FIG. 4 is a flowchart showing processing in the document editing program 22 of the character display device according to the embodiment for realizing the present invention. This flowchart is started after the power of the character display device is turned on and initialization processing is performed by the initialization program 21.

First, document data is input from any of the keyboard 5, the communication device 7, and the storage medium input / output device 10,
It is stored in the document data storage area 31 (step S41),
A process for allowing the user to select a display mode is performed (step S42). In display mode, each character of the document is 16x16
There are a standard display mode in which dots are displayed, an upper case display mode in which 24 × 24 dots are displayed, and a lower case display mode in which 12 × 12 dots are displayed. In addition, there is a mode for enlarging a specific character among characters specified by the cursor (enlarged display mode) and a mode for not enlarging all characters (non-enlarged display mode). The user selects either. The selected mode is stored in the display mode storage area 33.

In step S41, the document data storage area 31
Is stored as character image data having a size based on the display mode selected in step S42.
It is taken out from the character image data storage area 321 and displayed on the display device 4 (step S43), and the cursor is set at a predetermined position (initially at the upper left of the display screen) and displayed (step S44), and the timer 8 is initialized. To start timer counting (step S45).

Next, it is determined whether an instruction to move the cursor has been made from the keyboard 5 (step S46). If an instruction to move the cursor has been made, the process returns to step S44 to move the cursor position in the designated direction. If no move instruction has been given, it is determined whether there is another instruction from the keyboard 5, for example, a document editing end instruction, a document print instruction, and the like (step S47). If there is another instruction in step S47, it is determined whether an instruction to end the document editing has been issued from the keyboard 5 (step S48). If the instruction has been made, the processing of the character display device ends. If the instruction has not been made, other processing, for example, a document printing processing, is performed (step S49), and the process returns to step S44.

On the other hand, if there is no other instruction in step S47, it is determined in step S42 whether the enlarged display mode or the non-enlarged display mode is selected by referring to the display mode storage area 33 (step S42). S5
0), if the non-enlarged display mode is selected, step S
Returning to 46, if the enlarged display mode is selected, it is determined whether the timer value of the timer 8 has exceeded a predetermined value, for example, 3 seconds (step S51), and if not, the process returns to step S46. If it exceeds, it is determined whether or not to enlarge the character according to the character at the current cursor position and the current display mode (step S52). If not, the process returns to step S46. When the display is enlarged, the process proceeds to step S53. The details of the character enlargement determination process in step S52 will be described later.

In step S53, a character enlarged display area is secured near the cursor position (a position separated by about one or two characters from the cursor position), and the character at the cursor position is enlarged and displayed there. When the cursor position is at the upper end of the display device, the enlarged character display area is located below the cursor position,
When the cursor position is at the lower end of the display device, the enlarged character display area is above the cursor position, and when the cursor position is at the left end of the display device, the enlarged character display area is on the right side of the cursor position, and the cursor position is on the display device. If it is on the far right,
The enlarged character display area may be displayed on the left side of the cursor position. FIG. 5 is an example of a display screen in which characters are enlarged and displayed. In FIG. 5, reference numeral 51 denotes a document display area, 52 denotes a function key display area, 53 denotes a cursor, and 54 denotes an enlarged character display area. The character enlarged display area 54 is displayed near the cursor only when characters are enlarged and displayed, and usually a document is displayed.

Next, it is determined whether or not a cursor movement instruction has been issued from the keyboard 5 (step S54). If no movement instruction has been given, the process waits as it is. If a movement instruction has been given, the character displayed in step S53 is displayed. The enlarged area 54 is deleted (step S55), the display returns to the original document display, and the process returns to step S44.

FIG. 6 is a flowchart showing details of the character enlargement determination process (step S52).

First, the character at the current cursor position is obtained (step S61), and any or all of the obtained character's complexity level, number of strokes, and dot density are read from the complexity data storage area 322 (see FIG. 2). Acquisition (Step S
62) Further, the criterion data corresponding to the current display mode is obtained from the criterion data storage area 34 (see FIG. 3) (step S63).

Next, it is determined whether or not the complexity level obtained in step S62 is equal to or higher than the criterion obtained in step S63 (step S64). If it does not exceed the criterion, it is determined whether the number of strokes obtained in step S62 is equal to or greater than the criterion obtained in step S63 (step S65).
The process ends as ES. If the dot density does not exceed the judgment criterion, the dot density acquired in step S62 is equal to that in step S6.
It is determined whether the criterion is equal to or greater than the criterion obtained in step 3 (step S
66) If it is equal to or greater than the determination criterion, the character enlargement determination is made as YES and the process is terminated. If it does not exceed the criterion, the character enlargement determination is made NO and the process is terminated.

In the above description, the character designated by the cursor is enlarged and displayed. However, the character indicated by the mouse 6 (the character indicated by the mouse pointer) is enlarged and displayed. Is also good. This means that the "cursor" in the flowchart is replaced with the "mouse pointer".
Alternatively, this can be realized by replacing “keyboard 5” with “mouse 6”.

The contents of the embodiments described above are not limited to the contents described above unless the gist of the present invention is changed.

In the second, third and fourth aspects of the present invention,
Characters are enlarged and displayed only when the designated character is complicated (for example, when the dot density is high or the number of strokes is large). Therefore, only necessary characters are enlarged and unnecessary characters are not enlarged.

According to the fifth aspect of the present invention, necessary characters are changed in order to change a criterion for determining whether or not to enlarge characters according to the current display mode (standard display mode, lowercase display mode, uppercase display mode, etc.). Only the characters are enlarged and unnecessary characters are not enlarged.

In the sixth aspect, when the cursor or the mouse cursor is moved after the enlarged display, the enlarged display is automatically erased, so that there is no need to perform a special operation and the operation is not complicated.

In the seventh aspect, the character is enlarged and displayed only when the cursor or the mouse pointer has not been moved for a certain period of time. Therefore, the character can be enlarged and displayed when the cursor is not moved and the enlarged display is unnecessary. Absent. Also,
Since there is no need to give a magnified display instruction when performing the magnified display, the operation does not become complicated.
