〔Example〕

1 and 2 show an embodiment of the invention. This is a digital copier. In FIG. 1, 201 is an image signal generation unit, which inputs the image on the document into a line sensor, for example, a CCD, by moving the optical system in a direction perpendicular to the line sensor, and reads image information line by line from this COD. This system converts the image data into ADfi in real time, converts it separately, and outputs it as digital data pixel by pixel. Hereinafter, the direction of the line of the line sensor will be referred to as the main scanning direction, and the direction of movement of the optical system will be referred to as the sub-scanning direction. 202 is an initial correction section, and the image signal generation section 2
Correction 1, for example, shading correction, is applied to the image data from 01 onwards.

203 is a character compositing unit (first compositing means) which combines the original image from the initial correction unit 202 and a selector 2 to be described later.
A first composite image is formed from the characters from 07 onwards. Reference numeral 204 denotes an enlarging/reducing unit (variable magnification means) which, for example, writes or reads 1942 main scanning portions into the RAM and changes the magnification by controlling the clock. 2
Reference numeral 05 denotes various processing units that perform various processing on the image from the enlargement/reduction unit 204, such as output correction such as gamma correction. A character generation unit 206 generates information such as characters and symbols to be added on. A selector 207 switches the character data from the character generation section 206 to the character synthesis section 203 and a character synthesis section 208, which will be described later. The character composition section (second composition means) 208 forms a second composite image from the character from the selector 207 and the processed original image from the various processing sections 205. 209 is a printer (output means) that outputs the second composite image data from the character 208 and the enlargement/reduction unit 2;
For example, a laser beam is output based on either the first composite image data and the original image data obtained from 04 through the character composition unit 208, and the first composite image, the second composite image, and the original image are generated. Print out one of the following. The character composition section 203.2
The configuration of 08 is shown in FIG. The character compositing unit 208 is shown as a representative among the character compositing units 203 and 208, and since it is Wi-only, the initial correction unit 202, the enlargement/reduction unit 204, and the digital copying machine shown in FIG.
, the various processing units 205 are deleted. The same parts as in FIG. 1 are given the same reference numerals.

In the figure, 302 is a synthesis circuit that synthesizes a document image and a character by, for example, a logical sum. 304 is an add-on RAM in which selected characters, etc. are expanded. This does not need to have memory for one screen,
Memory only within the add-on area is sufficient. 305 is a main scanning counter, which uses the V C (video clock) signal as a clock to perform B D (beam detect).
) The main scanning position is detected by counting the signals, and the CPU 30
It communicates with B. 306 is a sub-scanning counter;
The BD double signal clock is V S (video
5ynchronization) signals to detect the sub-scanning position and communicate with the CPU 308. The VC signal, which is a reference signal at the leading edge of the BD double signal laser in the main scanning direction, is a clock of an image signal, and the VS signal is a leading edge reference signal in the sub-scanning direction. Reference numeral 307 denotes an operation unit for inputting instructions for selecting an add-on character, output position, and copy start to the CPU 308.

The CPU 308 selects from the RAM 309 and the ROM 310 according to the characters inputted through the operation unit, and selects the data from the add-on RAM 304 which is a bitmap memory.
This will be expanded to.

Further, the CPO 308 controls a clock as a character equal magnification changing means, and controls the character generation unit 206.
It is used to scale or change the scale of the characters output from the . Further, the add-on output position specified by the operator and the output values of the counters 305 and 306 are determined, and a character is sent from the add-on ARAM 304 to the synthesis circuit 302 in accordance with the M manuscript image.

Next, the operation will be explained based on the flowchart shown in FIG.

The operator selects whether or not to add a character using the scanning unit 307 (S-t); if not, select
Just wait. When selecting a character add-on, the character is designated by, for example, an alphabetic key 5-2) and a series of sentences or characters is input.

Then, the RAM 309 and ROM 31 are
A character code is read from 0, and a character corresponding to this code is developed in the add-on RAM 304, which is a bitmap memory.

Next, the output position of the character, that is, the coordinates of the upper left corner, is entered manually using the numeric keypad of the operation unit 307 (S-3). Then, select whether to scale only the character, only the original image, or both the character and the original image (5-4), and select the magnification according to this selection (S-5).
).

When the magnification is selected, the CPO 308 selects the selector 20.
7 is set, and the start timing for reading out characters from the add-on RAM 304 is determined based on the selected magnification (S-S).

(a) When changing the magnification of a composite image, the optical system is moved in a direction perpendicular to the COD, the image information on the document is read line by line by the COD, and the read image data is AD converted and converted in pieces in real time. Each pixel is output as digital data to the initial correction unit 202. The image data manually input to the initial correction unit 202 is corrected, for example, shading corrected, and on the other hand,
A character is read from the character generation section 206 and outputted by the clock control section 210.

The original image corrected by the initial correction unit 202 is directly input to the character synthesis unit 203, while the character output from the character generation unit 206 is input to the character synthesis unit 203 via the selected selector 207 A. be done. The character compositing unit 203 combines the original image and the character to form a composite image, and this composite image is scaled by the enlarging/reducing unit 204 . The composite image is then subjected to various processes, such as output correction such as gamma correction, by the various processing units 205, input to the printer via the character composite unit 208, and synthesized by the printer 209 based on the input composite image data. The image will be printed out.

(b) When scaling only the R84 image In this case, the selector B is selected, so the character from the character generation section 206 is input to the character composition section 208 via the selector 207. Therefore, only the original image is input to the enlargement/reduction section 204 via the character composition section 203, and the enlargement/reduction section 204 changes the size of the original image. Various processing units 205 then perform various processes, such as output correction such as gamma correction, and the corrected original image is input to a character compositing unit 208.
This original image and the character are combined and output to the printer 209.

(C) When scaling only characters: The character is scaled by controlling the read clock of the character generating section 206. If selector A is selected, the character compositing unit 203
The character outputted through
08 to the printer 209. On the other hand, if selector B is selected, the image is output to the printer 209 via the character compositing unit 208.

Although this embodiment shows a configuration in which the processed image is printed by the printer 209, a configuration in which the processed image data is stored in a memory or transmitted to an external device may also be used.
