Image sensing apparatus, image processing apparatus, control method, and computer-readable medium

A method for controlling an image sensing apparatus that has a camera shake correction function of moving an optical axis of an image sensing device, the method comprising:

• an optical axis moving amount acquisition step in which an optical axis moving amount acquisition unit of the image sensing apparatus acquires a moving amount of the optical axis at the time of shooting;
• a dust pixel determination step in which a dust pixel determination unit of the image sensing apparatus scans image data acquired by pre-shooting, during which the camera shake correction function is disabled, and determines a dust pixel corresponding to dust that is adhered to the image sensing device;
• a dust correction data generation step in which a dust correction data generation unit of the image sensing apparatus generates dust correction data based on information about the dust pixel determined in the dust pixel determination step;
• and
• a holding step in which a holding unit of the image sensing apparatus holds the moving amount of the optical axis acquired in the optical axis moving amount acquisition step and the dust correction data generated in the dust correction data generation step,
• wherein the optical axis moving amount acquisition step is a step of acquiring a moving amount that is a difference in position between the optical axis at the time of pre-shooting and the optical axis at the time of ordinary shooting, during which the camera shake correction function is enabled, and
• wherein the holding step is a step of holding the moving amount of the optical axis and image data obtained at the time of ordinary shooting in association with each other.
