Abstract

There is disclosed a display apparatus capable of displaying code data and image data. Both data are displayed in a different manner, for example in different colors, in order to enable the user to distinguish these data.

Claims

1. A display apparatus comprising:

a memory for storing data consisting of a mixture, on one page, of one or more areas consisting of code data such as characters or symbols, and one or more areas consisting of image data, the data being divided into respective blocks in accordance with the kinds of data;

conversion means for reading the blocks of data stored in the memory and discriminating between the code data block and the image data block and converting the read blocks of data into dot data in response to the discrimination; and

display means for displaying the converted dot data,

wherein said display means displays the dot data converted from the code data block and the dot data converted from the image data block in a manner which distinguishes the dot data converted from the code data block from the dot data converted from the image data block without changing an original state of the mixture.

2. An apparatus according to claim 1, wherein the image data is compressed data and said conversion means expands the compressed data and then converts it into the dot data.

3. An apparatus according to claim 1, wherein said conversion means includes a character generator for converting each of the code data into corresponding font data.

4. An apparatus according to claim 1, wherein each of the blocks is provided with identification information indicating whether the block is a code data block or image data block.

5. An apparatus according to claim 1, further comprising means for communicating the data.

6. An apparatus according to claim 5, wherein said communication means transmits the data stored in the memory.

7. An apparatus according to claim 5, wherein data received by said communication means is stored in said memory.

8. An apparatus according to claim 1, further comprising means for editing the data stored in the memory.

9. A data communication apparatus comprising:

code data input means for inputting code data such as characters and symbols;

reader means for reading image data;

editing means for editing the code data and the image data, and for forming a mixture of data comprising one or more area consisting of the code data and one or more areas consisting of the image data;

communication means for communicating the mixture of data;

memory means for storing the mixture of data edited by said editing means or the mixture of data received by said communication means;

conversion means for reading, area by area, the mixture of data stored in said memory means and converting the read mixture of data into dot data; and

display means for displaying the converted dot data,

wherein said display means displays the dot data converted from the code data area and the dot data converted from the image data area in a manner which distinguishes the dot data converted from the code data area from the dot data converted from the image data area without changing an original state of the mixture.

10. An apparatus according to claim 9, wherein said display means separately displays the dot data converted from the code data and the dot data converted from the image data with respectively different background colors.

11. An apparatus according to claim 9, wherein the mixture of data stored in said memory means is divided into blocks in accordance with the kinds of data and each of the blocks is provided with identification information indicating the kind of data contained therein.

12. An apparatus according to claim 9, wherein said conversion means reads the mixture of data stord in said memory means block by block, discriminates whether data in each block is code data or image data, and converts each block data into the dot data in accordance with the discrimination.

13. An apparatus according to claim 9, wherein the image data is compressed data and said conversion means expands the compressed data and then converts it into the dot data.

14. An apparatus according to claim 9, wherein said conversion means includes a character generator for converting each of the code data into corresponding font data.

15. A display apparatus comprising:

a source for generating data consisting of a mixture, on one page, of one or more areas consisting of code data, such as characters or symbols, and one or more areas consisting of image data;

conversion means for converting the mixture of data into dot data area by area;

display means for displaying the converted data; and

control means for controlling said display means such that the dot data from the code data area and the dot data from the image data can be displayed in a manner which distinguishes the dot data from the code data area from the dot area from the image data area without changing an original state of the mixture.

16. An apparatus according to claim 15, wherein the code data area and the image data area are displayed with respectively different background colors.

17. An apparatus according to claim 15, wherein said source includes a memory for storing the data consisting of the mixture and reads the data stored in the memory.
