Abstract:
1. An image processing apparatus for processing a moving picture photographed by a predetermined photographing device on the basis of access units, comprising: high rate conversion means for executing high rate conversion processing for converting a rate of the access units of the moving picture from a current first rate into a second rate, which is higher than the first rate; detection means for detecting, for each of the plurality of access units forming the moving picture, at least one parameter value representing a characteristic of imaging blur occurring when the photographing device photographs the moving picture; and correction means for correcting, before or after the high rate conversion processing executed by the high rate conversion means, each pixel value forming each subject access unit of the moving picture based on at least one value corresponding to the subject access unit of the parameter values detected by the detection means, wherein, for each of the plurality of access units forming the moving picture, the correction means sets a subject pixel of the pixels forming the subject access unit as a focused pixel, the correction means comprising: filter characteristic conversion means for converting a characteristic of a low-pass filter indicating the imaging blur in accordance with the value corresponding to the focused pixel of said at least one parameter value detected by the detection means; filtering means for applying the low-pass filter whose characteristic is converted by the filter characteristic conversion means to a predetermined block containing the focused pixel of the subject access unit to output a corrected pixel value of the focused pixel as a first value; subtraction means for computing a difference between a pixel value of the focused pixel before being corrected and the first value output from the filtering means to output the resulting difference as a second value; and addition means for adding the second value output from the subtraction means to the pixel value of the focused pixel before being corrected to output a resulting addition value as the pixel value of the focused pixel after being corrected.
