Image display device

Abstract

Various commands and data are input to an image display device via an input block. Part or whole of basic image data formed of a dot matrix is stored in a basic image data storage device of the image display device. A portion of the basic image data in a display range is converted to display image data to display the display image data on the display screen, in response to a corresponding one of the various commands input by the input. From the input block, there are input a start command for starting an automatic scroll process for automatically continuously shifting the display range in a scrolling manner in a predetermined one of upward, downward, leftward and rightward directions on the basic image data, and a proportion change command for changing a proportion between the size of the display image data and the size of the basic image data, at or before the start of the automatic scroll process or during the automatic scroll process. The automatic scroll process is started in response to the start command, and the display image data is changed in response to the proportion change command and according thereto to thereby display resulting display image data on the display screen.

Description

technical field [0001] The present invention relates to an image display device for an information processing device, and more particularly to an image display device for a display screen having a small image scale as in an image display device in a small and inexpensive information processing device such as a tape printing device. A display device for displaying. Background technique [0002] In the prior art, in such a small and cheap information processing device, since the scale of processing image data in the device is smaller than that of a general personal computer, the display image displayed on the display device The image is smaller, and recently, with the advancement of technology, there have been small, inexpensive information processing devices that simultaneously process expanded image data, and it is required that a display device capable of displaying a larger-scale image is required. [0003] On the other hand, the size and number of dots of the display scr...

Problems solved by technology

[0005] On the other hand, in the above-mentioned tape printing device, there is a tendency to use a wide paper tape as a printing object, and the basic image data corresponding to the wide paper tape is reduced to about 512 dots and 1024 dots for display. Therefore, the content and layout of each unit image cannot be grasped (refer to Figure 45A , 45B )

It can be expected that such a problem will become more and more prominent as the width of the tape becomes wider, that is, as the scale of image data that can be printed becomes larger and more diverse.

In addition to the tape printing device, for example, in a small-sized seal making device, it can be expected that the image display device of other small and cheap information processing devices for viewing image data of a seal with a relatively large seal surface, etc. , with the possibility of common subjects
