Abstract:
1. An image processing device, comprising: a data conversion process unit performing pixel conversion by interpreting a two-dimensional RGBW pixel arrangement signal in which pixels which are main components of a brightness signal are arranged in a checkered state, and pixels of a plurality of colors which are color information components are arranged in the remaining region, wherein the data conversion process unit includes a parameter calculation unit calculating a parameter which is applied to a pixel conversion process by interpreting the two-dimensional RGBW pixel arrangement signal and the parameter calculation process unit performs a calculation process of calculating the parameter using at least of one of first correlation information for a correlation between the pixel which is the main component of the brightness signal included in the two-dimensional pixel RGBW arrangement signal and the color information component of the pixel after conversion, and second correlation information for a correlation between one color information component selected from among the color information components and the color information component of the pixel after the conversion, in the calculation process of the parameters which are applied to the pixel conversion process; wherein the parameter calculation unit selects which one of first correlation information on a correlation between a white (W) pixel configuring the RGBW pixel arrangement signal and the color information component of the pixel after the conversion and second correlation information on a correlation between a green (G) pixel configuring the RGBW arrangement and the color information component of the pixel after the conversion is used, according to 4 kinds of edge directions, longitudinal, traverse, left gradient upward, and right gradient upward, which an edge detection unit detects.
