PROJECTION DEVICE FOR IMAGE DISPLAY, IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD AND COMPUTER PROGRAM Russian patent published in 2017 - IPC G02B26/10 H04N9/31 H04N5/74 

Abstract RU 2630424 C2

FIELD: physics.

SUBSTANCE: image projection device is proposed, and it includes: a projection unit including a light source configured to emit light having an intensity corresponding to a pixel value of the input image and a deflector configured to deflect light emitted from the light source, using a mirror to perform a scan on a projection object; time correction unit configured to perform time pixel data adjustment of the input image in accordance with the deflection angle in the deflector; distortion correction table of the form, comprising a distortion correction value of the form for each calculated position of the distortion correction table of the form; the luminance distortion correction table comprising a luminance distortion correction amount for each calculated position of the luminance distortion correction table and an image correction unit configured to perform distortion correction of the input image by performing signal processing based on the shape distortion correction table and the luminance distortion correction table.

EFFECT: providing a high-quality projection display device capable of automatically correcting distortion in the image.
