Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a television game device, and more particularly to a television game device in which a background is synthesized with a game image using a monochrome television camera.

Generally, in the case of video game devices, the background for the game image is displayed in a uniform color, or
Or even if a pattern is displayed in the background, it is displayed using a simple color pattern.

This is because game images are generally configured to read out image signals stored in storage elements such as ROM and display them on a cathode ray tube.
This is due to the fact that as the number of picture elements increases, the number of storage elements increases proportionally, resulting in a very expensive television game device.

However, there is a tendency for video game devices to be more three-dimensional than two-dimensional, appropriately complex rather than simple, and concrete rather than abstract.

When trying to embody these demands with a conventional game board, it would require a large number of memory elements for complex game images, and it would be necessary to display a concrete landscape or complex object as a background. In some cases, a memory element larger than that for game images is required, resulting in a very expensive device.

Therefore, in view of these circumstances, it is an object of the present invention to eliminate the above-mentioned drawbacks by inexpensive technical means and to provide a television game device having a more advanced display form.

The features of the present invention are that a conventional video game device is equipped with a subject that should be used as a background, such as a photograph or a model, a monochrome television camera to photograph the subject, and a color image signal that appropriately distributes the image signal from this camera into color image signals. A signal conversion circuit and an image signal synthesis circuit are provided, and the distributed color image signal is configured to be synthesized with a conventional television game image as a background.

Hereinafter, the present invention will be described with reference to preferred embodiments of the accompanying drawings.

The drawing is a block diagram of the television game device of the present invention, and in order to make the signal system easier to understand, the well-known deflection synchronization signal system will be omitted from the description.

First, subject 2 is composed of a photograph or a model, etc.
is photographed by a monochrome television camera 1 to form a monochrome image signal.

Here, it goes without saying that the subject 2 is not limited to the above-mentioned objects and can be any object as long as it can be easily stored in the video game device.

This monochrome image signal of the subject 2 is pseudo-converted into a color image signal by a color image signal conversion circuit 3.

The configuration of this conversion circuit 3 is, for example, to convert a change in brightness into a change in hue, dividing the brightness level into three stages, and converting the divided image signals into RGB appropriately.
Conceivable configurations include dividing the frequency distribution into three stages to convert frequency changes into hue changes, and appropriately distributing the divided image signals to RGB. is appropriately selected depending on the subject 2 and taking into consideration the visual effect of the background.

The RGB pseudo-color image signal from the conversion circuit 3 is synthesized with the game color image signal formed by the game board 4 by the image signal synthesis circuit 5, and the game image signal with the background of the subject 2 is displayed on the color cathode ray tube 6. Input as an image signal.

Here, the display format from the game board 4 to the cathode ray tube 6 is the same as the conventional device, and the circuit 5 for synthesizing the two image signals is also conventionally well known in television technology, so a description thereof will be omitted.

With the above configuration, the subject 2 is displayed on the screen of the color cathode ray tube 6, that is, the background 61, and the game image 62 is displayed using the color image signal stored on the game board 4.

Here, it is more effective to use a long roll-shaped photograph as the subject 2, move the subject, that is, move the background, or vibrate a photograph or model that is larger than the viewing angle of the camera 1, that is, vibrate the background to enhance the background effect. can be used for

As explained above, according to the video game device of the present invention, since the background is displayed on the cathode ray tube that displays conventional game images using an inexpensive monochrome television camera, it is possible to display a more complex and specific background or Despite the three-dimensional background, the increase in expensive memory elements can be prevented. Furthermore, the memory elements previously used for backgrounds can be used for game images, and the game images themselves can be made more sophisticated.

Further, as described above, it is possible to provide an unprecedentedly inexpensive and high-performance television game device that can easily enhance the background effect.
