The operation and operation of the inventive image signal editing processing apparatus configured as described above will be described with reference to FIGS. 1 to 4.

As shown in FIG. 1, the real imager 10 used as the image signal editing and processing apparatus of the present invention is an object to be used as a material on the real mounting table 100 (for example, an object having a three-dimensional shape). Etc.) and the real image is read by the camera 110 and provided as an image (signal) to various display apparatuses or video signal editing processing apparatuses according to the present invention. At this time, the lighting 120 removes the real shadow or adjusts the brightness. In some cases, the microphone 130 of FIG. 2 receives the voice or sound of the field and provides the same to the output distribution unit 140.

When the video signal by the real imager 10 is input to the output distribution unit 140 as described above, the output distribution unit 140 is an image currently input from the camera 110 and the microphone 130 of the real imager 10. And whether to output the audio signal to the digital signal processor 150 or the analog signal processor 180 according to the user's intention.

If the user directly outputs a voice signal through the speaker 190 and wants to display the current lecture content or conference content through the display unit 200 such as a television, or the like, the video or audio signal may be transmitted through a VCR or the like. If you want to record The output distributor 140 may provide outputs of the camera 110 and the microphone 130 to the analog signal processor 180.

If the analog signal processing unit 180 is to output audio through the speaker 190, it outputs by amplifying a predetermined level, and also to display the video signal through the display unit 200, such as a television, or a storage medium such as a VCR. If it is stored through 210, the analog video signal is processed and output according to the display and storage method thereof.

However, since the image signal processed by the analog signal processor 180 is not a suitable signal for printing through the printer 160 but is not a suitable signal for use in the PC 170, that is, the digitized signal No, the process of converting it into a digital signal is essential.

Therefore, the output distribution unit 140 provides the digital signal processor 150 with the image signal read from the camera 110 according to the user's intention. The digital signal processor 150 processes the analog video signal to be input to the printer 160 and processes it to be displayed as an image through the PC 170. This will be described in detail with reference to FIGS. 3 and 4. Explain.

The analog image signal applied from the output distribution unit 140 is converted into a digital image signal by the analog / digital converter 151 of the digital signal processor 150, and the converted digital image signal is converted into the digital signal processor 150. Is input to the frame memory 152 and stored in units of one frame. At this time, as long as the memory control unit 153 is inputted Information on the video signal of the frame, that is, information on the size of the frame, and the like, so that the video signal of the correct one frame can be stored in the frame memory 152 according to the information of the frame. For example, the storage state of the frame memory 152 is controlled by the information of the start position and the end position of the video signal of one frame.

The frame-based image signal stored in the frame memory 152 of the digital signal processor 150 is interfaced with the PC 170 through the PC interface unit 156 and output. At this time, since the video signal stored in the frame memory 152 is a continuous video in a frame unit, the video signal read from the camera 110 of the real imager 10 is displayed as an image on the monitor of the PC 170. If the user inputs a capture signal while printing the image currently read from the camera 110 while the image is displayed through the monitor of the PC 170, the microcomputer 157 drives the frame capture unit 154 to present the image. Only an image signal of one frame stored in the frame memory 152 is accepted. Then, when a print command is generated from the user, the microcomputer 157 controls the frame capture unit 154 to output the captured image signal of the frame to the printer 160 through the interface unit 155 for the captured image. It is printed immediately without passing through this PC 170.

When the image capture signal is not generated from the user, the microcomputer 157 provides the PC 170 with a continuous image through the PC interface unit 156 as described above. At this time, if a video signal of one frame is input from the PC 170, that is, the video signal of one frame in which an image of one frame read from the camera 110 is edited or processed according to a user's intention is displayed on the PC interface unit. If you enter (156), my The comb 157 controls the frame capture unit 154 to receive one frame image signal from the PC interface unit 156. Accordingly, the frame capture unit 154 captures and stores an image of one frame input from the PC interface unit 156, and then, when a print command is generated from the user, the microcomputer 157 controls the frame capture unit 154. By outputting the captured image signal of the frame to the printer 160 through the printer interface unit 155, the image signal input from the PC 170 is also printed through the printer 160.

The image displayed through the monitor of the PC 170 is displayed in the image region 300 by the image signal window processing unit 260 as shown in FIG. 4, and the control region 400 is also shown in FIG. 4. The user inserts a character into the image displayed in the image region 300, rotates the image, or adjusts colors by using various (icon) buttons provided in the control region 400. That is, when the user attempts to input a character by operating the icon button provided in the control area 400 on the image displayed in the image area 300, the character insertion processing unit 210 performs this. If the user wants to rotate the image displayed on the image area 300 at a predetermined angle, for example, at an interval of 90 degrees, by operating an icon button provided in the control area 400, the image signal rotation processor 220 Do this. In addition, when the user attempts to adjust the color and color / monochrome by controlling the icon button provided in the control area 400, the color adjustment processor 230 performs the image displayed in the image area.

On the other hand, when the image recorded on the storage medium 210 (for example, a compact disc or video tape, etc.) is reproduced by the digital signal processor 150 immediately It may be printed through the printer 160 or may be used in the PC 170. That is, if you want to print the image stored in the compact disk or video tape or to use in the PC 170, the image captured by the process described above by applying the image signal to be reproduced to the digital signal processing unit 150 applied in the present invention May be printed to the printer 160 and used by the PC 170. In addition, when a remote transmission means (for example, a modem or the Internet) is applied, the captured image output from the digital signal processing unit 150 can be easily transmitted to a remote destination that the user wants to transmit. This is possible by connecting a remote transmission means to a port to which the printer 160 or the PC 170 is connected.
