Abstract
An image converter includes: a pixel array having multiple imager pixels for outputting imager pixel signals, and a readout and processing device for reading out the pixel array and for receiving and processing the imager pixel signals. The pixel array has multiple reference pixels for outputting reference pixel signals, and at least one reference current device for outputting reference currents to the reference pixels for simulating illumination intensities. The readout and processing is adapted to jointly read out, receive, and process the reference pixel signals and the imager pixel signals.
