FRAME GRABBER, FRAME GRABBER CONTROL METHOD AND MEDIUM Russian patent published in 2014 - IPC H04N5/00 

FIELD: physics, photography.

SUBSTANCE: invention relates to frame grabbers. The result is reached by that the frame grabber includes the generation unit designed with a possibility of generation of the image data, and the resolution unit designed with a possibility, on the basis of the first image data generated by the generation unit, when the position in focus is located in the first focal position, when the object is located in the focused state, or the second focal position on the side of smaller distance of the first focal position, and the second image data generated by the generation unit, when the position in focus is located in the third focal position on the side of greater distance of the focal position, when the back ground is located in the focused state, resolutions of the first area including the object, and the second area including the background.

EFFECT: accurate resolution of the object of shooting and background, even if the image data have poor difference by depth between the object and background.
