Embodiment Construction

[0069] Embodiments of the present invention are described below with reference to the drawings. figure 1 is a block diagram illustrating a configuration example of an image processing apparatus according to one embodiment of the present invention. In this image processing device 100 , an input image signal from an input device not shown is input to an initial tracking point determination unit 101 , a layering unit 103 , a third layered motion detection unit 111 , and an output image generation unit 113 .

[0070] figure 2 is a block diagram illustrating a detailed configuration example of the initial tracking point determination unit 101 . Such as figure 2 As shown, the initial tracking point determining unit 101 is provided with an image signal presenting unit 1010 and a tracking point specifying unit 1011 .

[0071] The image signal presenting unit 1010 is configured, for example, as a display or the like so as to display an image corresponding to the input image signal...

Abstract

The present invention relates to a tracking point detecting device and method, program, and recording medium. 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.

Description

technical field [0001] The present invention relates to a tracking point detection device and method, a program and a recording medium, in particular to a tracking point detection device and method, a program and a recording medium that allow a user to simply and reliably track an expected tracking target. Background technique [0002] Hitherto, there have been a large number of techniques for tracking a target specified by a user within a moving image, and such a technique has been proposed in, for example, Japanese Unexamined Patent Application No. 2005-303983. [0003] The technology proposed in Japanese Unexamined Patent Application No. 2005-303983 employs a method in which motion of an initially designated tracking target is detected and a tracking point moves according to the motion. Therefore, there is a problem that when the tracking target involves rotation or deformation, the movement of the tracking point tries to conform to the rotation or deformation, whereby th...
