Abstract

An image sensor having light-sensitive elements situated in rows and columns, a camera, and a camera system are provided. The image sensor has a repeating pattern including two adjacent rows, the first row having alternating light-sensitive elements having a blue filter and light-sensitive elements having a red filter, and the second row having light-sensitive elements having no blue filters and no red filters, i.e., no color filter.

Claims

1-10. -10. (canceled)

11. An image sensor, comprising:

a plurality of light-sensitive elements including at least one 2×

2 matrix of light-sensitive elements, wherein a light-sensitive element of the first row and the first column of the 2×

2 matrix has a blue filter, and wherein a light-sensitive element of the first row and the second column of the 2×

2 matrix has a red filter, and wherein the two light-sensitive elements of the second row of the 2×

2 matrix have neither a blue filter nor a red filter.

12. The image sensor as recited in claim 11, wherein the two light-sensitive elements of the second row of the 2×

2 matrix have no color filter.

13. The image sensor as recited in claim 11, wherein the image sensor has at least two adjacent rows each having at least four columns, the first row having alternating light-sensitive elements having a blue filter and light-sensitive elements having a red filter, and the second row having light-sensitive elements without blue filters and without red filters.

14. The image sensor as recited in claim 13, wherein the light-sensitive elements of the second row have no color filters.

15. The image sensor as recited in claim 14, wherein the image sensor is a CMOS image sensor.

16. A camera system, comprising:

a lens; and

an image sensor having a plurality of light-sensitive elements including at least one 2×

2 matrix of light-sensitive elements, wherein a light-sensitive element of the first row and the first column of the 2×

2 matrix has a blue filter, and wherein a light-sensitive element of the first row and the second column of the 2×

2 matrix has a red filter, and wherein the two light-sensitive elements of the second row of the 2×

2 matrix have neither a blue filter nor a red filter.

17. The camera system as recited in claim 16, further comprising:

an analyzer unit for analyzing signals from the image sensor.

18. The camera system as recited in claim 17, wherein the analyzer unit is configured to analyze the signals from the image sensor to distinguish between red and white colors.

19. The camera system as recited in claim 18, wherein the analyzer unit is configured to distinguish between red tail lights and white low beams of motor vehicles.

20. The camera system as recited in claim 17, wherein the analyzer unit is configured distinguish between white and yellow colors.
