Abstract
The objects of the present invention are to provide an electronic camera which is able to precisely evaluate the type of a subject and perform an optimal gray-scale transformation on the image of the subject. The electronic camera comprises: an histogram creation unit for creating an intensity histogram of an image obtained with an image sensor; and a setting unit for setting a gray-scale transformation characteristic to be applied to the image according to the created intensity histogram. Using the created histogram makes it possible to precisely evaluate the type of the subject and set an optimal gray-scale transformation characteristic.
