DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
This invention relates to an operating device and an image processing system using same. More particularly, this invention is concerned with an operating device (joystick) with which the function is extendable for an image processing apparatus such as a personal computer, a video game machine, and so on, to enable transmission and reception of any data.
BACKGROUND AND SUMMARY OF THE INVENTION
Conventional joysticks are structured to detect in which direction and to what degree an operating member thereof is inclined. The "home" or neutral position to which the operating member returns when not operated by an operator is the origin point from which inclination of the operating member is measured. Because the origin point is fixed and not alterable by a user, the user cannot freely modify the location of the origin point.
It is therefore an object of the present invention to provide an operating device in which errors incurred through mass production can readily corrected and the origin point of the operating device can be determined and modified freely by an user.
It is another object of the present invention to provide an image processing system using such an operating device.
An operating device is connected during use to an image processing apparatus (10) that generates image data to be displayed on a display according to a program, to supply a signal for providing variation to the image data to be generated by an image processing apparatus, the operating device comprising: an operating member (451), a rotating member (457, 467), a rotation detecting means (459, 469), a count means (444X, 444Y), a reset signal generating means (442, 443, 447, 448), and a transfer means (442, 445, 43).
The operating member is supported to be tilt-operated by an operator so as to incline within a predetermined range and rest, when not operated by the operator, at a predetermined neutral position. The rotating member is arranged for rotation depending upon an inclination amount of the operating member. The rotation detecting means detect a rotational state of the rotating member. The count means varies a count value thereof depending on a rotational amount of the rotating member detected by the rotation detecting means. The reset signal generating means generates a reset signal to reset the count value of the count means. The transfer means transfers the count value counted by the count means to the image processing apparatus.
An image processing system includes an image processing apparatus for generating image data to be displayed on a display according to a program, and an operating device for connecting during use to the image processing apparatus so as to supply a signal for the image data to be generated by the image processing apparatus. The image processing apparatus (10) includes a program memory (20), a first receiving means (173), a central processing means (11), a first transmitting means (172), and an image signal generating means (16), and wherein the operating device (40) includes an operating member (451), a rotating member (457, 467), a rotation detecting means (459, 469), a count means (444X, 444Y), a reset signal generating means (442, 443, 447, 448), a second receiving means (173), a transfer means (171), and a second transmitting means (172).
The program memory is stored with a program for image processing. The first receiving means receives data generated by the operating device. The central processing means generates command data according to the program stored in the program memory, and generating image data depending upon the program and the data received by the first receiving means. The first transmitting means transmits the command data generated by the central processing means to the operating device. The image signal generating means generates an image signal for displaying an image on the display depending upon the image data from the central processing means. The operating member is supported to be tilt-operated to be inclined within a predetermined range by the ope
