Anti-flicker camera and image capture method thereof
Anti-flicker camera and image capture method are disclosed. According to the disclosed method, exposure integrals of different lines of an image sensed by a camera device are calculated. The exposure integrals are compared with reference exposure integrals of the plurality of lines, respectively, to calculate exposure integral offsets for the lines. The reference exposure integrals are estimated from at least one reference image. The positive and negative changes of the exposure integral offsets are statistically analyzed and, accordingly, it is determined whether there is light flicker from background illumination and an auto-exposure control module of the camera device is controlled based on the determination.
