Abstract

PURPOSE:To effectively utilize a memory resource and to facilitate the addition and change of sizes with the acquisition system for character image data. CONSTITUTION:A memory means 1 for the character image data stores the character image data of the character code of the size to be a predetermined reference. A density converter 2 makes density conversion of the character code of the reference size to the character image data of an arbitrary size. A second information processor 4 requests the acquisition of the character image data and displays the acquired character image data. A first information processor 3 receives the request from the second information processor 4, reads the character image data of the character code of the reference size out of the memory means 1, makes the requested density conversion by using the density converter 2 and outputs the data to the second information processor.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for acquiring character image data in an electronic filing system or an image data editing system.

[0002]

2. Description of the Related Art Conventionally, this type of character image data acquisition method has a storage means for collecting and storing character image data of a required size corresponding to a series of character codes.
Prepare only the required number of sizes, and when character image data of a specific character code of a specific size is needed, use the storage means that stores the character image data of that size to store that character code. The method was to acquire character image data.

[0003]

In the above-described conventional character image data acquisition method, character image data for each size is stored in the storage means, and a specific character code of a specific size is acquired from the storage means. The required size must be predicted in advance. When a new size other than the prepared size is created, the character image data of that size must be created by the number of a series of character codes and stored in the storage means. -System resources are required in proportion to the number of character image data sizes. However, there are drawbacks such as being dependent on storage medium resources and being difficult to add and change sizes.

[0004]

The character image data acquisition method of the present invention comprises a storage means for collecting and storing character image data corresponding to a series of character codes of a size which is a reference for character image data of any size. A density conversion device for density converting a character code of the reference size to an arbitrary size, and an information processing for density conversion of an arbitrary character code using the density conversion device and the character code of the storage means and outputting to the output means It is composed of means.

[0005]

The present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a character image data acquisition system according to an embodiment of the present invention. 1 is a storage means for storing character image data which corresponds to a series of character codes and serves as a reference for character image data of any size, 2 is a density conversion device for density conversion to any size, 3, 4
Is a storage means 1 for the character image data and a density conversion device 2 respectively.
Although not shown, the first information processing device 3 has a central processing unit (CPU) and a memory, and the second information processing device 4 Has a CRT display device, a keyboard, a magnetic disk device, an optical disk device, and the like.

FIG. 2 is a block diagram showing the internal configuration of the above-mentioned first information processing apparatus 3. Reference numeral 21 denotes a system control unit that controls access to the character image data with respect to an I / O unit 22 for character image data, which will be described later, in response to a request to acquire the character image data from the second information processing device 4. In response to a request from the system control unit 21, a character image data I / O unit for reading / writing character image data to / from the character image data storage unit 1, the density conversion device 2, and the second information storage device 4. is there.

A method of acquiring character image data of an arbitrary size and displaying it on a CRT display in the above-mentioned configuration will be described. When a data display request is generated from the second information processing device 4, the system control unit 21 requests the character image data I / O unit 22 to read character image data of a size that is a reference for character image data of any size. I do. The I / O unit 22 of the character image data that has received the read request reads the character image data corresponding to the read request from the storage unit 1 of the character image data of the reference size. The system control unit 21 determines the requested size, and the character image data of the reference size read by the I / O unit 22 of the character image data is transferred to the density conversion device 2. I / O part 2
Make a request to 2. I / O of requested character image data
The unit 22 transfers the character image data of the reference size that has been read in advance to the density conversion device 2. The system control unit 21 sends the requested size to the density conversion device 2.
The density conversion device 2 density-converts character image data of a reference size to a requested size, and creates character image data of the requested size. The character image data of the requested size is transferred to the I / O unit 22 of the character image data. The system control unit 21 requests that the character image data transferred to the I / O unit 22 of the character image data be transferred to the second information processing device 4, and the I / O unit of the requested character image data is requested. 22 transfers the character image data of the requested size to the second information processing device 4 to perform CR.
It is displayed on the T display.

If the reference size of the character image data of any size matches the requested size, the density conversion processing of the character image data performed by the density conversion device 2 is not performed.

[0010]

As described above, according to the present invention, one storage unit for storing character image data of a size that serves as a reference for character image data of any size is prepared, and the character image data is density-converted by the density converter. Since I tried to create character image data of any size, I do not have to predict the required size in advance, and even when the size required newly increases, create character image data of that size, There is no need to store it in the storage means. -The number of character image data sizes is unlimited even if the system resources are constant. -The system resource is enough for one storage unit of character image data. As a result, the resource utilization of the storage means is economical, and the work of adding and changing the size becomes unnecessary.
