Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention is applicable to microfilms and other recording materials.
The present invention relates to an image processing device that creates additional information while observing an image.

[Prior art]

Images recorded on microfilm are stable and can be used as permanent double-image memory. When viewing and observing the information on microfilm 1, a request often arises to write notes on information related to it, or it is extremely difficult to modify the information because it is a microfilm.

If this were to be done, a part of the image would be deleted by scanning a minute spot with high energy, such as a fine needle tip or a laser beam. However, all of these methods damage the microfilm. It has a major drawback in that it is impossible to make partial changes without damaging it, and therefore information that should be shared and stored permanently can be personally corrected.

An alternative method is to create a hard copy of the microfilm image and write notes on it, which are then filed separately as derived information. This method is inconvenient and inconsistent in hard copying, memo writing, filing, etc.

[Purpose of the invention]

The present invention has been made in view of the prior art, and it is an object of the present invention to provide an image processing device that can automatically process memo information regarding the screen without observing an image on a recording medium such as a microfilm. do.

[Structure of the invention]

The configuration of the present invention that achieves the above object includes means for projecting an image on a recording body onto a screen, and means for photoelectrically converting and reading the written image while observing the projected image on the screen. This is an image processing device characterized by comprising:

〔Example〕

FIG. 1 is a schematic diagram of an embodiment of an image processing apparatus to which the present invention is applied. In the figure, F is a microfilm, 1 is a light source, 2 is a projection lens, 3 is an optical path cutting mirror, 4 is a mirror,
5 is a screen, 6 is a movable transparent film, and 7 is a movable transparent film drive source. Further, 8 is a photoelectric conversion sensor, 9 is a signal network l'' circuit, 10 is an analog-to-digital conversion circuit,
11 is a memory circuit, 15 is a control circuit, 16 is a circuit for generating a search address signal, 17 is a search device, and 18 is a read command signal generation circuit.

FIG. 2 is a detailed perspective view of the main parts of the apparatus shown in FIG. 1.

The light emitted from the light source 1 passes through a condenser lens 20, a mirror 21, and a condenser lens 22, and illuminates the image on the film F[-. When the switching mirror 3 is at the position indicated by the solid line, the image B of the microfilm is enlarged and projected onto the screen 5 through the solid line indicator path by the lenses 2, mirrors 23, 3, and mirrors 25, 26. A movable transparent film 6 is placed on the front surface of the screen 1) so as to be in substantially electrical contact with it. How many images are written on this transparent film 6 by the pen 28? The transparent film 6 is held and conveyed by a capstan roller 29a and a pinch roller 29b connected to a motor (not shown), and is movable in the direction of arrow X. transparent film 1
The image written in 0-1- is illuminated by a rod-shaped light source 30, and is converted into an image electrical signal and read by a line scanning type reading sensor 8.

In addition! , lJ @ When the mirror 3 is at the position indicated by the chain line, the image on the microfilm F passes through the button line optical path a by the projection lens 2 and is focused on the photoreceptor 13 (see Figure 1), resulting in a printed state. There is.

[Effect]

With such an image processing device, microfilm F-''-
If you want to leave a memo regarding the second image, set the mirror 3 to solid line tone, operate the keyboard (not shown),
Select the desired microfilm image. Then circuit 1
A search address signal enters the control circuit 15 from 6, and the control circuit 15 issues an operation command to the search device 17. When a desired microfilm image is retrieved by the retrieval device 17, an image B is projected onto the screen 5. The projected image B
While observing through the transparent film 6, the image A is written on the transparent film 6 with the pen 28.

A command to read this image A is given by operating the keyboard.

Then, a read command signal is input from the circuit 18 to the control circuit 15. A drive command is issued from the control circuit 15 to the drive source 13.

The motor is rotated by the drive source 13, and the roller 9J 29
The transparent film 6 moves in the direction of arrow X at a and 29b.

The sensor 8 then operates and reads the images A one after another. At this time, the driving speed of the transparent film 6 and the scanning speed of the reading sensor 8 are synchronized by the control circuit 15. The signal of image A is amplified by +lJ in circuit 9 and digitally converted in A/D circuit 10. On the other hand, the control circuit 15 sends a signal to the memory circuit 11 specifying the address corresponding to the searched microfilt image, and the digital copy number of the image A is stored at that address.

The additional information stored in the image A can be recalled as needed, such as when retrieving the same microfilm, and can be displayed on a device such as a cathode ray tube (CRT) display or liquid crystal display, or printed in hard copy by digital copying. get or
Sending is optional.

[Modified example]

FIG. 3 shows an example in which the screen and the transparent film for writing are used together. The image A is written on the screen 33 with the pen 28 while observing the projected image B (shown by the chain line). Once this is completed, the screen 33 can be moved and the sensor 8 can read only the written images A one after another.

FIG. 4 shows another embodiment of the written image reading sensor. The written image on the transparent film 6) is illuminated by the light from the rod-shaped light source 30 that passes through the Fresnel lens 35, and is detected by the charge couple device (C:CD) line sensor 37 by the reduction optical system 36.
is imaged.

〔effect〕

As described above, according to the image processing apparatus of the present invention, while observing a microfilm image, arbitrary additions can be made to the image without any damage to the image, and the added image information can be converted into independent information. It is a convenient item that can be treated as
