METHOD FOR INCREASING SENSITIVITY AND FRAME RATE OF VIDEO CAMERAS Russian patent published in 2021 - IPC H04N5/347 H04N5/3745 

FIELD: video processing.

SUBSTANCE: invention relates to the field of increasing the sensitivity and frame rate of video cameras. The proposed method for increasing the sensitivity and frame rate of video cameras consists in applying a binning procedure to adjacent pixels of a radiation receiver matrix for a sequence of video frames, wherein, in neighboring video frames, binning is performed with a shift of at least one pixel of the radiation receiver matrix diagonally so that a space-time grid with a staggered arrangement of brightness values obtained by binning pixels is formed in neighboring video frames, then video frames with an increased or initial frame frequency obtained by binning are read and digitized, after which dimensions of these video frames are increased to original dimensions by introducing zero columns and rows into their matrix structure, and then the sequence of increased video frames is interpolated using a three-dimensional interpolation spatiotemporal low-pass filter with a transmission area in the form of an octahedron.

EFFECT: increase in the sensitivity and frame rate of video cameras, when an increased spatial resolution is achieved.
