PHOTO-RECEIVING CELL WITH VERTICAL COLOUR SEPARATION Russian patent published in 2009 - IPC G02F1/00 

FIELD: instrumentation.

SUBSTANCE: invention relates to computer vision and can be used in video cameras and HR cameras. In compliance with the invention, photo receiving cell comprises readout circuit, red, green and blue component detectors, made up of solid-state 1^st-type conductance horizontal areas located in illumination zone on the 1^st, 2^nd and 3^rd depths, relative to the structure surface, optimised with respect to maximum absorption of red, green and blue components of radiation, are connected via p-n-transitions by the areas of the 1^st and/or 2^nd conductance type. Note here that impurity concentration distribution allows introducing additional 2^nd-type conductance areas to be located outside irradiated areas adjoining aforesaid 2^nd-type conductance areas.

EFFECT: increased or balanced out dynamic range of detectors, reduced cell sizes.
