Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a game device, and in particular, a method for capturing an image displayed on a display device using a video camera or the like, recognizing a certain image, and This invention relates to a playback device that allows users' reactions to be compared.

[Conventional technology]

In conventional television demoing devices, the player manipulates a joystick or the like with his hands or depresses a mad switch with his foot to perform dame according to a specific program. That is, the image displayed on the display of the TVDAME was dependent on the program recorded on the ROM cassette or disk used.

[Problem that the invention seeks to solve]

However, in the conventional TVDAME device, since the image displayed on the display depends on the program recorded on a ROM cassette or the like, there is a problem that the content of the play is standardized and lacks flexibility. Especially when children want to play with the main characters and villains of TV anime,
I couldn't play it until the corresponding software was released. Furthermore, even if compatible software is released, it is not possible to include many stories in one game program due to memory limitations, and children quickly get bored with it. The disadvantage of this method is that it requires multiple ROM cassettes, resulting in high costs.

Furthermore, the general TV Deme device does not have sufficient screen resolution ability, and there is the problem that children cannot enjoy the atmosphere of actually fighting the main character of a TV animation by watching the TV or Video Cheap Record playback screen. there were.

[Means for solving problems]

The present invention has been devised in view of the above problems, and includes a video input means for capturing an image displayed on a display device, and an image processing signal from the video input means to select a specific image from among the images. A pattern recognition processing means for recognizing at least one of hue, saturation, brightness, or shape, and comparing an output signal of the pattern recognition processing means with a user's operation signal, and outputting a comparison result signal. and a control means for detecting the correspondence between the image and the user's operation signal.

[Effect]

The present invention configured as described above captures an image displayed on a display device with a video input means, and from the image processing signal of the video input means, at least one of a specific hue, saturation, brightness, or shape is detected. The game device detects the correspondence between the screen and the user by recognizing the screen with a pattern recognition processing means and comparing the output signal of the pattern recognition processing means with the user's operation signal using the control means. .

〔Example〕

An embodiment of the present invention will be described based on the drawings. Reference numeral 1 denotes a video camera that captures an image displayed on a display device a. The video camera 1 is one of the video input means, and can be a video camera using an image pickup tube such as an ITV (industrial camera) or a vidicon tube, or a video camera using a solid-state image sensor such as a CCD (charge-coupled device). can do. It should be noted that the video camera 1 is not limited to the one exclusively used for the game device of this embodiment, but may also utilize the line output of a camera-integrated video camera that has recently become popular.

That is, in this specification, the video input means is sufficient as long as it is a means for inputting an image processing signal converted into an electrical signal. A gage digital camera using an optical RAM can also be used, but it is of course necessary to use a suitable optical lens as in the video camera 1. 2 is an input processing unit, and a video camera 1
It processes the analog output of the image processing signal, and performs noise processing, etc. Reference numeral 3 denotes a high-speed AD converter, which converts the output signal of the input processing section 2 into a digital signal. Reference numeral 4 designates a first lookup table, which is one of the digital processes for reliably extracting image features. That is, the output signal is manipulated according to a data conversion code table. Lookup table operations allow data to be binarized, image contrast to be adjusted, and the like. A frame buffer 5 stores the digital output of the high-speed A-D converter 3, and can use a 512×512×8-bit image memory IC.

