Abstract
When a color image is input, a histogram is generated for each primary color, and a luminance value having the highest frequency is obtained. Next, a luminance value that will become a background candidate is decided in the neighborhood of the luminance value having the highest frequency for each primary color. A value equal to or larger than the decided luminance value is defined to be a background candidate. Additionally, a background color is decided within a background candidate luminance area. By replacing the pixels within the background candidate luminance area with the decided background color, a reverse-side visible portion is removed while maintaining the appearance of the background.
