Then, the presence or absence of a player (observer) is determined, and if there is a player (when it comes), the process proceeds to step S33. If there is no player (when it leaves), the process proceeds to step S35.
- Step S33 when there is a player In the central light emitting element:! 8 Only the 0a and 18Ob are turned on, the other light emitting elements are turned off to make the viewing angle the narrowest, and a game image is displayed in step S34. Here, a left-eye image (first image) and a right-eye image (second image) are drawn, and a stereoscopic image is displayed.
- step S35 when no player is detected, all the light emitting elements 8100a to 8110d are turned on, the viewing angle is set to the widest state, and in step S36, display control is performed.
- the circuit 150 generates and displays an image in a standby state, and prompts a player passing in front of the gaming machine 1 to play a game.
- step S31 determines whether or not the detection level of the player detection sensor 271 has not changed from the previous time (when the player has not left).
- step S37 It proceeds to determine whether or not the player has operated the operation switch 160, and if the operation has been performed and an instruction to switch the viewing angle has been input, the process proceeds to step S38, and Thus, the viewing angle is controlled according to the pressed button 160 W to R. When the player does not operate the operation switch 160, the operation returns without changing the lighting state of the light source.
- the viewing angle can be adjusted according to the player's request, so that it is possible to select the viewing angle to the side that wants to show the details of the game, and to respond to the display environment according to the surrounding situation Can be done.
- step S35 all the light-emitting elements 810 & to 810d are turned on. However, all the light-emitting elements 8100a to (!) May be started to blink. Arousing to the player can be further emphasized.
- FIG. 14 shows a fourth embodiment, and an image display of the second embodiment
- the device 8 is used in a power navigation system, and the same components as those in the second embodiment are denoted by the same reference numerals, and redundant description is omitted.
- the bus 108 of the main control circuit 100 has a position measuring section 701 for measuring the position of the own vehicle based on a signal from the GPS antenna 700, and a storage device 700 for storing map information and the like. 2 is connected, and the CPU 101 arranges the current position of the vehicle on the map based on the calculated position of the own vehicle and the map information in the storage device 720 and displays the current position on the image display device 8.
- a tuner 704 that selects a desired channel based on a signal from a TV antenna and generates an image is connected to the path 108, and is configured to display a desired broadcast on the image display device 8. You.
- a parking switch 161 which detects the operating state of the parking brake of the vehicle, is connected to the input I / F 106 of the main control circuit 100.
- the parking switch 161 When is ON, indicates the parking state of the vehicle, and when 0FF indicates the traveling state.
- Fig. 15 shows an example of control in the car navigation system "5".
- step S41 it is determined whether the parking switch 161 is at 0 °.
- the process proceeds to step S42, and when the vehicle is traveling at 0FF, step S4 is performed. Proceed to 3.
- step S42 In the parked state S42, all the light-emitting elements 810a to 810d are lit, and in step S43 while driving, only the left-side light-emitting elements 810a and 810c Is turned on and the others are turned off.
- step S44 a TV image is drawn on the left image, and an image indicating the position of the vehicle is displayed on the right image. Therefore, the right-side light emitting elements 8110a and 810c are turned off during traveling, so that no image is displayed on the driver side, and the driver's inattentiveness can be suppressed.
- a TV image can always be displayed on the left image on the passenger seat side, and passengers can always enjoy the TV image.
- the information contents of the left and right images are different from each other, the information necessary for the driver and the passenger can be divided and displayed as appropriate while using the same display area.
