Patent ID: 8125537

Claim:
An image processing method for performing image processing on captured image data obtained through an imaging lens of an imaging apparatus, the method comprising the steps of: preparing a look-up table that stores addresses of the captured image data corresponding to addresses of an output image data at intervals of an integer ‘a’ in a horizontal scanning direction and at intervals of an integer ‘b’ in a vertical scanning direction, the horizontal scanning direction being an x-direction and the vertical scanning direction being a y-direction; at least one of calculating the addresses of the captured image data corresponding to the addresses of the output image data from the look-up table if the addresses of the captured image data corresponding to the addresses of the output image data exist in the look-up table and calculating the addresses of the captured image data in a first interpolation process if the addresses of the captured image data corresponding to the addresses of the output image data do not exist in the look-up table; and generating image data corresponding to the addresses of the output image data in a second interpolation process based on the captured image data by using at least one of the calculated addresses of the captured image data and the addresses of the captured image data in the look-up table, the generated image data being the output image data.
