Abstract

PURPOSE:To prevent crook and folds of an object caused by sliding, by preventing a two-dimension pickup device from sliding directly on the object. CONSTITUTION:The two-dimension pickup device 1 is constituted incorporatedly with a moving amount detecting section 2 and a control circuit 3, and when it is slided left and right on the object such as a book placed on a desk, the movement amount detecting section 2 generates a signal every time a two-dimension input device main body 5 is moved for a prescribed distance on the object relatively. The control circuit 3 outputs a picture signal picked up from the two-dimension pickup device 1 by taking this signal as a trigger signal. Further, a picture storage section 7 controls the sequence by storing a series of picture signals inputted from the two-dimension pickup device 1 tentatively, and a picture signal directed to the correct direction at all times is outputted even if the input device is moved an any direction.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an image input device such as a copying machine.

Conventional copying machines have a photography section and a printing or developing section that are integrated into one unit, and the drawback is that they cannot be easily held.

In order to compensate for these drawbacks of the copying machine, the present invention has been improved so that the photographing part of the copying machine is configured independently, and images are taken by moving a two-dimensional imaging device parallel to the subject. be.

FIG. 1 is a conceptual diagram regarding the basic configuration of the present invention. . The dimensional imaging device (1) is configured integrally with a movement distance detection unit (2) and a control circuit (3), and is configured to slide in the left-right direction over an object such as a book placed on a desk, for example. The movement amount detection section generates a signal each time the two-dimensional input device main body (5) moves a certain distance relative to the subject. Using this signal as a trigger, the control circuit outputs an image signal captured by the two-dimensional imaging device.

FIG. 2 is a conceptual diagram regarding another basic configuration of the present invention.

This basic configuration differs from that shown in FIG. 1 in that it includes a moving direction detector (6) and outputs the moving direction signal of the main body (5) separately from the image signal.

By using this basic configuration, when photographing a subject such as a book, this moving direction signal can be used during playback or recording, regardless of whether the image is taken by moving the two-dimensional camera to the left or right. It has the advantage that an erect image can be reproduced or recorded by determining the reproduction order or recording order.

FIG. 3 is a conceptual diagram regarding another basic configuration of the present invention.

This basic configuration differs from that shown in FIG. 2 in that an image storage section (7) is additionally provided inside the main body (5). This image storage unit has a function of temporarily storing a series of image signals input from the two-dimensional imaging device, and uses the movement direction signal to record the signal in this image storage unit or read the signal. Sometimes, by controlling the order, an image signal always oriented in the correct direction is output no matter which direction the input device is moved.

FIG. 4 is an example of an integrated copying system using the image input device according to the present invention. The self-propelled image input devices θ, a→ are connected to the receiver α, which consists of image storage devices, etc., and the images taken while moving over the subject are sent to the monitors α1, (I→). The image captured in this way is then outputted by the printing machine 10 via the printing control device (9).At this time, if the printing machine is fully used, an auxiliary memory such as a hard disk is used. Temporary data 2 is stored in the device ◇◆ and printed while the printing machine is free.For portable terminals, the image signal line should be directly connected to the print control unit. Figures 5, 6, and 7 are one embodiment of the two-dimensional imaging device according to the present invention.Two-dimensional imaging device? 9 is fixed to the frame (C), and a guide ring (C) having a rotating shaft parallel to this is rotatably fixed to the frame (A). Angle detector (a)
is attached, and this detector generates an electric pulse every time the guide wheel (c) rotates a certain amount. In this device, the two-dimensional imaging device Q11 operates according to the moving distance signal measured by the rotation angle detector (A).
In response to a trigger signal issued from the control circuit (c), the screen is scanned in the horizontal and vertical directions at least once, and the surface brightness distribution of the object (1) is digitized and output to the outside.

In this way, by moving the main body (A) in the same direction over the subject, the main body (C) can repeatedly measure the luminance distribution in a certain size area on the subject at regular intervals. , is output.

FIG. 8 shows another embodiment based on the basic concept shown in FIG. 3. In this example, a three-phase pulse generator (0) which also serves as a movement direction detector is used as a movement amount detector, and three types of pulse generators with a phase difference of 120° are generated depending on the rotation of the guide wheel. Output timing signal summer 01. Output ffl,02. Of these, ΔO is used to control the recording of image signals into the image puffer memory and the reading of image signals from the image puffer memory via the output control circuit. Also, ffl,
02 and yO are connected to a moving direction determination circuit.

That is, when the image input device moves in the direction of A in FIG. 8, the pulse generation order is ff01. ffl, summer 2, and conversely, when the image input device moves in the direction of B in FIG. 8, the pulse generation order is summer O1, summer 2z1. By adopting this method, even if input is performed while moving the image input device in the direction of A, B, or G, the resulting image will not be a mirror image but can be output as an erect image or an inverted image. .

Figures 9 and 7 show another embodiment of the invention.

This example is characterized in that the guide ring is formed of a transparent cylindrical body, and a two-dimensional imaging device O]) is disposed inside the guide ring. By using this structure,
The two-dimensional imaging device no longer slides directly over the subject, and furthermore, the location where the amount of movement is measured can almost match the area to be photographed, thereby preventing the occurrence of distortions, wrinkles, etc. on the subject due to sliding. This has the effect of making the timing of image capture more accurate.
