Patent ID: 7492951

Claim:
An image processing apparatus connectable via a network to a storage to store an image compressed code of a dynamic image data, comprising: an image expansion unit to expand the image compressed code and to output an expanded image data; a first acquiring unit to acquire information of a master image data stored in a file header of the image compressed code of the dynamic image data stored in the storage; a second acquiring unit to acquire information of the image compressed code of the dynamic image data stored in the storage; a judging unit to judge a picture quality of the expanded image data output from the image expansion unit, the picture quality to be calculated by substituting, into a non-linear function, a ratio of a number of code bits of an entire file of the master image data and a number of code bits of the dynamic image data, and to generate picture quality information, based on the information of the master image data acquired by the first acquiring unit and the information of the image compressed code acquired by the second acquiring unit; and an image display unit to display, on a display unit, an image of the expanded image data output from the image expansion unit and the picture quality information generated by the judging unit, wherein the information of the master image data stored in the file header of the image compressed code is the number of code bits of the entire file of the master image data, and the information of the image compressed code of the dynamic image data is the number of code bits of the dynamic image data.
