Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an information processing system adapted to store into a memory the information whose range is designated in information displayed on the display screen of a display device.

2. Related Background Art

In general, there is known a system in which a range (position) of information such as image data or character data displayed on the display screen of a display device is designated or the information whose range is designated is erased from the display screen or synthesized on the display screen. Hitherto, a pointing device such as cursor key or mouse has been used as input means for designating a range of the information in such an information processing system.

However, in such a conventional information processing system, although the information whose range is designated by the pointing device can be automatically stored into a predetermined memory, it cannot be stored into an arbitrary one of a plurality of memories. Therefore, when printing or correcting the information on the screen, the information must be stored into the memory every time, causing a problem such that the input operations by the operator become complicated.

SUMMARY OF THE INVENTION

It is the first object of the invention to solve such problems and to provide an information processing system which can store the information on the display screen which is designated by a pointing device into an arbitrary memory device.

The second object of the invention is to provide an information processing system in which not only the position and range of the information displayed on the display screen by inputting a figure can be designated, but also a memory in which to store the information indicated in accordance with the input figure can be designated, and a storage form of the information indicating whether data is stored as a code, dots, or the like can be designated.

The third object of the invention is to provide an information processing system in which a range of information displayed on the display screen of a display device is designated by a figure pattern which is input from a tablet device and, the information whose range is designated is stored from a first memory into an area in a second memory which is decided in accordance with the shape of the figure pattern, thereby enabling various images to be synthesized.

DETAILED DESCRIPTION OF THE EMBODIMENTS

The present invention will be described in detail herein below with respect to an embodiment.

FIG. 1 shows a practical arrangement of an information processing system.

In FIG. 1, reference numeral 1 denotes a random access memory (RAM) used as second memory means to store information.

The RAM 1 has a font information area 1-1 to store font information which expresses character data in dot form, a code information area 1-2 in which the character data is expressed in numerical value form, and an area 1-3 to store other information.

Reference numeral 2 denotes a central processing unit (CPU) to process information. The CPU 2 functions as figure recognizing means.

Reference numeral 2-1 denotes a read only memory (ROM) in which control procedures shown in FIGS. 2 and 3 are stored.

A buffer 2-2 temporarily stores input/output information.

A keyboard 3 is provided to input character data.

Reference numeral 4 denotes a liquid crystal display (LCD) consisting of, e.g., 256.times.128 dots. The LCD 4 has a video RAM (VRAM) 4-1 as first memory means for storing image information to display.

Reference numeral 5 denotes a transparent tablet as input means which can input position information of 256.times.128 dots. A designating pen 5-1 for input is attached to the tablet 5. To prevent the display of the LCD 4 from being obstructed, each dot of the display screen of the transparent tablet 5 is made correspond to a respective dot of the LCD 4.

The character data input from the keyboard 3 is stored into the memory area 1-3 in the RAM by the CPU 2. Further, the input character data is converted into image data (font data) by the CPU 2 and sent to the VRAM 4-1. The information stored in the VRAM 4-1 is displayed on the display screen of the LCD 4.

The CPU 2 performs input and output control so as to display on the LCD 4 not only the input information but also the information stored in the memory area 1-3. If position information is input from the transparent tablet 5 while the character data is displayed on the LCD 4, the CPU 2 executes the control procedures of FIGS. 2 and 3.

In the control procedure of FIG. 2, the CPU 2 recognizes a figure of the input position information from the position information input from the tablet 5 (step S1).

In this embodiment, when the input position information forms a circle, the memory area 1-1 is designated. When it forms a square shape, the memory area 1-2 is designated. The figure recognition can be performed by using a well-known control program such as a vector recognizing method or the like.

As the result of the figure recognition in step S1, if the input position information from the tablet 5 forms, e.g., a circular figure, in order to store the display information of the LCD 4 enclosed in this circle, the CPU 2 stores a head address ADR.sub.1 in the font information memory area 1-1 into a register IX (steps S2 and S3).

When the CPU 2 decides that the input position information forms a square shape, the CPU 2 stores a head address ADR.sub.2 in the code information memory area 1-2 into the processing register IX (steps S4 and S5).

Next, the display information enclosed in the input figure is stored into the buffer 2-2 in the CPU 2. At this time, to fetch the display information in the form of font information, the dot information included in the input figure is taken out of the VRAM 4-1 of the LCD 4 by the CPU 2. The extracted dot information is stored into the address which is designated by the register IX in the font information memory area 1-1 (step S7).

Similarly, to fetch the character data in a form of code information, the CPU 2 extracts only the character data included in the square figure from the input character code data stored in the memory area 1-3. The CPU 2 stores the extracted character data into the address in the code information memory area 1-2 designated by the register IX.

After that, the CPU 2 executes information processes such as synthesis of images, edition of documents, and the like on the basis of the character data and image data stored in the memory areas 1-1 and 1-2.

In this embodiment, the explanation has been made with respect to the example in which a square and circular figures are input from the transparent tablet 5. However, the invention is not limited to those figures. It is also possible to constitute the system such that other various kinds of figure patterns such as triangles, parallelograms, hook-shaped parenthesis, circular parenthesis, and the like are predetermined, the memory area is selected in accordance with the input figure pattern, the insertion, deletion, or the like of the display image can be easily designated, and information can be easily read out of the memory and displayed in the area enclosed in the figure on the display screen.

On the other hand, to input not only figure information but also character data or the like from the transparent tablet, in order to distinguish "0" of the alphabetic character from the circular figure, it is sufficient to preset a discriminating pattern by adding a point in the circular figure or the like.

A desired memory area which is designated by the user is not limited to the range enclosed in the input figure. For example, in the case of storing information on a word unit basis, a triangle is set. In the case of storing information on a sentence unit basis, a square is set. In this manner, a figure shape is determined in correspondence to a length of sentence. It is also possible to designate so as to store the relevant word, sentence, or the like into the memory at the central position of the figure. In this case, in the process in step S6 shown in FIG. 2, the input figure including the word is designated by the center of the input figure or the word information in the area designated is stored into the buffer 2-2.

An explanation will now be made with respect to the case where, when a range of information to be stored into the RAM 1 is designated from the transparent tablet 5, a check is made to see if the user could designate desired data or not.

FIG. 3 shows an example of a control procedure to check whether data has been designated or not.

It is sufficient that this control procedure is executed between the processes in steps S6 and S7 in the control procedure shown in FIG. 2.

In FIG. 3, when a figure is input from the transparent tablet 5, the CPU 2 performs the reversal of white and black of the character data included in the figure. This white/black reversal can be realized by inverting the value of each bit of the image information in the range included in the figure in the image information stored in the VRAM 4-1, namely, by rewriting from "1" to "0" and from "0" to "1" (step S6-1).

Next, when the operator inputs a confirmation by using the designating pen 5-1, the processing routine is returned to step S7 shown in FIG. 2, and if a key to correct the range is input, step S1 follows to newly designate the range again (steps S6-2 and S6-3). To input that the designated range falls within a desired range, an arbitrary position on the tablet 5 in the input figure is input by using the designating pen. In the case of reinput of the designating range, the position out of the input figure is input by using the pen 5-1.

Although the embodiment has been described with respect to the example in which the LCD is used as the display device, the invention can be also applied to a CRT display device using a cathode ray tube.

Further, in the case where the CRT display device has a character generator to convert character code data into font data, there is no need to perform the font information conversion by the CPU.
