Abstract

The display system includes a display system including an image-capturing apparatus including an image-capturing element; an image processing apparatus that performs image processing on the image; and a display apparatus including a display device that displays the image resulting from the image processing. The image processing apparatus includes an image processor that performs the image processing on a predetermined number of line images corresponding to a part of a frame image captured by the image-capturing element, sequentially outputs the image to the display apparatus per the predetermined number of line images, and causes the display apparatus to display the frame image; and a storage device that stores the predetermined number of line images until the frame image is completed. The image processor is configured to perform the image processing including frame unit processing on the predetermined number of line images associated with the frame image to be output.

First claim

What is claimed is:

1. A display system comprising:
a display apparatus that displays an image resulting from image processing, the display apparatus including a plurality of pixels arranged in a matrix of a row direction and a column direction;
an image-capturing apparatus including an image-capturing element that captures an image including a part of a frame image that corresponds a predetermined number of line images that is output by the pixels arranged in the predetermined number of rows; and
an image processing apparatus that performs the image processing on the image, including:
a storage device that stores the predetermined number of line images until the frame image is completed to store line images of a completed frame image; and
an image processor that is configured to

perform frame unit processing on a on the predetermined number of line images corresponding to the part of the frame image based on the line images of the completed frame image, and
sequentially outputs the image per the predetermined number of line images by the pixels arranged in the predetermined number of rows to cause the display apparatus to display the frame image.

2. The display system according to claim 1 ,
wherein the image processor is configured to perform, on the predetermined number of line images, the frame unit processing using a frame image one or more frames before a frame image made up of the line images.

3. The display system according to claim 2 ,
wherein the image processor is configured to perform the image processing including line unit processing on the predetermined number of line images to be output to the display apparatus.

4. The display system according to claim 3 ,
wherein the line unit processing includes one or more of gradation correction and color correction.

5. The display system according to claim 1 ,
wherein the image processor is configured to perform the image processing including line unit processing on the predetermined number of line images to be output to the display apparatus.

6. The display system according to claim 5 ,
wherein the line unit processing includes one or more of gradation correction and color correction.

7. The display system according to claim 1 ,
wherein the frame unit processing includes one or more of distortion correction, auto exposure, and auto white balance of the image.

8. The display system according to claim 1 , further comprising a coupler used to transmit data between the image-capturing apparatus and the image processing apparatus, between the image processing apparatus and the display apparatus, or both.

9. The display system according to claim 8 ,
wherein the coupler is provided between the image-capturing apparatus and the image processing apparatus, and is configured to transmit data of the line images yet to be subjected to Bayer conversion, and
wherein the image processing apparatus performs pixel interpolation on the line images yet to be subjected to Bayer conversion.

10. The display system according to claim 9 ,
wherein the image-capturing apparatus and the display apparatus are configured to operate in association with a vehicle, and
wherein the image-capturing apparatus is configured to capture an image outside the vehicle.

11. The display system according to claim 10 ,
wherein the display system comprises a plurality of the image-capturing apparatuses, and
wherein the image processor is configured to synthesize images captured by the image-capturing apparatuses.

12. The display system according to claim 10 ,
wherein the display system comprises a plurality of the display apparatuses, and
wherein, when at least one of the display apparatuses is not operable, at least one of the display apparatuses is operable and configured to display and output data as a substitute for the display apparatus that is not operable.

13. The display system according to claim 12 ,
wherein the display system comprises a plurality of the image-capturing apparatuses, and
wherein the image processor is configured to synthesize images captured by the image-capturing apparatuses.

14. The display system according to claim 8 ,
wherein the image-capturing apparatus and the display apparatus are configured to operate in association with a vehicle, and
wherein the image-capturing apparatus is configured to capture an image outside the vehicle.

15. The display system according to claim 8 ,
wherein the coupler includes a least one of a serializer, a deserializer and a signal line.

16. The display system according to claim 1 ,
wherein the image-capturing apparatus includes at least three image-capturing elements.

17. A display apparatus comprising:
a storage device that stores a predetermined number of line images until a frame image is completed to store line images of a completed frame image; and
an image processor that is configured to
perform frame unit processing on the predetermined number of line images corresponding to a part of a frame image captured by an image-capturing element based on the line images of the completed frame image, and
sequentially outputs an image per the predetermined number of line images by a plurality of pixels arranged in the predetermined number of rows to display the frame image.

18. A display system comprising:
a display apparatus that displays an image resulting from image processing, the display apparatus including a plurality of pixels arranged in a matrix of a row direction and a column direction;
an image-capturing apparatus including an image-capturing element that captures an image including a part of a frame image that corresponds a predetermined number of line images that is output by the pixels arranged in the predetermined number of rows; and
an image processing apparatus that performs image processing on the image,
wherein the image-capturing apparatus, the display apparatus, and the processing apparatus are configured to operate in association with a vehicle,
wherein the image processing apparatus is arranged near one of the image-capturing apparatus and the display apparatus,
wherein the image processing apparatus includes an image processor that performs is configured to
perform frame unit processing on the predetermined number of line images corresponding to the part of the frame image based on the line images of the frame image, and
sequentially outputs the image per the predetermined number of line images by the pixels arranged in the predetermined number of rows to cause the display apparatus to display the frame image.

19. A display system comprising:
