Semiconductor device for image distortion correction processing and image reduction processing

A semiconductor device comprising:

• a distortion correction circuit;
• a first memory;
• a filter processing circuit;
• and
• an image reduction circuit,
• wherein the distortion correction circuit performs first distortion correction processing on first image data stored in a second memory to generate first correction image data, and stores the first correction image data in the first memory,
• wherein the filter processing circuit reads the first correction image data from the first memory, and performs first smoothing filter processing on the first correction image data read from the first memory to generate first smoothed image data,
• wherein the image reduction circuit receives the first smoothed image data from the filter processing circuit, and performs first reduction processing on the first smoothed image data received from the filter processing circuit to generate first reduction image data,
• wherein, after the filter processing circuit performs the first smoothing filter processing, the distortion correction circuit performs second distortion correction processing on second image data stored in the second memory to generate second correction image data, and stores the second correction image data in the first memory,
• wherein the filter processing circuit reads the second correction image data from the first memory, and performs second smoothing filter processing on the second correction image data read from the first memory to generate second smoothed image data,
• wherein the image reduction circuit receives the second smoothed image data from the filter processing circuit, and performs second reduction processing on the second smoothed image data received from the filter processing circuit to generate second reduction image data,
• wherein the each of the first and second image data is image data obtained by dividing a captured image, and
• wherein the distortion correction circuit reads the first and second image data from the second memory such that each of the first and second image data has an over lapping region that overlaps with each other.
