LINLOG technology

LINLOG technology allows the characteristic pixel response to be adapted to the illumination conditions. Every pixel can be programmed on a purely logarithmic, purely linear or any combination of these two curves, a LINLOG response curve.

The transition intensity between the linear and logarithmic response curves can be varied from image to image. It is, however, usually sufficient to make the settings once for each application. The transition between the two response curves is constant and can be constantly differentiated so as to prevent singularities from occurring during image processing.

LINLOG technology offers a large number of benefits compared with the traditional logarithmic response curve: It is not susceptible to "image lag" leading to artefacts with after-images. The use of a linear response curve for low intensities made it possible to considerably improve the contrast. Furthermore, LINLOG technology can be combined with a synchronous shutter (all pixels are exposed simultaneously), which leads to lower gain and offset noise. The principle underlying LINLOG technology is shown in the diagram above. Logarithmic compression at high intensities prevents saturation of the image, even in the event of extremely high in-image contrast.
