Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an image processing device used together with a video tape recorder or the like for editing recorded video tapes. Background of the Invention In recent years, with the spread of camera-integrated video tape recorders, video editing has also become commonplace. Editing is generally done using a video tape recorder for playback, a video tape recorder for recording, and a titler, wiper, superimposer, etc. interposed between them. Problems to be Solved by the Invention In the above-mentioned conventional technology, a character generating device such as a titler or a superinvozer and a special image processing (graphic processing, etc.) device are required as editing equipment, and the editing equipment is expensive. Furthermore, there were few treatments that were functionally satisfactory.

Means for Solving the Problems In order to solve the above problems, the present invention provides an image processing system mainly for video recorders that can utilize the excellent character generation and graphic processing functions of word processors and personal computers, which are increasingly being used by individuals. It is a processing device, and includes input means for inputting character and graphic information from a word processor or personal computer, memory means for storing the input information, and image information from a video tape recorder on the playback side and storage in the memory means. a synchronization processing means for synchronizing the stored information, a composition processing means for performing composition processing on the image information and the stored information, and an output means for outputting the image information composited by the composition processing means to the recording side video tape recorder. It is something.

Function: Since the image processing apparatus according to the present invention utilizes the character generation function and graphic processing function of a word processor, personal computer, etc., image processing can be performed at extremely low cost and in a wide variety of ways.

Embodiment An embodiment of the image processing apparatus of the present invention will be explained with reference to FIGS. 1 and 2. FIG. 1 is a conceptual diagram of the connections of equipment for editing videotapes, and FIG. 2 is a block diagram for explaining the image processing apparatus of the present invention used in FIG.

According to FIG. 1, l is a video tape recorder on the playback side, 2 is a word processor for creating titles for editing, characters such as superimposition, and graphics, and 3 is a video tape recorder on the playback side. This is an image processing device that combines the video information output from the table recorder 1 with characters and figures created by a word processor and outputs it to the video recorder 4 for recording. Note that the video tape recorder 1 on the playback side may be replaced as long as it can supply images; for example, it may be a camera-integrated video table recorder with a playback function or a video disk player, and the word processor 2 also has a character creation function or It may be replaced as long as it can create a figure. For example, it is possible to replace it with a personal computer. To explain the image processing device in detail with reference to FIG. 2, 10 is a first input unit for inputting screen data such as characters and images output from the word processor 2, and 11 is a first input unit for inputting the inputted information from serial data to parallel data. 12 is a memory section that stores screen data such as converted characters and images; 13 reads out the screen data stored in the memory section 12 and sends it to the composition processing section 14; 15 is a second input section for inputting image information from the video recorder 1 on the playback side;
4, detects a horizontal synchronization signal and a vertical synchronization signal from the composite video signal of the image information from the playback side video table recorder 1, and controls the readout timing of the screen data in the memory readout section 13. It is connected to a synchronization processing section 16 that sends pulse signals to prevent synchronization errors during synthesis processing. 17, the screen data of the data conversion section 11 is transferred to the memory section 12 by input from the operation section l8.
This is a microcomputer section including an 8-bit microcomputer that instructs the screen data in the memory section 12 to be sent to the memory section 13, reads the screen data from the memory section 12 to the memory reading section 13, and sends the screen data to the composition processing section 14. Note that when sending screen data from the memory reading unit 13 to the composition processing unit 14, the microcomputer unit 17 superimposes,
Memory reading section 1 for scrolling and wiping
3 controls the sending of screen data to the composition processing unit 14,
In the composition processing section 14, the image information from the reproduction side video tape recorder 1 is combined and outputted from the output section 19 to the recording side video tape recorder 4 as a superimposed, scrolled and wiped image. The composition processing section 14 also performs coloring, fade-in, and fade-out of screen data according to instructions from the microcomputer section 17. Furthermore, in the above embodiment, the data converter 1
1 was explained as converting screen data, which is serial data, into parallel data, but depending on the microcomputer section 17,
There may be cases where conversion is not necessary, and in that case, the data converter l1 is not necessary and serves as a reading unit that simply reads the screen data from the first input unit 10. Furthermore, in the above embodiment, the microcomputer section 17, the memory section 12, etc.
Although each part has been described as a separate block, it is possible that the parts may be integrated into one or more electronic circuits such as integrated circuits.

Note that FIG. 3 shows another embodiment of the present invention, and the explanation will be omitted with the same parts as in FIG. When switched to a video tape recorder 1 on the playback side, the video on the playback side is blank (but by generating a video signal, it is possible to add a background color such as a blue background, and of course the image information is superimposed and inserted into the video tape recorder 4 on the recording side. Effects of the Invention As described above, the image processing apparatus of the present invention includes a first input means for inputting screen data from the outside, a memory means for storing this screen data, and a first input means for inputting screen data from the outside. a second input means for inputting image information; a synchronization signal detected from the image information and applied to the memory readout means to synchronize the screen data and the image information; A synchronizing means, a control means comprising a microcomputer that stores data in the memory means, reads out the stored screen data to the memory reading means, processes the screen and sends it to the composition processing means, and composition processing by the composition processing means. Since the system includes an output means for outputting image information to external input, it is possible to perform a wide variety of image processing at an extremely low cost by using the character generation and graphic processing functions of word processors and personal computers.
