Abstract
Disclosed herein is a projection type image display apparatus, including: a projecting portion projecting an input image on an image projected body; a camera portion photographing the image projected body; a display control block controlling display of a projected image projected by the projecting portion; and a gesture recognizing unit recognizing a gesture manipulation of a user contained in the image photographed by the camera portion.
Claims18
A projection type image display apparatus, comprising:
- a projecting portion configured to project an input image on an image projected body;
- a camera portion configured to photograph a plurality of images of the image projected body at respective time intervals;
- an image correction amount calculating unit configured to calculate an image correction amount of the projected input image;
- a control block configured to:
- control display of the projected input image;
- and
- correct a distortion in the projected input image based on the image correction amount to obtain a corrected input image;
- and
- a gesture recognizing unit configured to:
- detect a change between a plurality of frames of the photographed plurality of images for the respective time intervals;
- and
- recognize a gesture manipulation on a projection surface of the projecting portion,
- wherein the gesture manipulation corresponds to a user contained in a photographed first image of the plurality of images;
- and
- provide a gesture manipulation area based on the detection of the change between the plurality of frames of the photographed plurality of images for the respective time intervals,
- wherein the gesture manipulation area corresponds to a portion of the image projected body on which the corrected input image is prevented from projection;
- and
- display a guide display area within the gesture manipulation area,
- wherein the guide display area guides the recognized gesture manipulation that corresponds to the user in an orientation, and
- wherein the orientation is one of a counterclockwise orientation or a downward orientation.
