THREE-DIMENSIONAL DISPLAY DEVICE AND THREE-DIMENSIONAL DISPLAY METHOD

摘要

A three-dimensional display device includes: a display region candidate deciding unit that decides a candidate region of an additional image which shields part of a main image of a three-dimensional image on a screen; a depth suitability determination unit that determines whether a difference in depth between the main image and the additional image is within a tolerance range; an image compositing unit that superimposes the additional image upon the candidate region on the main image, and displays the composited image; and a possibly-unsuitable region deciding unit that decides, in the main image, a first region that may protrude to a near side beyond a predetermined depth range, and a second region that may recess to a far side beyond a predetermined depth range. The display region candidate deciding unit further decides a candidate region to shield the first and second regions.

主权项

1. A three-dimensional display device comprising:
a display region candidate deciding unit that decides one candidate region from a plurality of display region candidates of an additional image which shields part of a main image of a three-dimensional image on a screen; a depth suitability determination unit that determines, in a case of assuming that the additional image is to be displayed in the candidate region which the display region candidate deciding unit has decided, whether or not a difference in depth between depth of the main image displayed at a boundary region which is a region on the main image and within a predetermined distance from a boundary line of the candidate region, and the depth of the additional image, is within a predetermined tolerance range; an image compositing unit that, in a case where determination is made by the depth suitability determination unit that the difference in depth is within the tolerance range, superimposes the additional image upon the candidate region on the main image, thereby compositing the main image and the additional image, and displays an image obtained as a result of the compositing on the screen; and a possibly-unsuitable region deciding unit that decides, in the main image, a first region that has a possibility of the depth protruding to a near side beyond a predetermined depth range, and a second region that has a possibility of the depth recessing to a far side beyond a predetermined depth range, wherein the display region candidate deciding unit further decides a candidate region to shield the first region and the second region decided by the possibly-unsuitable region deciding unit.
