A camera module for electronically recording images has an image sensor with a plurality of image cells. Each image cell provides an electric image signal as a function of the intensity of incident light. Each image cell has a light-sensitive element for generating a light-dependent current, as well as at least one MOS transistor which is arranged in series therewith. The gate of the MOS transistor is at a fixed potential, and the source-drain path is flowed through by the light-dependent current. In accordance with one aspect of the invention, there is arranged at least one light source in the region of the image sensor by means of which the image cells can be illuminated.

Camera module and method for electronically recording images

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 predetermined instant of time. The result determined by the discriminator is feed to a correction device. The correction device selects correction coefficients from a plurality of sets of correction coefficients as a function of the result determined by the discriminator, and a transformation unit calculates the corrected value for the image signal by using the selected correction coefficients.

Method and device for the FPN correction of image signals

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 transfer function. Parameters which are characteristic of the defined transfer function are provided in a memory and the individual correction values are calculated in a correction value calculating unit using the parameters provided.

Method and arrangement for FPN correction in an image signal from an image sensor

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 transformed image signals are determined as a function of the logarithmically compressed image signals and the logarithmically compressed brightness signals for a spectral color.

Method and apparatus for modifying the color saturation of electronically acquired images

A tool device for machining workpieces has a machining tool and at least one sensor oriented toward a machining area of a workpiece to be machined by the machining tool. The at least one sensor senses at least a portion of the machining area and produces sensing signals. At least one processing unit for receiving and processing the sensing signals of the at least one sensor is provided so that an on-line control of the machining process is possible.
