However, in the code image data conversion method used in conventional facsimile machines and word processors, in the case of method Because the ability to express
There has been a problem in that the size of the output characters changes in response to changes in the expressive ability of the pixel density of the other party. For example, even if the pixel density is set to be 200 dpi x 200 dpi for easy reading, if the pixel density of the destination terminal is 400 dpi x 400 dpi, the output characters will be 1/4 the size. It becomes very unpleasant to read.

In addition, in the case of method (■) above, many methods have been devised to change the size of characters beautifully through thinning processing and OR processing, but in all of these methods, the output characters are not the same as the original font data. However, it is inevitable that characters will be output with some degree of distortion.

In addition, in the case of method (■) above, characters of any size can be beautifully developed into image data, so it takes a certain amount of time to develop the image data, which is required when creating image data in advance using a word processor or the like and outputting it to a facsimile machine. If there is enough time, the current amount is an effective method, but there is a problem that it cannot be used when the time required to develop image data such as output to a facsimile machine is short.

(Purpose of the Invention) Therefore, the present invention selects various font data according to the output character size specified by the host device, and transfers the selected font data to a destination terminal to which the host device outputs image data. By generating image data by changing the magnification at a predetermined magnification based on the pixel density information specified by It is an object of the present invention to provide a code image data converting device that allows a device that outputs document data to have a function of outputting beautiful character image data in a short time.

(Means for Solving the Problem) In order to achieve the above object, a code image data conversion device that generates and outputs image data corresponding to character code data input from a host device generates the image data. font data selection means for selecting the font data file based on the output character size specified by the host device; and the host device outputs the image data. The present invention is characterized in that image data generation means generates image data by scaling the selected font data at a predetermined magnification based on pixel density information specified by the destination terminal.

In this embodiment, the magnification is set for each of the font data files CG1 to CGn to be an integer multiple.

The font data table 4 stores a plurality of font data files CGI to CGn having different numbers of dots.
For example, the number of dots is 24x24dots,
It is assumed that the font data has a size of 32x32dots, 40x40dots, etc.

The image data generation section 5 generates character image data using the character code data output from the host device 11 and the font data and magnification data output from the font data magnification selection section 2 and converts the image data into the image data synthesis device 2.
Output to 1.

The host device 11 also has a communication function for performing data communication between a data memory 12 that stores character code data input from a keyboard (not shown) and an external communication terminal. The pixel density information shown in the terminal function information and the output character size specification entered manually by the operator are outputted to the font data magnification selection section 2, and the character code data entered manually is outputted to the font data magnification selection section 2. is output to the image data generation section 5. Further, the host device 11 sends the combined image data output from the image data combining device 21 to the facsimile device 25.

The image data generation section 5 generates character image data corresponding to the character code data according to the font data and font magnification instructions transferred from the font data magnification selection section 2 (step P4), and converts the header information of the generated character image data into an image. It is output to the data synthesis device 21 and ends (step P5).

As described above, in this embodiment, character code data is generated by enlarging the font data selected based on the pixel density information of the output destination terminal at an integer magnification. Because the processing is not complicated, and because the scaling factor of the font data is set to an integer multiple, beautiful character image data can be generated in a short time. Therefore, it is possible to cope with cases where it is required to generate image data in a relatively short time, such as when outputting header information.
