Abstract

Disclosed are an image sensor and a camera apparatus having the same. The image sensor includes first to fourth color pixel patterns. Each of the first and fourth color pixel patterns includes a plurality of color pixels, and each of the second and third color pixel patterns includes one of a red pixel and a blue pixel. The camera apparatus not only reproduces 3D image data, but also realize high resolution.

First claim

The invention claimed is:

1. An image sensor comprising:
a first color pixel pattern;
a second color pixel pattern;
a third color pixel pattern; and
a fourth color pixel pattern,
wherein each of the first and fourth color pixel patterns comprises a plurality of color pixels,
wherein green information is extracted from the plurality of color pixels,
wherein each of the second and third color pixel patterns comprises one of red and blue pixels, and
wherein red information is extracted from the red pixel and blue information is extracted from the blue pixel.

2. The image sensor of claim 1 , wherein the first to fourth color pixel patterns are arranged as columns in a single row.

3. The image sensor of claim 1 , wherein the second color pixel pattern is different from the third color pixel pattern.

4. The image sensor of claim 1 , wherein two of the plurality of color pixels are green pixels.

5. The image sensor of claim 4 , wherein remaining color pixels comprise at least one of red, blue, and infrared pixels.

6. The image sensor of claim 4 , wherein the plurality of color pixels are arranged in a form of a lattice, and wherein the green pixels are diagonally arranged.

7. The image sensor of claim 1 , wherein the first color pixel pattern is a same as the fourth color pixel pattern.

8. A camera apparatus comprising:
an optical module to receive an optical signal;
an image sensor to detect color information from the optical signal; and
an image processing module to process image data by using the color information, wherein the image sensor comprises a first color pixel pattern, a second color pixel pattern, a third color pixel pattern, and a fourth color pixel pattern,
wherein each of the first and fourth color pixel patterns comprises a plurality of color pixels,
wherein each of the second and third color pixel patterns comprises one of red and blue pixels, and
wherein the image processing module extracts green information from color information detected from the first and fourth color pixel patterns, and extracts red information and blue information from the color information detected from the second and third color pixel patterns.

9. The camera apparatus of claim 8 , wherein the second color pixel pattern is different from the third color pixel pattern.

10. The camera apparatus of claim 8 , wherein two of the plurality of color pixels are green pixels.

11. The camera apparatus of claim 10 , wherein remaining color pixels comprise at least one of red, blue, and infrared pixels.

12. The camera apparatus of claim 10 , wherein the plurality of color pixels are arranged in a form of a lattice, and
wherein the green pixels are diagonally arranged.

13. The camera apparatus of claim 8 , wherein the first color pixel pattern is a same as the fourth color pixel pattern.

14. The camera apparatus of claim 8 , wherein the image processing module extracts a depth map by using color information detected from the first and fourth color pixel patterns.
