Image capture apparatus and control method thereof

摘要

Evaluation values relating to image capture are detected from at least two out of a plurality of images having different exposure amounts, which are used to generate a composite image. From a plurality of detected evaluation values relating to image capture, an evaluation value relating to image capture used to control an operation of an image capture apparatus is selected under a predetermined operation, thereby improving the detection accuracy of evaluation values relating to image capture in an HDR moving image capture operation.

主权项

1. An image capture apparatus comprising:
an image capture unit including an image sensor that periodically captures a set of images having different exposure amounts; a video signal processor that generates a frame image of an HDR moving image by compositing the set of images having different exposure amounts captured by the image capture unit; an evaluation value detector that detects evaluation values from at least two out of the set of images having different exposure amounts captured by the image capture unit and that selects a greater one of a plurality of evaluation values detected by the evaluation value detector; and a system controller that controls an operation of the image capture apparatus for capturing a next set of images, based on the evaluation value selected by the evaluation value detector.
