  • Patent number: 8400536
    Abstract: This invention has been made to solve the problem that when a duplicated image is generated by capturing an original image using a digital camera and printing the captured image, lighting unevenness occurs in an image captured under a viewing light source, compared to that under flash light with a predetermined irradiation amount, and accurate color conversion cannot be performed. To solve this problem, pixels exhibiting identical colors are selected from a plurality of positions from the image captured under flash light. The positions of the corresponding pixels are selected from the image captured under the viewing light source. If the color values at the pixel positions differ, the influence of lighting unevenness in the viewing light source exists. Thus, shading correction data for the image captured under a viewing light source is generated so as to remove the shading of the image captured under the viewing light source.
