Image capturing apparatus and control method thereof

摘要

An image capturing apparatus determines a scene of a captured image, and, depending on the scene determination result, performs image capture with an expanded dynamic range, or performs a dynamic range contraction process based on the captured image. In the case of executing the dynamic range expansion process, the image capturing apparatus performs image capture at a decreased ISO speed, and performs tone correction for compensating the decrease in ISO speed with respect to the captured image. The image capturing apparatus is thereby capable of performing image capture with a dynamic range that takes into consideration the subject and the scene.

主权项

1. An image capturing apparatus comprising:
a scene determining unit arranged to perform scene determination, based on information regarding a moving image captured prior to the capture of a still image; a gain control unit arranged to control a gain value based on an output from the scene determination unit; and a control unit arranged to control the image capturing apparatus to capture an image, and to selectively execute, based on the output from the scene determination unit, one of (a) a first process for capturing a still image at a decreased gain value, and applying, with respect to a captured still image, tone correction for compensating the decreased gain value, and (b) a second process for capturing a still image, and applying, with respect to a captured still image, tone correction for increasing the brightness of a low luminance portion of the captured still image, based on a characteristic of a high luminance portion of the moving image or the captured still image.
