Abstract

A server is connected to an Ethernet port via a network and is further connected to a copier via video interface ports. The server is capable of subjecting image data read in by the copier or obtained from the network to processing for character recognition, coding and translation by a character recognition circuit, image coding/decoding circuit and translating circuit. Furthermore, image data is capable of being generated by a page-description-language interpreter based upon data, which is in the format of page description language, received from the network. Conversely, a character in the image data is capable of being recognized, coded and converted into page description language so that the amount of data sent to the network can be reduced.

designation means for designating areas in which a character image is recognized in the pre-inputted image;

wherein said recognition means recognizes a character image in the area designated by said designation means.

11. The apparatus according to claim 10, wherein said pre-input means thins the original image and displays the thinned image.

12. The apparatus according to claim 1, further comprising translation means for translating sentences which consist of the recognized character codes to target sentences which consist of target character codes;

wherein said control means controls said communication means to send the translated character codes to said other apparatus to which the page description language corresponds.

13. An apparatus according to claim 1, wherein said input means inputs the original image by an image scanner.

14. An apparatus according to claim 1 further comprising:

a printer engine which prints an image based upon the character codes described by the page description language data received via said communication means.

15. The apparatus according to claim 1 further comprising a memory for storing the code date converted by said coding means.

16. The apparatus according to claim 15, wherein said control means controls said communication means to send the code data stored in said memory.

17. The apparatus according to claim 1, wherein said character recognition means recognizes direction of the character image, and said coding means converts the character code, the position from which the character image is extracted and the direction of the character image into code data.

18. An image processing method for an apparatus connected via communication network, comprising the steps of:

inputting an original image including a character image;

extracting the character image from the original image;

recognizing extracted character image and converting the character image into a character code;

converting the character code and a position from which the character image is extracted into code data, described in a page description language which is interpretable by another apparatus connected to the network, so that a character image represented by the character code is outputted at a position corresponding to the position from which the character image is extracted; and
