Digital still camera and image correction method

摘要

To be capable of correcting a captured image to an image desirable to a user only by using a digital still camera. An RAM 15 storing the image data of an image for which tone correction is to be performed in a standard color space format and a tone correction circuit 35 are provided. The image data is read out from the RAM 15 , and the tone correction is performed for the readout image data in the tone correction circuit 35 . In automatic tone correction, luminance signals of the image are statistically analyzed to categorize the image, and an appropriate correction curve is used to correct the image.
