  • Camera capable of canceling noise in image data and signal processing method thereof
    Patent number: 6747696
    Abstract: In a camera having a gamma-correction circuit on an output signal processing path of a CCD, an incident light path leading to the CCD is kept opening in a state where nonlinear gamma-correction processing in the gamma-correction processing circuit is prohibited, first image data (CCD output data; DATA1) are generated based on electric signal output from the CCD, incident light path leading to the CCD is kept closing, second image data (CCD output data; DATA2) are generated based on electric signal output from the CCD and lastly, the second image data DATA2 are subtracted from the first image data DATA1, thereby correcting to eliminate dark voltage component included in the first image data DATA1.
