发明名称 IMAGE SENSING APPARATUS AND CONTROL METHOD THEREFOR
摘要 A pixel position corresponding to dust present on an image sensor and its optical system is detected from a dust detection sensed image. It is checked for a normally sensed image obtained by normal image sensing whether each pixel data is data at the pixel position corresponding to dust. Data at the pixel position corresponding to dust undergoes a correction process. An image sensing apparatus capable of suppressing the influence of dust on a sensed image even if dust attaches to the image sensor or its optical system can be realized.
