Patent ID: 8503817

Claim:
An image processing apparatus for electrically correcting distortion of an input image to generate an output image, comprising: a correction processing section configured to sequentially read data of the input image for each pixel in an order of inputting, and perform distortion correction for each pixel of the output image using the read data of each pixel of the input image, the correction processing section including: a line memory configured to temporally store data of the input image for a predetermined number of lines, which is a part of the input image; a controller configured to determine whether data of a plurality of input pixels required for generating data of an output pixel is stored in the line memory; and an interpolating section configured to, when determining that the data of the plurality of input pixels required for generating data of the output pixel is stored in the line memory, perform interpolation of the data of the plurality of input pixels to generate data of the output pixel for correcting the distortion, the predetermined number being equal to the number of lines on which a plurality of input pixels which are used for the interpolation to generate the data of one output pixel exist, wherein the correction processing section outputs data of a pixel for which distortion correction is completed in an order different from an order of inputting the data of pixels to the correction processing section based on a predetermined correspondence between pixels of the input image and pixels of the output image.
