504 Dot image into 21x21 external character sections (
The configuration is such that it can be registered in a combination custom character area consisting of 24 x 24 dots per section, saved in a storage file such as a custom character floppy disk, and read into the document when inputting or editing the document.

One type of image correction function in a personal word processor that has an image storage function based on a combination of external characters is - brushstroke correction.

This handwriting correction is done by placing the crosshair cursor on the point you want to correct and holding down a specific function key and cursor key, but as mentioned earlier, the image data is a 21x2' single composition. Since it is composed of crossed characters and displayed at a high density of 504 x 504 dots, each dot on the screen is very small, and the movement of the characters to the cross on the screen is also slow. Therefore, there was a problem in that correction work was difficult and required a lot of time.

(Problems to be Solved by the Invention) As described above, in conventional personal word processors that have an image storage function based on combinations of external characters, each dot on the screen is extremely small, and - operability for correcting handwriting is The problem was that it was bad.

The present invention has been made in view of the above-mentioned circumstances, and has a function of cutting out a part of the image stored in the combination custom character block in units of predetermined custom character blocks without changing the shape, and enlarging and displaying the image. - It is an object of the present invention to provide a document creation device that can efficiently and smoothly correct handwriting in a short time.
