Document Type and Number:
Japanese Patent JP4507129
Kind Code:
B2
Abstract:
A tracking point detecting device includes: a frame decimation unit for decimation the frame interval of a moving image configured of multiple frame images continuing temporally; a first detecting unit for detecting, of two consecutive frames of the decimated moving image, a temporally-subsequent frame pixel corresponding to a predetermined pixel of a temporally-previous frame; a forward-direction detecting unit for detecting the pixel corresponding to a predetermined pixel of a temporally-previous frame of the decimated moving image, at each of the decimated frames in the same direction as time; an opposite-direction detecting unit for detecting the pixel corresponding to the detected pixel of a temporally-subsequent frame of the decimated moving image, at each of the decimated frames in the opposite direction of time; and a second detecting unit for detecting a predetermined pixel of each of the decimated frames by employing the pixel positions detected in the forward and opposite directions.
