CAMERA SET-UP AND METHOD FOR ASCERTAINING PICTURE SIGNALS HAVING COLOR VALUES
First Claim
1. A camera set-up, comprising:
- a camera having camera optics, an image sensor for recording an environment and for outputting first image signals, and a color mask applied in front of image sensor; and
an evaluation device, which picks up the first image signals emitted by the image sensor, the image sensor having a plurality of sensor pixels and the color mask having a plurality of filter pixels which are each situated in front of the sensor pixels and include first colored filter pixels and transparent filter pixels;
wherein some of the sensor pixels pick up light via the colored filter pixels and output first color values, and additional sensor pixels pick up light via the transparent filter pixels and emitting intensity values, andwherein the evaluation device ascertains second color values from the intensity values and the first color values of various sensor pixels, and ascertains second image signals from the first color values and the second color values.

Abstract
A method for ascertaining image signals having color values and a camera set-up, which has: a camera having camera optics, an image sensor for recording an environment and for outputting first image signals, and a color mask applied in front of the image sensor, and an evaluation device, which picks up the first image signals emitted by the image sensor, the image sensor having a plurality of sensor pixels and the color mask having a plurality of filter pixels which are each situated in front of the sensor pixels and include first colored filter pixels and transparent filter pixels; and some of the sensor pixels picking up the light via the colored filter pixels and outputting the first color values, and additional sensor pixels picking up the light via the transparent filter pixels and outputting the intensity values. The evaluation device ascertains second color values from the intensity values and the first color values of various sensor pixels, and forms second image signals from the first color values and the second color values.

11. A method for ascertaining image signals having color values, the method comprising:
-
recording an environment using an image sensor, the image sensor having a plurality of sensor pixels, which pick up light via filter pixels having different transmission properties, of which the colored filter pixels let the light over a narrow wavelength range pass through, and the transparent filter pixels let the light over a wide wavelength range pass through which at least partially includes the narrow wavelength range; ascertaining a first image signal, wherein some of the sensor pixels pick up the light via the colored filter pixels and output first color values, and additional sensor pixels pick up the light via the transparent filter pixels and output intensity values; ascertaining second color values from the intensity values and the first color values of various sensor pixels; and ascertaining second image signals using the first color values and the second color values. - View Dependent Claims (12, 13, 14, 15, 16, 17)
