Abstract
A false-color suppression method for correcting a pixel value of a target position of an output frame corresponding to a target field is disclosed. The false-color suppression method includes determining whether the target position has motion; determining whether image corresponding to the target position meets a predetermined condition; and if the target position is determined to have motion and the image corresponding to the target position meets the predetermined condition, performing at least one false-color suppression operation to correct the pixel value of the target position of the output frame.
Claims12
A false-color suppression method for correcting a pixel value of a target position of an output frame, the false-color suppression method comprising:
- generating a first motion value corresponding to the target position;
- determining whether the target position has motion;
- generating at least a second motion value, wherein each second motion value corresponds to a reference position of the target position;
- determining a degree of variation between the first motion value and the second motion value;
- and
- if the target position is determined to have motion and the degree of variation is less than a first threshold value, performing a false-color suppression operation to correct the pixel value of the target position of the output frame.
