Hereinafter, a television with a digital image processing apparatus of the present invention will be described in detail with reference to the accompanying drawings.

First, a schematic configuration and operating state of a conventionally used television will be described with reference to FIG. 1. As illustrated, the television includes a tuner unit 1 for receiving a broadcast signal propagated in the air as a radio signal and passing and outputting only a signal of a specific broadcasting station among the received broadcast signals.

The signal output from the tuner section 1 is input to an IF amplifier section 2 for modulating it and amplifying it to a signal of a particular size. The signal amplified and amplified by the IF amplifier 2 is input to the main IC unit 3 which separates the R, G, and B signals from the audio signal.

The main IC unit 3 includes various circuits therein, and is an IC in which various circuits, audio processing units, and video processing units, which have been conventionally separated, are integrated into one module. Of course, it will be apparent to those skilled in the art to which the present invention pertains that a circuit having a structure different from that of the main IC unit 3 can be constructed. The R, G, and B signals output from the main IC section 3 are input to the CRT driving section 4 and finally output to the CRT 5.

On the other hand, the sound signal output from the main IC unit 3 is output through the speaker 7 after sufficient creeping and amplification in the amplifier 6. The microcomputer 8 has a built-in program for controlling the entire device and detects a command signal input from the outside and performs an operation corresponding to the command signal. Although not shown, the microcomputer 8 is connected to a memory ROM storing channel data necessary for channel selection.

The digital image processing apparatus of the present invention is further added to the conventional television as described above. As shown in FIG. 2, the digital image processing apparatus includes a digital image input unit 11, an image storage unit 12, an image conversion unit 13, a mixer 14, and a format conversion unit 15. ), A control unit 16, and a memory unit 17, and the mixer 18 may use a mixer used for displaying OSD characters in a conventional television.

The digital image input unit 11 receives a file having a specific image data format, for example, a parallel port, or a serial port such as RS-232C. Can be In addition, the specific image data format may be, for example, a photo-CD format, a JPEG, a GIF file, or the like. You can also receive images directly from a digital camera.

Image data input through the digital image input unit 11 is stored in the image storage unit 12. The image storage unit 12 is for recording image data, and is a memory device such as DRAM and EPROM. The image data stored in the image storage unit 12 is directly output according to the control signal from the control unit 16 or after the image data is modulated in the edit state. The controller 16 may be configured as a one chip microcomputer.

The controller 16 is connected to a key input unit 16a which receives a command signal for processing an image stored in the image storage unit 12, so that the user directly outputs the image data without performing any manipulation or manipulation. If it is desired to do so, by not inputting a specific image processing command, the image data of the image storage unit 12 is output to the format conversion unit 15.

The format conversion section 15 is modulated into an NTSC signal capable of displaying video data on the CRT 5 of a television. The format conversion unit 15 stores conversion data for photo-CD, JPG, GIF files, and the like, respectively. After modulating the NTSC signal by the format converter 15, the image data is output to the mixer 18. The mixer 18 is conventionally installed in the television, it is possible to use a mixer for mixing the OSD generated characters input from the OSD generator 19 with the video screen.

When the user wants to modulate the image data, the image data modulation command may be input using the key input unit 16a. That is, the controller 16 performs a process of modulating the image data stored in the image storage unit 12 by the image converter 13 according to a control signal input from the key input unit 16a. The image data modulated by the image modulator 13 is temporarily stored in the memory unit 17. The memory unit 17 may store one image data or a plurality of modulated image data.

The image modulator 17 may perform a simple editing function, for example, an editing function such as cut or paste. However, it will be apparent to those skilled in the art that the present invention can be configured to perform more complicated functions.

The controller 16 may output a control signal to the mixer 14 to output image data stored in the memory unit 17. If there is a plurality of modulated image data, the mixer 14 synthesizes the image and outputs the image to the format converter 15.

The format conversion section 15 converts the input video data into a video format that can be displayed on the CRT 5 of the television, and then outputs it to the mixer 18 again. The mixer 18 is connected to the mixer 18 so that if desired, the user can display specific characters in the image data. 3 is a flowchart showing an operating state of the digital image processing apparatus of the present invention as described above.

Since the image data output by the image processing apparatus of the present invention is output in NTSC format, when the VCR is connected to the output terminal of the television, the output image can be stored on a video tape, so that it can be recorded for a long time like an image album.

As described above, according to the present invention, there is an advantage in that a specific digital image data such as a photo-CD, a digital camera, a JPEG, or a GIF can be displayed on a CRT of a television so that a viewer can watch on a screen.

Although the invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that modifications and variations can be made within the spirit and scope of the invention, and such variations or modifications will belong to the appended claims. .
