ABSTRACT:
A digital camera has a CPU and an image processing apparatus. The image processing apparatus acquires a contour from an image acquired by shooting a whiteboard as a shooting target by using a Roberts filter. The image processing apparatus detects straight lines to be candidates which form the image of the whiteboard from the acquired contour, and acquires the rectangular shape of the whiteboard. The image processing apparatus acquires projection parameters indicating the relationship between the image of the whiteboard and the real whiteboard from vertex positions of the quadrangle, and performs projection transformation of the image of the whiteboard.
