[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display control device suitable for use in, for example, game machines.

[0002]

2. Description of the Related Art In a game machine such as a family computer (trademark), by holding an operating portion by hand and operating a switch provided on the operating portion, a predetermined command is given and displayed on a screen. It is designed to change the image that is present. The user can input a predetermined command by operating a predetermined switch at a predetermined timing.

However, in the conventional device, since the predetermined command is input by operating the switch in this way, the command that can be input is limited and the change can be made. There was a problem that a rich command could not be input. As a result, the screen changes are monotonous, and there is a problem that it is not possible to enjoy a variety of games.

The present invention has been made in view of such a situation, and makes it possible to perform more varied input.

[0005]

A display control device of the present invention comprises an output means for outputting an image signal, an operating means capable of taking an arbitrary posture, and a detecting means for detecting an inclination of the operating means. And a control means for controlling the image signal output from the output means in response to the output of the detection means.

The detecting means can be configured to detect at least one of the inclination with respect to the horizontal line and the inclination about the vertical axis.

[0007]

In the display controller having the above structure, when the operating means is tilted, the detecting means detects the tilt, and the image signal output from the output means is controlled in accordance with the tilt detected by the detecting means. Controlled by means. As a result, a more varied display can be executed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram showing the configuration of an embodiment of a game device to which the display control device of the present invention is applied. A predetermined image signal is recorded on the disc 1. The spindle motor 2 rotates this disc 1. The pickup 3 reproduces the signal recorded on the disc 1 and outputs it to the signal processing unit 6 via the amplifier 5. The signal processing section 6 processes the input image signal and stores it in the RAM 7. RA

These outputs are output to the CPU 4 by the code 11 via the amplifiers 24, 26 and 28, respectively. In addition, by operating the key switch 22 including a plurality of keys,
A predetermined command can be input to the CPU 4.

FIG. 2 shows a configuration example of the angle sensor 23 (or 25). In the case of this embodiment, the fixing portion 31 is fixed to a predetermined position of the operating device 21. A rod-shaped rotary shaft 32 is attached to the fixed portion 31, and a weight 33 is attached to the tip thereof.

FIG. 3 shows the operating principle of this angle sensor. As shown in FIG. 3A, for example, when the operation device 21 is tilted to the right, the body 31 is tilted as indicated by the solid line in the figure in correspondence with the tilt. However, the weight 3
3 is always oriented vertically. Therefore, a positive voltage as shown in FIG. 3B is generated in correspondence with the angle θ between the horizontal direction shown by the broken line in the figure and the position shown by the solid line.

On the other hand, when the operating device 21 is tilted to the left as shown in FIG. 3 (c), a negative voltage is generated as shown in FIG. 3 (d). Therefore, the slope is detected from this voltage.
