Abstract

An integrated image recorder (100) receives first pictorial image data from an input scanner (300) and stores the same in an image disk (150). The pixels of the picture are skipped at a predetermined rate to obtain second pictorial image data having a lower resolution. The second pictorial image data is transmitted to a front end processor (201, 202) and employed in editing/designing of a page as an integrated image. The integrated image is represented in a page description language and is delivered to the integrated image recorder. The integrated image recorder is operable to read out the first pictorial image data from the image disk and to convert the integrated image into a bit map using the first pictorial image. The integrated image is then delivered to an output scanner (190) and is recorded on a recording medium.

Claims

1. A method of generating an integrated image including images of a character, a graphic and a picture and then recording said integrated image with an image recording means provided in an integrated image recorder, comprising the steps of:

(a) reading an image of a picture to obtain first pictorial image data representing said image of said picture in a first resolution and storing said first pictorial image data in memory means provided in the integrated image recorder;

(b) reducing the amount of said first pictorial image data to obtain second pictorial image data representing said image of said picture in a second resolution lower than that of said first resolution and then storing said second pictorial image data in said memory means;

(c) operating a front end processor coupled to said integrated image recorder to designate a character and a graphic to be integrated with said image of said picture on an image plane corresponding to a page;

(d) transferring said second pictorial image data from said memory means to said front end processor;

(e) operating said front end processor to determine a layout of said picture, said character and said graphic on said image plane, thereby obtaining a page description program for the integrated image;

(f) transferring said page description program to said integrated image recorder;

(g) reading out said first pictorial image data from said memory means;

(h) converting said integrated image into a bit-mapped image data while using said first pictorial image data for a pictorial part of said integrated image to thereby obtain in a buffer memory an integrated image data representing the integrated image; and

(i) enabling said image recording means to record said integrated image on a recording medium as a function of said bit-mapped image data,

wherein the step (b) comprises the step of;

(b-1) skipping over pixels of said first pictorial image data at a predetermined rate to obtain said second pictorial image data, wherein

the step (d) comprises the steps of;

(d-1) directing said integrated image recorder to transfer said second pictorial image data to said front end processor;

(d-2) reading out said second pictorial image data from said memory means; and

(d-3) transferring said second pictorial image data to said front end processor.

2. The method of claim 1, wherein

the step (d-3) comprises the steps of:

(d-4) transferring to said front end processor said second pictorial image data together with first accompanying data defining;

numbers of pixels forming said second pictorial image data in two directions defined on said picture.

3. The method of claim 2, wherein

said first accompanying data further includes:

a file name of said second pictorial image data;

a number of bits representing said second pictorial image data per pixel; and

data designating whether said second pictorial image is monochrome or color.

4. The method of claim 1, wherein

the step (e) comprises the step of:

(e-1) determining a trimming area on said image of said picture represented by said second pictorial image data.

5. The method of claim 4, wherein

the step (e) further comprises the step of:

(e-2) determining a clipping area in said trimming area to designate a part of said image of said picture to be used in said integrated image.

6. The method of claim 5, wherein

the step (f) comprises the step of:

(f-1) transferring said page description program to said integrated image recorder together with second accompanying data including;

said numbers of pixels forming said second pictorial image data in said two directions.

7. The method of claim 6, wherein

said second accompanying data further includes:

said file name of said second pictorial image data;

a number of bits representing said integral image per pixel; and

data designating whether said integrated image is monochrome or color.

8. The method of claim 7, wherein

said second accompanying data further includes:

data designating a position of said trimming area and a shape of said clipping area on said image plane.

9. An integrated image recorder for recording an integrated image including images of a character, a graphic and a picture, comprising:

(a) first interface means for receiving first pictorial image data of a given amount representing an image of a picture obtained from an input device;

(b) means for reducing the amount of said first pictorial image data to obtain second pictorial image data representing said image of said picture in a second resolution lower than said first resolution;

(c) memory means for storing said first and second pictorial image data under a file name;

(d) second interface means for transmitting said second pictorial image data from said memory means to a front end processor coupled to said integrated image recorder and for receiving from said front end processor a page description program representing an integrated image in a page description language,

said front end processor being effective to integrate an image of said picture represented by said second pictorial image data with respective images of a character and a graphic on an image plane corresponding to a page to generate said page description program;

(e) means for converting said integrated image into a bit-mapped image as a function of said image description program and said first pictorial image data to obtain image data of said integrated image;

(f) buffer memory means for storing said image data of said integrated image; and

(g) recording means for recording said integrated image on a recording medium as a function of said image data of said integrated image,

wherein the means (b) comprises;

(b-1) means for skipping pixels of said first pictorial image data at a predetermined rate to obtain said second pictorial image data, wherein

the means (e) comprises;

(e-1) means for converting coordinates of said character, said graphic and said picture on said image plane.

10. The integrated image recorder of claim 9, wherein

the means (e) further comprises:

(e-2) means for determining a trimming area of said picture in accordance with a trimming data received from said front end processor.

11. The integrated image recorder of claim 10, wherein

the means (e) further comprises:

(e-3) means for clipping a part of said picture in said trimming area in accordance with a clipping data received from said front end processor; and

(e-4) means for expanding into said bit-mapped image said part of said picture clipped out by said means (e-3).
