Abstract
A non-contract selecting device is disclosed. The non-contract selecting device include a light source, emitting light to an outside; a camera unit, generating and outputting a video signal corresponding to an external video; a video data generating unit, generating video data corresponding to the video signal; and an identity unit, detecting a location of a detected area formed by light, reflected by pointing-means and inputted, of the light emitted from the video data in units of each frame, recognizing a moving locus of the detected area by comparing at least two continuous frames and generating and outputting corresponding change information. With the present invention, the function-selecting can be more quickly and easily and increase making the most use of elements.
Claims41
An image signal processor, comprising:
- a video data generating unit, generating video data corresponding to a video signal inputted from an image sensor;
- and
- an identity unit, detecting a location of a detected area formed by a predetermined light component from the video data in units of each frame, recognizing a moving locus of the detected area by comparing at least two continuous frames and generating and outputting corresponding change information,
- wherein the detected area is formed by light, reflected by a pointing-means and inputted, of light emitted to an outside by a light source.
An application processor, comprising:
- a receiving unit, receiving video data generated corresponding to an outside video signal from an image signal processor;
- and
- an identity unit, detecting a location of a detected area formed by a predetermined light component from the video data in units of each frame, recognizing a moving locus of the detected area by comparing at least two continuous frames and generating and outputting corresponding change information,
- wherein the detected area is formed by light, reflected by a pointing-means and inputted, of light emitted to an outside by a light source.
A method of a digital processing device having a photographing function that performs a non-contract mouse function, the method comprising:
- a light source emitting light to an outside;
- a camera unit generating and outputting a video signal corresponding to an external video;
- a video data generating unit generating video data corresponding to the video signal;
- and
- an identity unit detecting a location of a detected area formed by light, reflected by a pointing-means and inputted, of the light emitted from the video data in units of each frame, recognizing a moving locus of the detected area by comparing at least two continuous frames and generating and outputting corresponding change information,
- wherein the change information that any one of a plurality of information items, displayed on a display unit, is selected, or a mouse cursor moving corresponding to the change information is displayed.
