Problems solved by technology

[0011] Therefore, since the scrolling rates are all the same, there is a problem in the above-mentioned prior art that when a display device having a low display processing rate such as a liquid crystal display is used, the image cannot be moved to the specified position very quickly. Get the directionality of the movement and confuse the user
[0012] In addition, the related art has another problem that when the scroll speed increases, it is difficult to confirm a scroll amount, and in order to confirm the scroll amount, the scroll must be released

Abstract

There is provided a scroll controller which solves a problem that in scrolling an image at coordinates specified by a pen or the like to specific coordinates (e.g., the center), it is unable in a display such as a liquid crystal display having a slow display reaction speed to grasp the state of movement when a scroll quantity (scroll speed) per unit time is fast. The scroll controller calculates a difference between prefixed coordinates and the coordinate position specified by a position specifying device and on the basis of the calculation result, controls so that not only stepwise scroll quantities are obtained, but also scroll quantities in starting and ending of the scroll are different from that in the other time of the scroll.

Description

technical field [0001] The present invention relates to a scroll controller that converts data into a visually displayed image and visually displays the image, suitable for implementation in personal computers and small electronic devices. Background technique [0002] A so-called scroll controller in a small electronic device is a type of scroll controller, for example, disclosed in Japanese Unexamined Patent Publication No. JP-A9-69037 (1977), which is set by a movement direction and a movement amount set by dots. A technique for implementing a scrolling operation. [0003] Figure 13A with 13B are diagrams and diagrams illustrating scroll operations of the related art. Figure 13A The outer frame 83 in the figure represents the edge of the scrolling area of ​​the display screen of a display device, that is, the edge of a visible display area where the image scrolling operation is performed. [0004] In the center of the scrolling area there is a reference point 85 . De...
