1. An image sensing apparatus comprising:
- an image sensing section for sensing an image of a subject;
a detector for detecting a luminance of the subject;
a compressor for compressing a dynamic range of the subject image; and
a controller for controlling a compression characteristic to be used in compressing the dynamic range based on a detection result of the detector;
a processor for performing a dodging process concerning the dynamic range compression with respect to the subject image;
a parameter setter for setting a first parameter concerning the dodging process to control the compression characteristic;
a converter for performing a gradation conversion process with respect to the subject image; and
a gradation characteristic setter for setting a gradation conversion characteristic concerning the gradation conversion process, wherein the gradation characteristic setter determines the gradation conversion characteristic based on the first parameter, and the converter performs the gradation conversion process based on the gradation conversion characteristic.
