Image capturing apparatus, control method, and program thereof

摘要

An image capturing apparatus includes an image capturing unit which captures an image of an object and outputs an image, a switching unit which switches modes between a first mode in which the image capturing unit outputs a first image and then outputs a second image having an exposure value different from the first image, and a second mode in which the image capturing unit continuously outputs an image not used for compositing, an exposure control unit which controls an exposure value for capturing an image of an object, following change in object luminance, when a parameter related to change in object luminance exceeds a predetermined range in which an exposure value for capturing an image of the object is not controlled to follow the change in object luminance, and a setting unit which sets the predetermined range.

1. An image capturing apparatus having a processor executing instructions stored in a memory and an image capturing unit configured to capture an image of an object and to output an image, wherein the instructions comprise:
a switching unit configured to switch modes between a first mode in which the image capturing unit outputs a first image and then outputs a second image having an exposure value different from the first image, and a second mode in which the image capturing unit continuously outputs an image not used for compositing; an exposure control unit configured to control an exposure value for capturing an image of an object, following change in object luminance, when a parameter related to change in object luminance exceeds a predetermined range; and a setting unit configured to set the predetermined range, wherein the first image and the second image are used for compositing, wherein the predetermined range is a range in which an exposure value is not controlled to follow the change in the object luminance for capturing an image of the object, wherein the setting unit sets a first range as the predetermined range in the first mode, and wherein the setting unit sets a second range which is narrower than the first range as the predetermined range in the second mode.
