Claim Text:
1. An image sensing device, comprising: a unit pixel including one first sub-pixel of a white color and three second sub-pixels of a color other than the white color in a matrix; a row control block that controls the three second sub-pixels to sequentially output three second sub-pixel signals through a common column line, and controls the first sub-pixel to output a first sub-pixel signal through the common column line, during a read section; an image process block that processes the first and second sub-pixel signals; and a read circuit block that converts one first sub-pixel signal and three second sub-pixel signals, which are selectively transmitted through the common column line from the one first sub-pixel and the three second sub-pixels, to digital signals, respectively, and transmits the digital signals to the image process block, wherein the image process block generates three image data having different exposure times based on the three second sub-pixel signals, wherein the common column line is coupled with the first sub-pixel and the second sub-pixels in common, and wherein the row control block controls one among the three second sub-pixels to have a first exposure time, controls another one among the three second sub-pixels to have a second exposure time which is shorter than the first exposure time, controls the other among the three second sub-pixels to have a third exposure time which is shorter than the second exposure time, and controls the first sub-pixel to have a fourth exposure time which is shorter than the third exposure time, during an exposure section.
