Abstract

PURPOSE:To image various image information by a printer having a single function by converting the image information in a memory based on the output capacity of an image information output device, storing it in the memory again and thereafter, supplying it to an output device. CONSTITUTION:Image information from an input device 1 is stored in a memory 3 and displayed on a CRT 5. In such a case, the number of display dots of the CRT 5 is smaller than the input image information, therefore, the image information in the memory 3 is given to a converter 6 through a bus 11 and reduced and this reduced information is stored in a display memory 4 and displayed on the CRT 5. In this way, the image information in the memory 3 is brought to a magnifying or reducing conversion processing and outputted based on the output capacity of a printer as an output device 2.

Description

Detailed Description of the Invention (a) Field of industrial application (b) Prior art Currently, image information such as documents, sections, etc. is optically captured and this image information is stored in an optical disk device as a storage device. Required 1: Search and read out the desired image information from the image information stored in the original disk device C2.
CRT display device or printer device 3 as an output device: A document file device that can be used has been put into practical use (for example, Sanyo Technical Review Vol.
16. I am familiar with the "Gendisk Kaibun Seisan File System" of N11L2.1984. ).

With such five document file systems, one image information has a very large amount of information, so when this is to be displayed on the CRT display device C2, the image information is reduced.

(c) Problems to be Solved by the Invention By the way, the size and resolution of image information handled in a single document file device are extremely variable; there are many types of image information; therefore, as a printer device for printing single image information, Multifunctionality is required, making the printer device complex and expensive.

An object of the present invention is to perform size conversion or dot number conversion of one image information.Thus, it is an object of the present invention to make it possible to print various types of image information using a single-function printer device 32.

B) Means for Solving the Problems The image processing apparatus of the present invention has a data bus that connects an image information input device, an image information output device, an image memory, and a conversion device included in the image processing device. , the image information input from the image information input device is stored in the image memory C.
: After storing, the above converting device C via the above data bus:
The converted image information is transferred and stored in the image memory≦2 via the data bus, and then the stored image information is transferred to the image information output device C via the data bus. : It is characterized by being equipped with a control circuit for outputting.

(e) Effect According to the present invention I, image information input from one image information input device is stored in one image memory C; then transferred and converted to the conversion device (: transferred and converted, and this converted image information is again The image is stored in the image memory, and then outputted to the image information output device C.

(F) Embodiment FIG. 1 is a block diagram showing an embodiment of the present invention. (
1) is an image information input device consisting of an image sensor, etc. that optically (-reads and converts image information such as documents and drawings), and converts image information into 8 (dots/

J, (6) is the dot number conversion of image information.

That is, it is a conversion device that performs enlargement or reduction.

The conversion device (6) consists of the enlargement/reduction circuit described in Japanese Patent Application No. 60-20632 previously filed by the present applicant. , the conversion device (6) converts the image information based on the conversion rate (1). Image information output device (2) 1 Image memory (3) and display memory (4) each (: provided interface, (11) is a data interface (L) that connects these interfaces and conversion device (6) is a control circuit that performs various controls such as the operation of each interface (7) to (1G input/output and conversion device (6)).

Furthermore, FIG. 2 shows various registers provided inside the control circuit α, and CD represents the horizontal length PX, vertical length PY, and resolution RES1 of the image information input from the image information input device (1). (2) is the second register that stores the horizontal length OX, vertical length OY and resolution RESZ as the output capabilities of the printer which is the image information output device (2), (C) is the second register that stores the output capacity of the printer which is the image information output device (2) 6) Horizontal conversion rate HPR and vertical conversion rate v which are conversion rates at c
This is the third register that stores PR.

Therefore, such a configuration (: image information input device (1)
The image information input from the interfaces (7) and (9) is stored in the image memory (3) (:,). At this time, the horizontal length PX and the vertical universal length PY of the image information are and the resolution RES1 is the second register 121) l
:, stored.

Next, in order to confirm the image information input from the image information input device (1), the image information stored in the image memory (3) is displayed on the CRT display (5). The number of dots displayed on the CRT display (5) is small compared to the input image information 1.

The image information is reduced by the conversion device & (6) (::. Specifically, C; is one image memory (3) This reduced image information is stored in a display memory (4m) via a data bus (Lυ) and an interface αC, and then displayed on a CRT display (5E).

As described above, the image information stored in the image memory (3) is the output capability of the printer as an image information output device (2)! After being subjected to enlargement or reduction conversion processing in two units, it is output.

Below, 1 image memory (3) (n Regarding the output operation of the stored image information, the third factor C2 is the control circuit tt
This will be explained with reference to an example of the program chart in a.

First, the control circuit @ calculates the first stage conversion rate based on the resolution RES 1 stored in the first register 1211 and the resolution RES 2 stored in the second register C. Resolution aEs1 is resolution RESz
When the ratio is larger than the ratio c, RES2/RES1 is calculated as the conversion ratio in the horizontal direction and the vertical direction, and when the ratio is smaller than the inverse 1:, 1 is calculated as the conversion ratio.

Missing 1: The control circuit α2 stores the horizontal length PX and vertical length PY stored in the sixth register (21)l2, and the horizontal length OX and vertical length OY stored in the second register 1221t2. The second stage conversion rate is calculated based on . Specific C: is when the horizontal length PX and the vertical length PY are larger than the horizontal length OX and the vertical length PY (; when the horizontal length PX and the vertical length PY are larger than each other, the horizontal and vertical conversion rates are O
X/PX and OY/PY are calculated, and when the inverse C is smaller than the inverse C, 1 is calculated as their conversion rate.

Therefore, the control circuit 0 multiplies the conversion rates of the first stage and the second stage calculated as described above.Thus, the final horizontal conversion rate HPR and vertical conversion rate VFR2 are calculated, and these The conversion rate is stored in the W,6 register c23.

For example, the horizontal conversion rate and vertical conversion rate of the first stage are aEs2/RES1, respectively, and the horizontal conversion rate and vertical conversion rate of the second stage are OX/PX and O
For Y/PY, the third register! 23 (: The stored horizontal conversion rate HPR and vertical conversion rate VPR are (RE
