Abstract
A method and system for detecting color-crossing error in decoded video signals is presented. The color-crossing error detection method and system detects a color-crossing pattern in a set of corresponding pixels that share a pixel location. Each pixel of the set of corresponding pixels comes from a different field of a set of fields, which includes a current field having a current pixel. The method and system determines that color-crossing error exists at the current pixel when the color-crossing pattern exists for a user configurable number of sequential fields of the same field type at the pixel location.
