Abstract

PURPOSE:To make the processing content of the title processor distinguishable at a high speed by providing a sensor information table for storing the information indicating the processing content corresponding to the address information inputted from a pointing device and reading the sensor information table by using the address information. CONSTITUTION:When an address (X, Y) is inputted from a pointing device 1, a control section 5 accesses the address of a sensor information table 4 corresponding to the address (X, Y) and reads the content (code). Then the section 5 discriminates whether or not the read code is valid and, when the code is valid, performs processes in corresponding to the read code. When, for example, a certain icon is drawn in a displaying area of (2, 2) and (7, 7), the section 5 writes the prefixed code corresponding to the relevant icon at the address (0, 0) of the sensor information table corresponding to the address (0, 0) of a touch sensor. Thus an icon or drawing area, namely, the processing content can be discriminated instantaneously.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an information processing apparatus, such as a document creation/editing apparatus, a personal computer, or an image editing processing apparatus, equipped with a bitmap display device and a pointing device.

[Conventional technology]

In general, there are 5 document creation and editing devices, personal computers,
An information processing device such as an image editing processing device is equipped with a bitmap display device and a pointing device as a display device, and by pointing an icon displayed on the bitmap display device with the pointing device, processing indicated by the icon is performed. There are some that allow you to draw within the drawing area. It should be noted that the term "icon" refers to a device that indicates processing contents through a picture, and the term "pointing device" refers to a device that can indicate an arbitrary point on a display device, such as a mouse, a light pen, or a touch sensor.

In such an information processing device, the address information input from the pointing device is compared with the address information when the icon is drawn, and when the address information from the pointing device is within the area of the icon, the icon is The processing content (semantic information of the icon) shown in is performed.

[Problem to be solved by the invention]

However, it is not possible to determine the processing content by comparing the address information input from the pointing device and the address information when the icon is drawn in this way.
There is a problem in that as the number of icons increases, the time required to determine the processing content increases proportionally, resulting in poor responsiveness.

This invention has been made in view of the above points, and an object thereof is to make it possible to quickly determine the meaning information of an icon and the image area regardless of the number of icons or the number of pixels of a bitmap display device. shall be.

[Means to solve the problem]

In order to achieve the above object, the present invention provides an information processing apparatus equipped with a bitmap display device and a pointing device, which includes a sensor information table storing information indicating processing contents corresponding to address information input from the pointing device. It is something.

[For production]

The processing content can be determined by reading the sensor information table based on the address information input from the pointing device, and the processing content can be determined at high speed.

〔Example〕

Embodiments of the present invention will be specifically described below with reference to the drawings.

FIG. 1 is a functional block diagram showing an embodiment of the present invention.

The pointing device 1 is a device that can point to an arbitrary point on a display device, such as a mouse, a touch sensor, or a light pen, and an address (x, y) corresponding to the operation is input. The display section 2 is a pixel map CRT display device capable of displaying information bit by bit, and the one-stroke drawing section 3 controls drawing on the display section 2. The sensor information table 4 stores information indicating the processing content corresponding to the input of the pointing device 1.

The control unit 5 sends a drawing address (x, y) to the drawing unit 3.
is sent to display an icon or drawing window on the display unit 2, a predetermined code for the drawn icon or drawing window, etc. is written in the sensor information table 5, and the address (x, y
), the content (code) of the sensor information table 5 is read and output.

FIG. 2 is a block diagram showing the system configuration of this embodiment.

This information processing device includes a keyboard 11 as an input device.
and a touch sensor 12 having 8oxso touch keys as a pointing device (there is a sensor for each 8x8 display pixel), a bitmap display device 13 having a display area of 640x400 bits, a CPU, and a ROM.
, a microcomputer consisting of RAM, Ilo, etc., and a system control section 14 consisting of other mass storage devices, etc., and the storage device (memory) inside the system control section 14 is used as a sensor information table.

Next, the operation of this embodiment configured as described above will be explained with reference to FIG. 3 and subsequent figures.

First, the control section 5 of FIG. 1 displays a paint 22. as an icon on the display area 21 of the display section 2, for example, as shown in FIG. When displaying the line 232 circle 24, rectangle 25, or drawing area 26 as a window, predetermined codes corresponding to these icons and windows (this code may be a code that can be uniquely identified on the screen) is written in the sensor information table 4.

For example, as shown in FIG. 4, the display area of the paint 22 has a corresponding code of "P", the display area of the line 23 has a corresponding code of "L", and the display area of 1 yen 24 has a corresponding code of "P". "C" is written as the code to be displayed, r and 9J are written as the corresponding codes in the display area of the rectangle 25, "D" is written as the corresponding code in the display area of the drawing area 26, and invalid in other display areas. Write "0" corresponding to the area.

Here, writing the code to the sensor information table 4 is as follows:
When using the above-mentioned 80x50 touch sensor, the sensor at vs (X,
Y) to the address indicated by (XX50+Y+table start address).

As shown in FIG. 5, when the address (x, y) is input from the pointing device 1, the control unit 5 controls the address corresponding to the input address (x, y), in the above example ( Access the address of the sensor information table 4 indicated by XX50+Y+table start address), read its contents (code), determine whether the read code is valid or not, and if it is a valid code, read the read code. Perform the corresponding processing.

For example, when using the above-mentioned 640 x 400 bit map display device and 80 x 50 touch sensor, the 8 x 8 display pixels of the bit map display device correspond to one sensor of the touch sensor.
As shown in the figure, a certain icon is (2,2), (7,7
), the sensor information table (0°0) corresponding to the touch sensor address (0°0) is displayed.
, O), write a predetermined code corresponding to the icon.

Therefore, from the pointing device to the address (0, O
) is input, the code (corresponding to the processing content) corresponding to the icon can be obtained by reading the address (0, O) of the sensor information table.

In this way, it is possible to instantly determine which icon or drawing area it is, that is, determine the processing content.

Furthermore, when using the 80x50 touch sensor mentioned above, a sensor table with a capacity of 4 KB is sufficient, but when there is a one-to-one correspondence between display pixels and addresses, as in the case of a mouse, the correspondence relationship remains unchanged. If you create a table with The same effects as in the above embodiment can be obtained without increasing the capacity.

〔Effect of the invention〕

As described above, according to the present invention, since the sensor information table is provided that stores information indicating the processing content corresponding to the address information input from the pointing device, sensor information is By reading the contents of the table, processing contents such as the meaning information of the icon and the drawing area can be determined at high speed, and the responsiveness of the information processing apparatus is improved.
