The present invention relates to an image warping system capable of quickly performing image warping with low costs by using a cache memory, and a method thereof. The image warping system is provided to generate a transformed image by warping an input image with the help of a cache based WARP engine. The WARP engine accesses the input image and loads a portion of the image to the cache memory for speeding up the engine process. The WARP engine performs interpolation on the input image to generate an output image which is devoid of distortions. The output image obtained is then stored in the DDR of an electronic device.

A multiple camera imaging system comprises a first camera image sensor to obtain a first image of a scene and a second camera image sensor to obtain a second image. The system further comprises an image signal processor (ISP) to produce a first roughly-aligned image from the first image and a second roughly-aligned image from the second image. A feature point in the first roughly-aligned image is identified. A center of a search zone is created, which is a combination of the position of the feature point and an associated disparity value from the first and second roughly-aligned images. The search zone is created within the second roughly-aligned image. Candidate feature points are identified within the search zone, which is much smaller than the entire image. A best-matched feature point pair in the first roughly-aligned image and the second roughly-aligned image is then identified.
