Abstract
A semiconductor device 1 includes an image input unit 11 and an image output unit 12. The image input unit 11 receives first image data from a camera 91 and outputs second image data to a memory unit 93 through a shared bus 130. The image output unit 12 receives the second image data stored in the memory unit 93 through the shared bus 130 and outputs third image data to a monitor 92. The third image data is generated by performing an affine-conversion on the first image data. Magnification processing in the affine-conversion is not performed in the image input unit 11. In this way, it is possible to provide an excellent semiconductor device suitable for image processing or the like.

1-22. (canceled)
A semiconductor device comprising:
- a data bus;
- an image input unit that receives first image data from an image-taking device and outputs second image data to a storage unit through the data bus;
- and
- an image output unit that receives the second image data stored in the storage unit through the data bus and outputs third image data to an image display device, wherein
- the output third image data is the result of performing an affine-conversion in at least one of the image input unit and the image output unit on data therein, and
- reduction processing in the affine-conversion is performed in the image input unit, but is not performed in the image output unit.
An electronic apparatus comprising:
- an image-taking unit;
- an image input unit that receives first image data output from the image-taking unit;
- a data bus;
- a storage unit that stores second image data output from the image input unit through the data bus;
- an image output unit that receives the second image data stored in the storage unit through the data bus;
- and
- an image display device that receives third image data output from the image output unit, wherein
- the third image data is the result of performing an affine-conversion in at least one of the image input unit and the image output unit, and
- reduction processing in the affine-conversion is performed in the image input unit, but is not performed in the image output unit.
An image processing method comprising:
- (a) a step of obtaining first image data from an image-taking device;
- (b) a step of performing a first affine-conversion for the first image data and thereby generating second image data;
- (c) a step of storing the second image data into a storage unit through a data bus;
- (d) a step of inputting the second image data stored in the storage unit to an image output unit through the data bus;
- (e) a step of performing a second affine-conversion for the second image data and thereby generating third image data;
- and
- (f) a step of outputting the third image data to an image display device, wherein
- the first affine-conversion includes reduction processing and the second affine-conversion does not include reduction processing.
