Abstract: The method comprises a step of processing pixel values provided at the output of an image sensor comprising a two-dimensional array of pixels including a mix of IR pixels and color pixels. The step of processing includes, for each color pixel, determining a local color-related ratio indicative of a part of infrared light reception in the color pixel, and estimating an infrared portion value from a color pixel value based on the local color-related ratio. The method further includes generating an infrared image from pixel values from the IR pixels and the estimated infrared portion values from the color pixels.

Abstract: The invention concerns a disk-changing unit comprising a tower housing (1) in which is fitted at least one interchangeable disk magazine (13), at least one disk drive (14), if necessary a disk-loading/ejecting drawer (12), a transporting device (17) for moving a disk between the disk magazine (13), the disk drive (14) and if necessary the disk-loading/ejecting drawer (12), an operating device (6) and a computer-controlled control unit (9). To be able to assemble the disk-changing unit individually with the disk magazine (13), the disk drive (14) and if necessary the disk-loading/ejecting drawer (12), the disk magazine (13), the disk drive (14) and the disk-loading/ejecting drawer (12) have the same external dimensions and are modulatively fitted next to each other by being pushed in or pulled out of corresponding recesses (10) and can thus be interchanged, replaced an/or added to.

Abstract: A playback, recording and/or extracting machine for disks designed as information carriers has opposite disk magazines that receive disk-holders or at least one disk in horizontally superimposed disk-receiving compartments and a computer-controlled transport device arranged between the disk magazines and provided with two horizontally movable drawing-out mean for the disk-holders. In order to monitor the driving motor of the transport device and drawing-out means, the driving motor is connected to an incremental signal generator that incrementally detects the position of the driving motor and thus allows the transport device and drawing-out means to be automatically and precisely positioned.

Abstract: A transport device (10) conveys a disc holder (7) with a disc (1) between a disc magazine (4) and another disc magazine (4), between a disc magazine (4) and a running gear (5), or between a disc magazine (4) and a disc loading and issuing slide (11). Two horizontally movable extractor devices (9) on the transport device (10) travel simultaneously in opposite directions crossing each other between a ready position and a transport position. In the ready position, the extractor devices (9) are ready to engage a disc holder (7) from a disc magazine (4). In the transport position, the extractor devices (9) have traveled to their end positions on the transport device (10) and are ready to engage the disc holder (7) to transport the disc holder (7) to another disc magazine (4).
