Image sensor capable of guranteeing pixel light integration time uniformity and driving method for the same

摘要

PURPOSE: A method for driving an image sensor is provided to solve a problem that brightness in an upper portion of one image differs from that in a lower portion of the image, by generating a signal capable of operating a flash light at an exact time inside a sensor using a line integration method. CONSTITUTION: Whether a flash light supply unit is used is determined. Integration time of every pixel line is checked to use the flash light supply unit until the integration time of the pixel lines is overlapped. A strobe signal is generated while the integration time of every pixel line is overlapped. The flash light supply unit is driven to supply light to all of the pixels.
