Patent Number: 7,710,474

Title: Luminance signal processing device

Abstract: A filter section performs color carrier component removal and high-frequency level correction according to color image signal data, and a correction section performs edge enhancement correction. By these operations, luminance signal data is obtained. The characteristics of the filter section are established adaptively in accordance with the luminance signal level of low spatial frequency components in the color image signal data, the luminance signal edge level in the color image signal data, whether or not a predetermined color is exhibited in the color image signal data, a color difference edge level in the color image signal data, or whether or not the RGB data reaches the saturation level in the color image signal data.
