Abstract

PURPOSE:To quickly and accurately write pictures in a wide range covering a small area through a large area with use of an optical signal detecting means, by setting variably a designated unit area or shape of the optical signal detecting means. CONSTITUTION:When a light pen 6 is applied to a desired area and coordinates on a TV monitor 7, the signals corresponding to the coordinates are inputted to a light pen signal processing circuit 5 and then to a unit marker varying circuit 4. The circuit 4 sets the area or the shape of a unit marker designated by the pen 6. The output of the circuit 4 is written or erased via a memory 3. Then the video signals with which a marker outputted from the memory 3 is multiplexed by a multiplexing circuit 2 are displayed on a TV monitor 7. Therefore, a small area can be written on a screen by reducing the area of the unit marker via the circuit 4. While a large area of the screen can be quickly painted out when the area of the unit marker is increased.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image processing apparatus for marking an area on a television monitor screen using an optical signal detection means such as a light pen or a mouse.

[Prior Art] Fig. 5 shows a conventional image processing device using, for example, a light pen. In Fig. 0, (1) is a video signal, and (2) is a video signal (1) is input. Multiple circuit, (3
) is a memory, and (4) is a light pen signal processing circuit that processes the output from the light pen (6) and inputs it to the memory (3).

Next, the operation will be explained.

A video signal (1
) is input to the multiplex circuit (2). Here, memory (3
), the video signal (1) is displayed as is on the television monitor (7).

On the other hand, when using the light pen (8), when the light pen (6) is brought into contact with the desired coordinates on the television monitor (7), a signal corresponding to the coordinates is sent to the light pen signal processing circuit (5). is input. The signal processed by the light pen signal processing circuit (5) is transmitted to the memory (3), and is written or erased for each coordinate as necessary. The signal output from this memory (3) passes through a multiplex circuit (2), is superimposed on the video signal (1), and is sent to a television monitor (7).

[Problems to be Solved by the Invention] The conventional image processing device is configured as described above, and the unit area or unit shape designated by the light pen is fixed. Therefore, if you fix it to a small unit shape, it is possible to accurately fill out an area, but it takes a lot of time and effort to fill out a wide area, such as the entire screen.On the other hand, if you fix it to a large unit shape, it takes a lot of time and effort. , there were problems such as difficulty in filling in detailed areas.

This invention was made to solve the above-mentioned problems, and it is an image processing method that allows marking from small areas to wide areas easily and quickly using an optical signal detection means such as a light pen. The purpose is to obtain equipment.

[Means for Solving the Problems] An image processing device according to the present invention is provided with a unit marker variable circuit that arbitrarily sets a specified unit area or unit shape of an optical signal detection means such as a light pen. It is.

[Function] In the image processing device of the present invention, for example, the designated unit area or unit shape of the light pen is variable;
If the area of the unit marker is set small, a detailed area can be filled on the screen, and if the area of the unit marker is set large, a wide area can be quickly filled in on the screen.

[Embodiments of the invention] An embodiment of the present invention will be described below with reference to the drawings.

explain.

FIG. 1 shows an example of an image processing apparatus according to the present invention, and parts that are the same as those in the conventional apparatus are given the same reference numerals, and a description thereof will be omitted. In the figure, (4) is a unit marker variable circuit connected to the output side of the light pen signal circuit (5), so that the unit area or unit shape designated by the light pen can be arbitrarily set.

Next, the operation will be explained.

When the light pen (8) is brought into contact with the desired area/coordinates on the television monitor (7), a signal corresponding to the coordinates is input to the light pen signal processing circuit (5), and furthermore, the unit marker variable circuit (4) is input to the light pen signal processing circuit (5). ) is input. In this unit marker variable circuit (4), the area or shape of the unit marker designated by the light pen can be arbitrarily set. The output from the variable marker circuit (4) is stored and erased in the memory (3), and the input video signal (1) is sent to the multiplex circuit (2).
), and the marker multiplexed video signal is displayed on a television monitor (7).

Here, as an example, as shown in Fig. 2, 256 dots horizontally,
Television monitor divided into 230 vertical lines (7
). Fill in the area using a small rectangle on this screen as the minimum unit.

If you set the unit marker variable circuit (0) to the minimum unit of 1 dot x 1 line shown in Figure 3, for example, you can use the light pen (8) to draw very fine and precise areas on the screen. In addition, if you set the unit marker variable circuit (for example, the 6 dots x 6 lines rectangle shown in Figure 4 as the minimum unit in the 4-t), the area of the unit marker becomes large, making it possible to quickly fill in a wide area. Of course, you can also add a unit marker, e.g.
If you set a large number, such as 0 dots x 20 lines, you can fill in the area more quickly.

In the above embodiment, the unit marker is set to a rectangular shape, but the unit marker is not limited to this, and it is also possible to set it to any other shape such as a circle or a triangle, and use it according to the purpose. It can also be used as a ``doodle board'' by setting the unit markers in the shape of a bird or flower, for example.

[Effects of the Invention] As described above, according to the present invention, since the unit marker variable circuit is provided to variably set the specified unit area or unit shape of the optical signal detection means, it is possible to quickly set the specified unit area or unit shape of the optical signal detection means. In addition, a screen processing device capable of accurately specifying and filling in areas can be obtained.
