Image capturing apparatus and method for controlling the same

摘要

In an image capturing apparatus, a generation unit performs image processing to generate a synchronizing signal for an image sensor, an image generation unit generates image data using an electric signal obtained from the image sensor, and a display control unit reads out the image data stored in a storage unit and displays it on a display unit. The generation unit controls a phase of the synchronizing signal such that the display processing starts when the image processing for a predetermined volume of image data is finished if a frame period (first period) of the image sensor is shorter than a frame period (second period) of the display control unit, and that a predetermined volume of unprocessed image data is left in the storage unit when the image processing for one frame is finished if the first period is not shorter than the second period.

1. An image capturing apparatus comprising:
an image sensor configured to convert received light into an electric signal; a generation unit configured to generate a synchronizing signal for driving the image sensor; an image generation unit configured to perform image processing for generating image data using the electric signal obtained from the image sensor; a storage unit configured to store the image data; a display unit; and a display control unit configured to perform display processing for reading out the image data stored in the storage unit and displaying the image data on the display unit, wherein the generation unit controls a phase of the synchronizing signal for the image sensor by regarding a start of the display processing by the display control unit as a synchronizing reference such that the display processing is started at a timing of the image generation unit performing the image processing on a predetermined volume of image data, in a case where a first period that is a frame period of the image sensor is shorter than a second period that is a frame period of the display control unit, and controls the phase of the synchronizing signal for the image sensor by regarding completion of the display processing for one frame as the synchronizing reference such that a predetermined volume of image data that has not been processed by the display control unit is left in the storage unit when the image processing for one frame is finished by the image generation unit, in a case where the first period is longer than or equal to the second period.
