METHOD OF INCREASING RESOLUTION OF IMAGES OBTAINED USING MATRIX PHOTODETECTORS Russian patent published in 2020 - IPC H01L31/232 H04N5/335 

FIELD: image forming devices.

SUBSTANCE: invention relates to obtaining images and a method of increasing image resolution obtained using a matrix photodetector. Method is based on receiving optical radiation with photosensitive elements of a matrix photodetector with alternate overlapping of a portion of the photosensitive surface of the matrix photodetector and using an algorithm for calculating the obtained subpixels, which consists in 3-stroke action. At the first cycle, optical radiation intensities are measured by fully open photosensitive elements of the photodetector array (PSE PDA). At the second stroke, a portion of the photosensitive surface (PSS) of each PSE PDA with area S=S_PSE/2 vertically overlaps with the transparency and total intensity of optical radiation of its open part is measured. On the third cycle, part of the PSE PDA is horizontally covered and the total intensity of optical radiation of the open part of the PSE PDA is measured, calculating each intensity of optical radiation falling on the calculated PSE PDA subpixels, and generating an image with a resolution increased by 4 times.

EFFECT: technical result consists in improvement of resolution of optical-electronic means without changing dimensionality of photodetector array.
