Abstract

PURPOSE:To make the easy and accurate setting of conditions of insert patterns with simple constitution by controlling monitor images by the use of an offlined image pickup system. CONSTITUTION:The video information from an image pickup system by a TV camera 2 and a processing circuit 3 for image pickup signals is stored in the memory of an image simulation device 4. Main patterns are monitored by a color monitor 8 via a gate amplifier 5, a mixing circuit 6 for insert pattern signals, etc. The video information in the insert patterns by the offlined image pickup system is applied to a generator 9 for insert pattern signals, and the gate of an amplifier 5 is closed by the image information from a comparator circuit 12, by which the video information components of the portions to have the insert patterns are extracted from the main patterns. The color video information of the insert patterns by a regulator 16 for the color of the insert patterns of a device 9 is applied via a circuit 6 to said portions, and the insert patterns are also displayed on a monitor 8. Thus the accurate conditions for the insert patterns for the purpose of printing, etc. are set easily by the simple constitution without requiring layout scanning, etc.

Description

[Detailed Description of the Invention] The present invention provides that, at the stage of planning printed matter such as posters and catalogues, characters or marks such as catchphrases, explanatory sentences, etc. When inserting a design into the main design, what position, what size, and what color should be used to create the best result? It harmonizes with the main picture and is easy to read.
And - whether the printed image has a strong appeal to the viewer,
The present invention relates to a method and apparatus for simulating a color monitor (color CRT) and setting its conditions, and particularly relates to a method and apparatus for setting conditions that are simple and capable of setting preferable conditions.

Conventionally, it has been common practice in layout scanners and TV broadcasts to mix inset designs such as letters and patterns with the main picture reproduced on a color monitor.

As an example of a layout scanner, for example, 5CI-TE
The R-300 type device from Company X (Israel) is configured as follows. First, a mount with inlaid letters and patterns is used; 1. L. The mount is input with a scanner. .Next, the information created manually is called up on the color monitor, and the color of each area of 1111"ffi is instructed, and the text and pattern are inserted by editing along with the main pattern information. We are doing a lot of work.

However, fitting using a darning layout scanner is extremely expensive in terms of equipment, and performing this type of simulation is too expensive and takes a long time.
Its operation is complicated, and it is not a commonly used device for this kind of work.In addition, in the case of TV broadcasting, two cameras are prepared and one camera is used to shoot the main image. ,
The other camera is used to photograph the inlaid designs and composite them.

However, with such a TV superimposition σ) method, it is impossible to set the exact conditions required for the mark (j).

The present invention is a simple device, and only a small amount is required for printing.
The present invention relates to a method and device for setting conditions for an inset drawing and pattern, which allow accurate setting of conditions for the part to be used and are easy to handle.

NT@mtlc no 1 ri 48 1116 mark (in 1.
In step tc), a color original or color separation plate of the main picture placed on an original stand (1) containing a light source is converted into a video signal by a television camera (2). This video signal is subjected to gamma correction and black-and-white reference level adjustment by the video signal processing device (3), and the image simulation device (mark @11) electrically simulates the finished image.
4).

This device (4)K has a built-in storage device that corresponds to the printing YoM and C1BK versions, and the output signal is RlG.
, B are obtained and displayed on a color monitor (8). After the memory of each version of yoM, c, and BK, that is, the storage of the main picture is completed, the imaging devices such as the document stand (11), the television camera (2), and the processing device (3) go offline.

This invention focuses on this point, and by using an offline imaging system without adding new memory, it incorporates one inset design such as letters or patterns into the image of the main design, so that the main design has the most This makes it possible to easily and quickly simulate the hue, size, position, etc. of matching characters and patterns.

A film with an inlaid pattern (positive or negative) containing characters and patterns is placed on the original holder +i+ of the offline imaging device, and this image is transferred to the TV camera (2).
Take an image with The size can be freely changed by using a zoom lens, and the position can be changed freely by changing the position where the film is set.

The video signal of the inset pattern passes through the clamp drive amplifier 0ω-, and the black level is set to 0V by the clamp circuit (IIIK).
K-clamp. The video signal with a constant black level is converted into binary data (High level or Low level) & cf by a comparator circuit (121).The Schlessier hold adjuster (131) determines which level to consider as High level. The inset pattern signal of the binarized characters and patterns is sent to the buffer amplifier (14), and the video signal is gated by the gate amplifier (5,).In other words, the image of the part where the inset pattern should be inserted is gated. The signal component is extracted from the main image.

On the other hand, the binarized embedded pattern signal is transmitted to the embedded pattern signal amplifier (
151, it is inverted and amplified and the inset design color direction adjuster (16
Connected to 1. By appropriately adjusting the levels of these six adjusters, it is possible to freely adjust the color of the embedded design. For example, if you want the color of the characters or patterns to be inserted to be red, you can adjust so that a signal is applied only to the B channel and zero signals are applied to the G and B channels. Similarly, in addition to the G and 13 basic colors, by appropriately combining the RoG and B channel signals, Y, M,
Not only C, but also these intermediate colors and gray (R, G, B
It is possible to mix inlaid designs of all shades, such as by mixing equal amounts.

The signal adjusted by the inset pattern color adjuster (161) is applied to that part of the video signal of the main pattern where the part where the inset pattern is already at zero level by the inset pattern signal mixing circuit (6). The video signal after mixing is used by the video output amplifier (7) to drive the color i-monitor (8), allowing you to view a color image with characters and patterns incorporated therein.

With the above configuration, the present invention has the following excellent practical effects from qjj7%. In other words, compared to conventional layout scanners, operations such as input are easier, and in particular, in order to change the position, angle, and size of the inset pattern, you simply move the position of the original with the inset pattern on the document holder. It is only necessary to change the zoom ratio (or change the zoom ratio).Since there is no need for coordinate transformation by a computer, it is possible to create an apparatus that is extremely easy to work with and is also extremely inexpensive.

Furthermore, with the superimposition method of television, it is not possible to obtain various conditions necessary for printing, such as changing the color tone of the inset design, but with the apparatus of the present invention, various conditions necessary for printing can be obtained accurately and quickly. can do 1
