BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color video printer. In particular, an image synthesis of a color video printer in which two image data memorized between fields is edited as a tablet, or a character can be printed on edited data or any image data of two field frames. An apparatus and a control method thereof are provided.

In the block diagram of a conventional color video printer, as shown in FIG. 1, a decoder 11 for converting an input image signal into a color signal or a color difference signal, and the analog image data of the decoder 11 as a digital signal. An analog / digital converter 12 for converting, a buffer 13 for selecting which of the input image data and the memorized image data to be output to the monitor 16, and a digital through the buffer 13 A digital / analog converter 14 for converting a signal into an analog signal, an encoder 15 for converting a color signal and a color difference signal of the digital / analog converter 14 into a composite video signal, and a key input unit 22 A system control unit 23 for receiving a key signal from the system and controlling the system; a memory control gate array 17 for storing in the frame memory 18 according to the command of the system control unit 23; According to the instructions of the system control section 23 it was composed of the frame memory (18) tone control gate array (19) for printing by the data stored in the line memory 20 and eomeol print head 21 to write to.

In the conventional circuit configured as described above, the input video signal is converted into color signals (R, G, B) or color difference signals through the decoder 11, and sent to the analog / digital conversion unit 12 so that the analog signals are converted into digital signals. Lose.

In this case, when a memory command is applied to the system control unit 23 through the key input unit 22, the system control unit 23 applies the memory command to the memory control gate array 17 again to convert the image data converted into digital frame memory. It is memorized in (18). At the same time, the image data which has passed through the buffer 13 is converted into an analog signal by the digital / analog converter 14, and is displayed on the monitor 16 via the encoder 15.

When a print command is applied to the system control unit 23 through the key input unit 22 again, the print command is sent to the tone control gate array 19, and the image data stored in the frame memory 18 is transferred to the tone control gate array. In (19), it is sent to the thermal print head 21 via the line memory 20, and the image input by this head 21 is printed.

However, such a conventional technique can only take a simple method of printing the input data as it is, and even if the user wants to edit or insert a character to make a card, a function called Super Impose is used to transfer the characters to other places. After writing, it must be input again through a video device called a camcorder.

In order to solve the above-mentioned problems, the present invention provides a video synthesizing apparatus of a color video printer, which allows editing of desired portions of two image data to obtain a new image, and inserts characters into image data. Invented a control method, which will be described in detail below with reference to the accompanying drawings.

2 is a block diagram of a color video printer according to the present invention. As shown therein, a decoder 31 for converting an input image signal into a color signal or a color difference signal and a digital signal of the analog image data of the decoder 31 are shown. An analog / digital converter 32 for converting the data into an image, a buffer 33 for selecting which of the input image data and the memorized image data to be output to the monitor 36, and the buffer 33 A digital / analog converter 34 for converting a digital signal into an analog signal, an encoder 35 for converting a color signal or a color difference signal of the digital / analog converter 34 into a composite video signal, and a key input unit ( A system controller 43 for receiving a key signal from 42 and controlling the system; an SRAM 44 for storing address data received from the tablet 45 and the pen 46; and the system controller 43. The memory control gate array 37 for storing in the frame memory 38 according to a command, and the data stored in the plane memory 38 according to the command of the system control unit 43 are line memory 40 and thermal print. A control gate array 39 configured to print by the head 41 is provided.

Referring to the effect of the present invention configured as described in detail as follows.

When the input video signal is converted into a color signal or a color difference signal through the decoder 31 and sent to the analog / digital converter 32, the analog signal is converted into a digital signal. At this time, when the memory command is applied to the system control unit 43 by the key input unit 42, the system control unit 43 transmits the memory command to the memory control gate array 37 and converts the image data converted into digital to the frame memory 38. Remember).

At the same time, the image data which has passed through the buffer 33 is converted into an analog signal from the digital / analog converter 34 to an analog signal and displayed on the monitor 36 through the encoder 35.

At this time, when the edit mode is applied through the key input unit 42, the address information input to the tablet 45 by the pen 46 by the system controller 43 is stored in the SRAM 44.

When the print command is input again through the key input unit 42, the system control unit 43 inputs the print command to the tone control gate array 39, and the tone control gate array 39 is stored in the frame memory 38. The image data is taken out in accordance with the address stored in the SRAM 44 and then printed by the line memory 40 and the thermal print head 41.

If this is explained again according to the flow chart, first, in storing image data, the frame is divided into field A and field B, and then memory is checked. If the field A or B memory is checked, if it is field memory, the character mode can be entered before entering the edit mode. So check the text mode. If it is not in text mode, check whether it is in edit mode or execute the entered command.

When the memory is in the field A or B and enters the text mode, the text information is input from the tablet 45 and the pen 46 and the address is stored in the SRAM 44.

In addition, when the image data is stored in both the fields A and B and the editing mode is entered, it is determined whether the memory changeover switch field A or the field B is displayed, and the monitor 36 displays the image of the field switched by the changeover switch.

However, if there is a switch in the frame mode, it is displayed in text to select a changeover switch among fields A or B.

The field A or field B is selected and the memory screen is displayed on the monitor 36 and the portion to be edited from the tablet 45 and the pen 46 is designated. For example, as shown in FIG. If each memory is stored, the user designates the edit portion of the field B as shown in FIG. 5, and returns to the field A to designate the center of the edit portion.

Then, the character input data is also stored in the SRAM 44 when the character is input at the time of discrimination.

Also, at this time, the color or character of the character is set by the user.

When everything is completed, the edited screen is displayed on the monitor 36, and the user is asked whether the O (K) is determined. If the user is satisfied, the next command is executed.

When the operation is completed, the screens of fields A and B of FIG. 4 are assigned, the editing part is designated as in FIG. 5, and the screen is edited (FIG. 6). You can get the screen.

In addition, it is also possible to take a method of directly assigning an address with a light pen to a monitor without separately using a tablet for specifying an editing address and a tablet among pens.

As described in detail above, the present invention can not only obtain a picture of simple data input as image data, but also edit a desired portion of two image data to obtain a new image, and insert characters into the image data. There is an effect that the user can obtain all the desired images.
