Integrated circuit photodetectors VERTICAL color separation and a programmable digital processing color signals

摘要

The integrated circuit photodetector vertical color separation and a programmable digital processing color signals, comprising a photodetector array with a color separation, a readout circuit with the analog-digital conversion circuit for digital processing the read signals, characterized in that a digital processing circuit connected in series programmatically configurable blocks up to disable the effect of each of them on the flow of signals: the transmission characteristic correction unit photodetector array, pro programmable piecewise linear transfer function with the set reference displacements and the values ​​of the slope angles in reference grid points of the transfer function for each of the color channels, the replacement block abnormal point deviations photodetector matrix with the assignment threshold anomalous deviation, with the computation of the second derivative in the aperture angles of 3 × 3 points, correction constraints in possible anomalous position points at the corners of the aperture and the correction value central point, correction or recovery unit red component, calculating corrections sharpness and saturation calculating average values ​​of color components in the central aperture of the 3 × 3 points with the reference value geometric displacements red horizontally and vertically with respect to green and blue, additional its offset horizontal forming unit standard in the parameters of three main colors (R, G, B) multiplied with R, G, B components at given by the 3 × 3 matrix, white balance unit and determining AE photodetector matrix multiplication signals on its calculated
