Abstract
An image data processing apparatus includes a controller which matches a dynamic range of image data to be outputted to an output unit to a dynamic range of data and/or to an output characteristic of the output unit so that the data may be processed in the output unit.
Claims8
An image pickup apparatus comprising:
- (a) image pickup means for forming a plurality of image signals having different exposure conditions;
- (b) combining means for combining said plurality of image signals to form a combined image signal having an extended dynamic range based on a predetermined algorithm;
- and
- (c) recording means for recording said combined image signal and information regarding said algorithm in a predetermined recording medium.
