Abstract

Provided are an apparatus for controlling a digital image display apparatus having a tuner and a DVR system, and a method thereof. According to the apparatus, a visitor history is selectively stored only when a user is absent or a movement of a visitor is detected using the digital image display apparatus having the DVR system. Accordingly, not only unnecessary images are not stored, but also a function of an image display device is performed and simultaneously images transmitted from a movement shooting unit mounted separately from the digital image display apparatus can be selectively recorded in order to detect a movement of an object. Therefore, the image display apparatus can be more efficiently utilized.

Claims

1. A digital image display apparatus comprising:

a tuner;

a display part configured to display an image signal received by the tuner;

a movement shooting unit configured to detect a movement of an object;

an external input terminal configured to receive a movement image from the movement shooting unit, the movement image being transmitted from the movement shooting unit to the external input terminal only when a movement of an object is detected;

a first switching part configured to switchably output the image signal input from the tuner or the movement image input from the external input terminal;

a storage part configured to store the received movement image;

a control part configured to control the first switching part so that the displaying of the image signal received by the tuner and the storing of the movement image received by the external input terminal are simultaneously performed when the digital image display apparatus is used for viewing the movement image;

a key input part configured to receive a desired command from a user;

a first image signal processing part configured to process the image signal output from the first switching part;

a second switching part configured to switch image signals such that the image signals processed by the first image signal processing part are stored in the storage part or displayed in response to a control signal output from the control part; and

a second image signal processing part configured to process images such that the image signals switched by the second switching part are displayable on the display part.

2. The apparatus according to claim 1, wherein the first image signal processing part comprises:

a scaler configured to receive and scale image signals switched by the first switching part;

a frame rate changer configured to change the frame rate of image signals scaled by the scaler in response to a control signal of the control part; and

an MPEG encoder configured to MPEG-encode the image signals whose frame rate has been changed by the frame rate changer.

3. The apparatus according to claim 1, wherein the second image signal processing part comprises:

an MPEG decoder configured to decode image signals switched by the second switching part in response to a control signal of the control part; and

an image processor configured to process images such that image signals decoded by the MPEG decoder are displayed.

4. The apparatus according to claim 1, wherein the control part is also configured to control image signals by movement detection of the object to be stored in the storage part, and simultaneously, to control received broadcasting signals to be viewed when a closed circuit television mode is set through the key input part by a user.

5. A digital image display apparatus comprising:

a tuner;

a digital video recorder system;

a display part configured to display an image signal received by the tuner;

a digital image receiving device configured to shoot an outside object, and to control transmitted movement images to be received, recorded, and reproduced through the digital video recorder system only when the shot outside object moves, and simultaneously, to process images received via the tuner and to display the image signal received by the tuner;

a signal input part configured to receive image signals output only when a movement of the object is detected from an outside, via the tuner or via an external apparatus;

a first switching part configured to selectively output image signals input via the signal input part;

a key input part configured to receive a desired command from a user;

a control part configured to record or view image signals switched by the first switching part in response to a user request command input via the key input part;

a first image signal processing part configured to process image signals selected by the first switching part;

a storage part configured to store the image signals processed by the first image signal processing part;

a second switching part configured to switch image signals such that the image signals processed by the first image signal processing part are stored in the storage part or displayed in response to a control signal of the control part; and

a second image signal processing part configured to process images such that the image signals switched by the second switching part are displayable on a display part.

6. The apparatus according to claim 5, wherein the first image signal processing part comprises:

a scaler configured to receive and scale image signals switched by the first switching part;

a frame rate changer configured to change the frame rate of image signals scaled by the scaler in response to a control signal output from the control part; and

an MPEG encoder configured to MPEG-encode the image signals whose frame rate has been changed by the frame rate changer.

7. The apparatus according to claim 5, wherein the second image signal processing part comprises:

an MPEG decoder configured to decode image signals switched by the second switching part in response to a control signal of the control part; and

an image processor configured to process the image signals such that the image signals decoded by the MPEG decoder are displayed.
