Abstract
A semiconductor device includes a distortion correction unit that performs correct distortion processing on a captured image, a SRAM that stores image data after the distortion correction processing, a filter processing unit that receives the image data after the distortion correction processing from the SRAM and that performs smoothing filter processing on the image data after the distortion correction processing, after the image data after the distortion correction processing having a size required for the smoothing filter processing is stored in the SRAM, and an image reduction unit that performs reduction processing on image data after the smoothing filter processing.
Claims12
A semiconductor device comprising:
- a distortion correction unit that performs correct distortion processing on a captured image;
- a Static Random Access Memory (SRAM) that stores image data after the distortion correction processing;
- a filter processing unit that receives the image data after the distortion correction processing from the SRAM and that performs smoothing filter processing on the image data after the distortion correction processing, after the image data after the distortion correction processing having a size required for the smoothing filter processing is stored in the SRAM;
- and
- an image reduction unit that performs reduction processing on image data after the smoothing filter processing.
An image processing method of a semiconductor device that is configured by a single semiconductor substrate that provides a Static Random Access Memory (SRAM), the image processing method comprising:
- performing distortion correction processing on the captured image;
- storing in the SRAM image data after the distortion correction processing having a size required for smoothing filter processing;
- reading from the SRAM the image data after the distortion correction processing having the size required for the smoothing filter processing;
- performing the smoothing filter processing on the image data after the distortion correction processing read from the SRAM;
- and
- performing reduction processing on image data after the smoothing filter processing.
