Abstract:
1. An image processing apparatus comprising: a memory configured to read out and store a partial region image of an image; a calculation unit configured to calculate, for correcting a signal value of an interest pixel of the partial region image, a reference position in the partial region image based on the position of the interest pixel, where the reference position is different from the position of the interest pixel; and a correction unit connected to said memory and configured to calculate the signal value of the interest pixel using signal values of a predetermined number of peripheral pixels centered on the reference position and interpolation coefficients which are multiplied with the signal values of the predetermined number of peripheral pixels; wherein, said correction unit uses a different interpolation coefficients for a case where the predetermined number of peripheral pixels cannot be obtained because the reference position is near the edge of the partial region image and for a case where the predetermined number of peripheral pixels can be obtained.
