The I/O control block contains a signal input path and a signal output path. 8.1 Input Signal Path The camera has four physical signal input lines, which come from the input opto-isolator of the camera hardware interface (see Section 14.6) and which are fed into the input signal path of the camera.

    12 Pixel Data Processing 12.2 Image Correction 12.2.1 Overview The camera possesses image pre-processing features, that compensate for non-uniformities caused by the sensor, the lens or the illumination. This method of improving the image quality is generally known as ’Shading Correction’ or ’Flat Field Correction’ and consists of a combination of offset correction, gain correction and pixel interpolation.

    12.2 Image Correction The reference images are not stored permanently in flash memory with Correc- tion_SaveToFlash, only the calibration values are stored permanently. PreGain is internally set to 1.0 while setting correction reference images. 12.2.2 Offset Correction The offset correction is based on a black reference image, which is taken at no illumination (e.g.
