Claim:
1. An operating method for an image sensing device, comprising: outputting a plurality of control signals having a plurality of selection signals, a plurality of transmission signals and a plurality of reset signals to a pixel unit including a first sub-pixel and a second sub-pixel corresponding to each single color; controlling exposure times of the first and second sub-pixels differently from one another during an exposure time section; controlling a first sub-pixel signal and a second sub-pixel signal respectively outputted from the first and second sub-pixels during a single row line unit time during a read time section; receiving the first and second sub-pixel signals from the pixel unit by an image sensor which generates three or more image data, each of which has different exposure time to one another based on the first and second sub-pixel signals; controlling the first sub-pixel to be exposed for first and second exposure times, and controlling the second sub-pixel to be exposed for third and fourth exposure times during the exposure time section; controlling the first sub-pixel signal exposed for the first exposure time and the second sub-pixel signal exposed for the third exposure time to be outputted during an initial period time of the single row line unit time; controlling a first sub-reset signal and a second sub-reset signal respectively outputted from the first sub-pixel and the second sub-pixel during a medium period time of the single row line unit time; and controlling the first sub-pixel signal exposed for the second exposure time and the second sub-pixel signal exposed for the fourth exposure time to be outputted during a last period time of the single row line unit time, during the read time section, wherein the pixel unit is controlled by the plurality of control signals having the plurality of selection signals, the plurality of transmission signals and the plurality of reset signals.
