Zusammenfassung:The invention relates to the field of image processing, and particularly relates to a method and a device for eliminating image flicker phenomenon. The method comprises the following steps of: respectively processing each row of pixels of one frame of image data output by a sensor, respectively obtaining brightness of each row of pixels in the frame of image data, determining a correction coefficient of each row of pixels according to the brightness of each row of pixels, and finally, correcting the corresponding pixels with each determined correction coefficient. Herein, the correction coefficients are coincident with a sine curve, and the correction coefficients are all obtained based on data of the current frame without reference to the data of the previous frame, thus, the phenomenon of discontinuous brightness adjustment during the correction process is avoided, and the image flicker phenomenon is eliminated in the corrected images.
