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.

a signal input part for receiving image signals input via the tuner, image signals input via an external apparatus, or receiving image signals in response to a movement control signal of the object;

a first switching part for selectively outputting image signals input via the signal input part in response to a control signal of the control part, the image signals being input in response to the movement detection signal of the object;

a first image signal processing part for processing image signals selected by the first switching part;

a storage part for storing the image signals processed by the first image signal processing part;

a second switching part for switching 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 for processing images such that image signals switched by the second switching part are displayable on a display part.

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

a scaler for receiving and scaling image signals switched by the first switching part;

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

an MPEG encoder for MPEG-encoding the image signals whose frame rate has been changed by the frame rate changer.

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

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

an image processor for processing images such that image signals decoded by the MPEG decoder are displayed.

6. The apparatus according to claim 3, wherein the control part controls image signals by movement detection of the object to be stored in the storage part, and simultaneously, controls received broadcasting signals to be viewed when a closed circuit television mode is set through the key input part by a user.

7. A method for controlling a digital image display apparatus having a tuner and a digital video recorder system, the method comprising:

when a movement detection control signal is received from an outside, receiving shot movement images;

receiving the movement images to record the received movement images in the digital video recorder system; and

reproducing the movement images recorded in the digital video recorder system according to a request of a user.

8. The method according to claim 7, wherein the recording of the received movement images in the digital video recorder system comprises recording the movement images and simultaneously viewing images received via the tuner.

9. The method according to claim 7, wherein the movement detection control signal comprises a signal received from a movement shooting unit when a movement of the object is detected by the movement shooting unit.

10. The method according to claim 7, wherein the reproducing of the movement images recorded in the digital video recorder system comprises reproducing the recorded movement images through one of a main screen and a sub-screen such as picture in picture and picture on picture.

11. A digital image display apparatus having a tuner and a digital video recorder system, the apparatus comprising:

a digital image receiving device for shooting an object in an outside, controlling transmitted movement images to be received, recorded, and reproduced through the digital video recorder system only when the shot object moves, and simultaneously, processing images received via the tuner so that the images are viewed.

12. The apparatus according to claim 11, wherein the digital image receiving device comprises:
