Document Type and Number:
Japanese Patent JP5006835
Kind Code:
B2
Abstract:
An error reduction apparatus includes a combing absence detector to detect absence of combing from a luminance signal, a combing presence detector to detect presence of combing from a color-difference signal, a vertical low-pass filter to receive the color-difference signal, and a selector to select one of the color-difference signal and a color-difference signal to which the vertical low-pass filter is applied based on detection results of the combing absence detector and the combing presence detector, and if combing is absent in the luminance signal and combing is present in the color-difference signal, the error reduction apparatus applies the vertical low-pass filter to the color-difference signal and outputs the signal.
