Abstract: The present invention relates to an image sensor and to an X-ray system comprising such image sensor. More in particular, the invention relates to an image sensor wherein dose sensing pixels are used in conjunction with artificial pixels to sense a dose of incoming light or radiation. According to the invention, the image sensor comprises one or more shielded photo-sensitive pixels that are shielded for incoming photons and which are each configured for outputting a further reference voltage, wherein the input voltage of the artificial pixels is set in dependence on the outputted further reference voltage(s).

Abstract: An array-based C-MOS sensor device is provided with a facility for on the basis of non-destructive cell readout generating a radiation dose-sensing signal. In particular, the facility is arranged for accessing a subset of multiple distributed C-MOS cells across the array and feeding by such accessed cells an algorithmic means for therein generating an overall feedback dose control signalization and/or an over-all trigger signalization.

Abstract: A system for performing automatic white balance (AWB) control in which the limited white area (200) is clearly defined by a formula which fits exactly to the black body radiator curve (202) in at least two domains, the formula being a function of those two domains. The function is then offset to the left and/or right to define the limited white area (200) around the black body radiator curve (202). No calibration at the time of manufacture is required, and no permanent memory to store respective parameters and measurements for automatic white balancing is necessary. The resultant limited white area (200) can be used provided a color matrix is employed beforehand, in order to transform the color space of the image sensor to a known color space. In this known color space, the exact location of the black body radiator curve is known, and therefore the above-mentioned formula can be used to form the LWA detection region around it.
