Abstract

Additive information for restoring the contour of an image is generated and embedded in the image data. The format of the additive information is determined beforehand. When a hard copy is produced, the additive information is extracted from received image data. The additive information is for example vary small characteristic points of a density different from the density assigned for image data and arranged inside the contour. The image data is restored according to the extracted additive information. The additive information can be generated for example from the code information for generating patterns such as control points data of an outline font. For a half-tone image, a plurality of density bands is assigned to the additive information. A read error is detected by comparing the restored image with the received image data.

Claims

1-15. -15. (Cancelled)

16. An image data processing apparatus adapted to receive code data and analyze said received code data to generate image data, said image data processing apparatus comprising:

an analyzer adapted to analyze said received code data to generate said image data;

a generator adapted to generate additional data based on said received code data; and

a synthesizer adapted to synthesize said additional data with said image data and to output said synthesized data.

17. An image data processing apparatus in accordance with claim 16,

wherein said generator obtains coordinate information from the received code data and generates additional data based on said coordinate information.

18. An image data processing apparatus as claimed in claim 17,

wherein said received code data is outline font data representing contours of characters.

19-33. -33. (Cancelled)

34. An image data processing method comprising the steps of:

receiving code data;

analyzing said received code data to generate said image data;

generating additional data based on said received code data; and

synthesizing said additional data with said image data and outputting said synthesized data.

35. An image data processing method in accordance with claim 34,

wherein said generating step includes:

obtaining coordinate information from said received code data and generating additional data based on said coordinate information.

36. An image data processing method as claimed in claim 35,

wherein said code data is outline font data representing character contours.
