sequentially per line; and a control unit that ends charge storing after a first amount of time passes since charge storing of an image capturing target line is started, and starts displaying image data of a display target line corresponding to the image capturing target line after a second amount of time passes since charge storing of an image capturing target line is ended, the second amount of time being time required for starting displaying image data in a display target line after charge storing of an image capturing target line is ended, and the control unit starting charge storing of an image capturing target line such that the first amount of time is equal to or less than a vertical synchronization period of the image capturing sensor minus the second amount of time.
