Patent ID: 7756331

Claim:
An image processing method for processing input image data from a digital camera having a histogram acquisition unit to acquire histogram information from the input image data, a resizing unit to generate resized image data by resizing the input image data to a predetermined resolution, an encoding unit to generate encoded resized image data by encoding the resized image data, and a recording unit to record the encoded resized image data and histogram information, comprising: an inputting step of inputting the encoded resized image data; a decoding step of decoding the encoded resized image data in said inputting step; an acquiring step of acquiring the histogram information by analyzing the encoded resized image data input from the recording unit; a histogram correction step of correcting the histogram information acquired by said histogram acquisition step; and a display step of displaying the resized image data decoded in said decoding step and the histogram information corrected by said histogram correction step on one screen of a display unit, wherein, when the encoded resized image data has been irreversibly compressed, said histogram correction step corrects the histogram information in accordance with a compression ratio of the encoded resized image data.
