Abstract
An apparatus includes an imaging unit configured to capture an image of a subject formed on a surface having an array of a plurality of pixels, an acceptance unit configured to accept a designation of a pixel or a region including a plurality of pixels on the surface, a determination unit configured to determine an exposure of the pixel or the accepted region to have a predetermined luminance, and to determine an exposure of other pixels or other regions according to a distance from the pixel or the accepted region on the surface, and an output unit configured to output an image signal captured by the imaging unit at the determined exposure.

An apparatus comprising:
- an image sensing element capable of controlling exposure conditions for pixel-groups each of which includes at least one pixel;
- at least one processor;
- and
- a memory coupled to the at least one processor, the memory storing instructions that, when executed by the at least one processor, cause the processor to:
- select a first region including a subject on an image captured by the image sensing element, in response to a user input to an input unit;
- determine the exposure conditions respectively for the pixel-groups so that the first region has a luminance which is different by a predetermined value compared to a luminance of a second region that is not selected;
- determine the exposure conditions respectively for the pixel-groups so that the luminance of the second region becomes lower than a predetermined luminance;
- and
- generate the image captured by the image sensing element at the determined exposure conditions.
