Abstract: An image signal processing device is disclosed, including a sensitivity improvement unit, a Bayer RGB conversion unit, and a color correction unit. The sensitivity improvement unit interpolates input white, red, green, and blue (WRGB) data, mixes a luminance signal of first color space data for the interpolated WRGB data with a first type pixel signal of the interpolated WRGB data to convert the first color space data into second color space data, and converts the second color space data into converted RGB data. The Bayer RGB conversion unit converts color spaces of a second type pixel signal, a third type pixel signal, and a fourth type pixel signal of the interpolated WRGB data to generate the first color space data, and separates the luminance signal and color difference signals from the first color space data. The color correction unit corrects the converted RGB data into output RGB data.
