Abstract
An apparatus includes a first brightness value acquisition unit configured to obtain a first absolute brightness value by converting a representative brightness value of an image obtained using an image pickup unit, into absolute brightness, a first determination unit configured to determine an output value based on an input-output characteristic of an output device, the output value corresponding to the first absolute brightness value obtained by the first brightness value acquisition unit, and a second determination unit configured to determine information about exposure corresponding to the output value.
Claims20
An apparatus comprising circuitry configured to perform
- first brightness obtaining process to obtain a first absolute brightness value by converting a representative brightness value of an image obtained by capturing an object image, into absolute brightness,
- first determining process to determine an output value based on an input-output characteristic of an output device, the output value corresponding to the first absolute brightness value, and
- second determining process to determine information about exposure corresponding to the determined output value.
A method comprising:
- first brightness obtaining process to obtain a first absolute brightness value by converting a representative brightness value of an image obtained by capturing an object image into absolute brightness;
- first determining process to determine an output value based on an input-output characteristic of an output device configured to output the image, the output value corresponding to the first absolute brightness value;
- and
- second determining process to determine information about exposure corresponding to the output value.
