STILL IMAGE PROCESSING APPARATUS AND QUALITY-IMPROVEMENT METHOD USING CMOS CAMERA

摘要

The image processing method and apparatus improve the image quality of an image taken in a digital CMOS camera is provided.; The image processing apparatus of the CMOS digital camera according to the present invention, an analog-to is characterized in that include a pre-processing for converting the brightness and the color values ​​of the digital image signal output from the digital converting unit. Increase the range of the brightness and color values ​​of the digital image signal through an the pre-treatment by increasing the difference in brightness and color between each pixel is obtained by the relative sharpness and image quality improving effect.; In addition, the image quality enhancement method of the CMOS digital camera according to the present invention, switch the steps of: receiving in a CMOS digital camera input an image of an object and the steps of: generating an electrical signal in accordance with the image of an object, said electrical signal into a digital video signal the method comprising the steps of, characterized by including the step of processing the digital image signal. By increasing the brightness and the brightness between each pixel color values ​​forming the image sikimeuroseo conversion and the color difference of the digital image signals through a histogram equalization algorithm in the step of processing the digital image signal it is increased relative to the sharpness.
