发明名称 Image processing apparatus having an image correction circuit and its processing method
摘要 An image processing apparatus for processing an image sensed by an image sensing element such as a CCD sensor includes a dark correction circuit for making dark correction of the image, a defect correction circuit for correcting a defective pixel in the image using other pixels, and a controller for controlling the shares of dark correction by the dark correction circuit and defect correction by the defect correction circuit on the basis of information which pertains to image sensing such as an ISO speed, temperature, and accumulation time.
