METHOD OF DISPLAYING TWO-DIMENSIONAL ON-SCREEN MENU ON STEREO VIDEO SEQUENCE Russian patent published in 2011 - IPC H04N15/00 

FIELD: information technology.

SUBSTANCE: stereo frame is split into two colour images. The images undergo colour calibration. Histograms of pairs of initial colour images and pairs of colour-calibrated images are compared, wherein the scalar value of the difference between histograms is calculated and the minimum difference between histograms of two pairs is selected. A given stereo frame is classified as an on-screen menu if the minimum difference between histograms of two pairs is greater than a first predetermined threshold T₁, the value of which is given in the range t₁∈[0…5]. A given stereo frame is classified as not being an on-screen menu if the minimum difference between histograms of two pairs is less than a second predetermined threshold T₂, the value of which is given in the range T₂∈ [150…200]. Geometric elements on images are sought for, wherein additional operations are performed if the minimum difference between histograms is greater than or equal to the first predetermined threshold T₁ and greater than the second predetermined threshold T₂.

EFFECT: recognising an on-screen menu formed by a third-party device for correct display of said menu on a three-dimensional display.
