IPC: H04N1/46
Filed: 2010-03-26
Abstract: PROBLEM TO BE SOLVED: To eliminate color bleeding by correcting the color of color-bleed pixels to the color of surrounding pixels.SOLUTION: Whether a pixel of interest contained in applied image data exhibits color bleed (a false color) is determined. If the pixel of interest is determined to exhibit color bleed, a direction along which luminance is monotonically decreasing in the vicinity of the pixel of interest is discriminated using the pixel of interest as a starting point (YES in step 32, YES in step 33). A search is performed in the direction of monotonically decreasing luminance to find a pixel where the monotonic decrease in luminance ends (step 34). The found pixel where the monotonic decrease in luminance ends is decided upon as a target pixel and a correction value for causing the color of the pixel of interest to match the color of the target pixel is calculated (step 37). The color of the pixel of interest is corrected using the calculated color correction value (step 38).
