发明名称 Noise reduction device and method using a shaded image in an electronic camera
摘要 The noise reduction device includes an image storage unit, a blackout image processing unit, and a noise processing unit. The image storage unit captures image data obtained by imaging a field with an image sensor, and stores the image data therein. The blackout image processing unit captures blackout image data obtained by imaging by the image sensor that is shaded, and extracts a specific noise component of the blackout image data. The noise processing unit reduces a noise in the image data based on the specific noise component of the blackout image data.
