Abstract: The photographing apparatus includes an image pickup unit that generates a raw image; a feature extractor that extracts a feature image containing at least one feature part from the raw image; an image processor that performs image processing of the raw image according to a first scene information and that performs image processing of the feature image according to a second scene information; a quantizer that performs discrete cosine transform and quantization of a raw-processed image obtained by performing image processing of the raw image and a feature-processed image obtained by performing image processing of the feature image; a difference data generator that generates difference data indicating a difference between image data obtained by processing the raw-processed image in the quantizer and feature image data obtained by processing the feature-processed image in the quantizer on a feature image data basis; and an image compressor.

Abstract: An image capturing device and method for improving capturing skill or knowledge by enabling a user to understand a reason for setting a proper capturing parameter. The image capturing device switches between an auto capturing mode for automatically setting capturing conditions and a manual capturing mode for manually setting capturing conditions, and includes a capturing parameter setting part that sets a capturing parameter used in the auto capturing mode, based on parameter determination information calculated from an original image, a setting reason setting part that associates and stores a setting reason for the capturing parameter value with a value of the parameter determination information corresponding to the capturing parameter, and an association processing part that determines the setting reason from the capturing parameter value in the auto capturing mode by referring to the setting reason storing part, and associating the setting reason with a captured image.
