In order to implement the low-power design of Gamma correction for image signal processing circuits of CMOS image sensor SoC and ensure the calibration accuracy at the same time,a new gamma correction method is presented.The proposed algorithm combines the look-up table and linear fitting to correct images.To ensure the accuracy,this method uses the look-up table to emend low-value pixels.For high-value pixels,a method of combining look-up table and linear fitting is put forward.When linear fitting,the oute...
