DIGITAL SIGNAL PROCESSING APPARATUS OF IMAGE SENSOR CAPABLE OF NOISE CANCELLATION AND METHOD FOR NOISE CANCELLATION IN IMAGE SENSOR

摘要

The present invention can increase the degree of integration, while blocking the noise due to interference with the distribution of the effective light power can be reduced with a noise reduction method for providing a digital signal processing apparatus and an image sensor of the image sensor, the present invention To this end, R (Red) G (Green) B (Blue) for receiving a plurality of digital RGB signal providing the kernel for providing RGB to form a kernel; Edge detector for detecting an edge using the plurality of RGB kernel; The RGB interpolation kernel that interpolates the RGB signal being provided from the study; Noise removing for removing a noise component from the interpolated RGB signals with reference to the noise component included in the information output from the edge detector; Color space conversion unit for converting the interpolation and noise removal is complete, the RGB signals to YCbCr signals; Providing YCbCr kernel for providing receiving the YCbCr signal to form a plurality of YCbCr kernel; And provides a digital signal processing apparatus including an image sensor for carrying out the edge emphasis in the edge emphasis YCbCr signal in response to the output of the edge detector. ; In addition, the present invention is a noise of the image sensor provides a removal method.
