| 7420599 | Method and device for the FPN correction of image signals A device for the FPN correction of image signals which are generated by image cells of an image sensor comprises a discriminator for determining in which value range out of at least two value ranges a value of an image signal of an image cell is located at a predete... | 09/02/2008 |
| 7224848 | Method and arrangement for FPN correction in an image signal from an image sensor In order to correct for fixed pattern noise in the signals of an image sensor, image signal values are read out from the pixels of the sensor. Individual correction values are added as analogue quantities to the image signal values via a signal path having a defined... | 05/29/2007 |
| 7126632 | Method and apparatus for modifying the color saturation of electronically acquired images A method for the transformation of image signals that have been obtained by color filtering and have been logarithmically compressed is proposed. The color saturation of the recorded images is increased thereby. According to one aspect of the invention, the transfor... | 10/24/2006 |