In this embodiment, #1 lookup table 4
The digital signal processed by the 7-frame buffer 5
is memorized. A second lookup table 6 is used together with the first lookup table 4 to ensure feature extraction of the image. Note that when performing color image processing, the R-
Three input processing units 2, 2 each receive G-B output signals.
．． 2, high speed A-D converter 3, 3, 3, first lookup table 4, 4, 4 and 7 frame φ buffer 5,
It is preferable that the second lookup table 6.5,5 and the second lookup table 6.6,6 be processed independently. Note that if a two-dimensional gauging camera such as an optical RAM is employed as the video input means, the high-speed AD converter 3 is unnecessary. This is because these elements operate in the same way as 1-bit AD conversion, so they can be understood as a camera with a built-in AD converter. 7 is a pattern recognition processing means, which recognizes a specific hue,
The image processing signal includes a video signal for creating an image, a color signal for adding color to the image, and an image signal in order. It consists of a synchronization signal for arranging the colors.Generally, a color signal has information on hue and saturation, and the hue is 3.58.
It is expressed by the phase of the color signal with respect to the MHz reference burst, and the saturation is expressed by its amplitude. Furthermore, the luminance signal is a signal representing brightness, and is represented by its DC component. Therefore, in the case of a black and white television camera or the like, the image processing signal is composed of a luminance signal and a synchronization signal. The pattern recognition processing means 7 performs a pattern comparison with reference pattern data from the signal or the shape determined from the signal. That is, the pattern recognition processing means 7 stores an electrical signal corresponding to at least one of a specific hue, saturation, brightness, or shape as reference pattern data,
This data is compared with the image processing signal. Note that as the pattern recognition method, an appropriate method such as a superimposition method or a feature extraction method can be adopted. Note that prior to pattern recognition, it is desirable to perform preprocessing such as filtering and differential calculation. For example, a blurred image can be enhanced by smoothing the image using a low-pass filter or by adding or subtracting the result value after differential calculation processing and the original image. 8 is a control means which compares the output signal of the pattern recognition processing means 7 with the operation signal of the user (player) and outputs the result of this comparison as an electric signal. Here, the user's operation signal may be inputted from a controller such as a joystick, or further may be inputted from a switch formed on the toy gun 9. That is, in this specification, the user's operation signal is sufficient as long as it is an electrical signal generated in response to the user's intention.

Furthermore, the comparison between the output signal of the pattern recognition processing means 7 and the user's operation signal may be based on the time coincidence of these two electrical signals, and also the coincidence of analog quantities such as voltage, pulse frequency or It may also be a duty ratio or the like. In other words, it is sufficient to be able to compare both electrical signals based on some standard. The control means 8 outputs the above-mentioned comparison result signal and drives at least one of a low frequency oscillation circuit such as a buzzer and a visible light generation circuit such as a lamp. It is also possible to output this comparison result signal to another TVDAME device.

Next, to explain the case where this embodiment is applied to a shooting game, first, during the time period when a specific TV anime is being broadcast,
Activate display a to display the broadcast content. Then, a ROM capsule or the like in which the shapes and colors of some or all of the villains among the characters appearing in this television animation are stored is connected to the pattern recognition processing means 7.

Further, a toy gun 9 having a switch formed on its trigger is connected to the control means 8. The player, while following the story of the television program displayed on the display a, pulls the trigger of the toy gun 9 when a villain appears. The pattern recognition processing means 7 recognizes the villain appearing on the display a and sends an output signal to the control means 8. The control means 8 compares the output signal of the pattern recognition processing means 7 and the operation signal from the toy gun 9, and outputs a comparison result signal when a temporal coincidence is determined. This comparison result signal causes the low frequency oscillation circuit 1 to
0 is driven and a breaking sound is generated. Furthermore, the lamp 11 provided on the goggles worn by the user blinks, giving the user the feeling of having repelled the villain. This TV anime is not only broadcast on TV, but also on VTR.
It may also be a recorded matter such as. The optical lens used in the television camera 1 is preferably a zoom lens, and it is necessary to photograph the display surface as large as possible from an appropriate position. Further, in this embodiment, the reference pattern data is inputted using a ROM capsule, but it is also possible to input and store the villain as a still image from a VTR or the like and use this data as the reference pattern data.

Note that it is desirable to provide means for tracking the synchronization signal of the VTR with the synchronization signal of the television camera 1.

By attaching a color filter of substantially the same color as a specific color to the optical lens of the video camera 1, an extremely inexpensive recognition device can be provided. Furthermore, it is also possible to perform shooting by emitting a laser beam or the like from the toy gun 9 toward the display a and photographing the point of impact on the display a with the video camera 1. Note that the images displayed on display a are not limited to television animation.

〔effect〕

The present invention configured as described above captures an image displayed on a display device using a video input means, and recognizes a specific hue, shape, etc. from the image processing signal of the video input means using a pattern recognition processing means. By comparing the output signal of this pattern recognition processing means with the user's operation signal by the control means, the correspondence between the screen and the user is detected, so that the image displayed on the display is recorded in a ROM cassette, etc. This has the advantage that anime programs etc. broadcast on television can be used without depending on the programs currently being played.

For this reason, children can enjoy the atmosphere of playing with the main characters of a real TV animation, and can enjoy many stories, which has the effect of never getting boring. Furthermore, since the game can be played using television broadcasts, etc. without having to collect a lot of software, the cost is low, which is an outstanding effect.
