DE1499373C - Device for displaying a composite image from fixed and variable image data - Google Patents

Description

The present invention relates to an apparatus for displaying a composite image from fixed and variable image data, the data-bearing elements being encoded and in one Storage device are arranged, which, if necessary, a control device for locating the by their coding has identified elements, with a first television recording arrangement for detection at least part of the selected element carrying the fixed data, the first video signal representing the information on the portion of the fixed data to be detected generated, with a second television pickup arrangement for detecting one of the variable ones Image data carrying element, which is the information of the variable data of the considered element generated second video signal representing, with a video signal mixer for mixing the first and second video signals and having a monitor for displaying the mixed video signal.

From US Pat. No. 2,938,949 a television arrangement is known with which a marking can be superimposed on the television screen, however, no fixed and changing data used structural elements from which a composite image is created.

Storage devices for cards carrying data are known in which the cards are encoded and from a control device can be searched out. Such encodings can e.g. B. according to the USA.-Patent 3,036,291 derived from the image data and applied to the frame of the bearing the data Element are applied.

Furthermore, the prior art includes various devices for mixing the Television receiving arrangements supplied video signals, such. B. from "Bild und Ton", No. 7/1956, Pp. 174 to 179, or from »E.B.U. Review, Part A - Technical ", No. 56, August 1959. pp. 6-10.

A television recording arrangement is also known which has an adjustable magnification control for viewing all or part of the image data.

It is an object of the present invention to provide an apparatus, in part by combination already known devices that produce a composite image of fixed and variable image data delivers, with a great deal of freedom with regard to the choice of the section to be displayed, the magnification, the updating and commenting of the variable data etc. is given.

The object of the invention is achieved with a device which is characterized in that the first television receptacle assembly has multiple magnification factors and an adjustable magnification control has, so that optionally all or only a part of the fixed image data one selected element can be detected, each element carrying the fixed data several elements carrying the variable data are assigned, each of which is associated with the different parts of the associated, fixed data-bearing element that can be detected, and those in accordance herewith and in accordance with what is required for such part Surgery factor are coded, and by itself known means for finding a desired variable data bearing element which (a) the selected, fixed data-bearing element, (b) the considered part of the fixed Data and (c) corresponds to the magnification factor to which the monitor is set.

The fixed data can contain information such as a map, a graph, a Drawing, descriptive and / or tabular information, commonly used as a background or

ίο called practically permanent information can, and every fixed data container or every "chip" can be encoded so that, er can optionally be output from an information storage device, box or device.

The selection of such fixed data can be done manually, semi-automatically or automatically, e.g. B. can be made by an "address" system for the optional output of stored information.
The fixed data can be contained on a microfilm frame or strip of frames, or on a strip of film, each frame commonly referred to as a "slice". Such a microfilm can be made in the form of a carriage which lies in or is carried by a frame or holder. Ver. Mutable data can be contained on a clear or translucent disk or disk which can be substantially larger than the microfilm so that the information on such a container can be updated and / or annotated and / or otherwise changed. The composite or superimposed image can be obtained by optionally capturing and displaying all or a selected part of the fixed data or information with the magnification factor of the fixed data, which is related to the size of the part or section of the fixed data to be captured and displayed . The selection of the associated variable data may be related to the particular portion or portion of the fixed data thus captured and displayed, and may further be related to the degree of magnification used in the process of displaying the fixed data. Thus, in short, the selection of the fixed data can be made a function of a coded address system or a simple index system, and the selection of the variable data is preferably a function of the selected fixed data and the detected part or section as well as the magnification factor.

Although the representation of fixed data can be assigned a variable enlargement factor can that with the section of the totality of the fixed data which is actually recorded and displayed is, is related, the representation of variable data is preferably done with a fixed one Magnification factor which corresponds to the size of the disk for variable data (which are all the same size) and is related to the size of the display device of the screen on which the composite Image is represented.

From the foregoing it can be seen that a presentation system is proposed, in which the composite representation of selected fixed elutes and selected changeable Data, an update or an addition of notes to the variable data and the

For example, disk can have a code designation that reduces the field of view to two thirds, for variable data, the basic code designation of the total field, half of the total field, a voltage of the assigned fixed data disk plus a quarter of the total field, one sixteenth of the code representation of the enlargement factor , catfish field, etc. according to the size of the disk and 35 rather the percentage of the total field of the fixed data of the selectability of the device, disk can be made, which is detected, and which can also contain a code to detect and enlarge the rather also a code that defines the field of view is used. Where the field of view represents grid coordinates which are reduced to the specific section of the fixed data slice recorded in this way, obviously four different sections 30 can be seen when a plurality of different slices for viewing the total field in the reduced for variable data of a single fixed data view fields can be used that are assigned to each other over the pane.

Using principles similar to the circuit in FIG. 6 for hand start self-stop magnification control the position control of the device can also be done in a manual start-self-stop system are executed. The position control may need to be a little more complicated must be built. The horizontal and vertical adjustment of the device can be done with a Manual start-self-stop circuit can be achieved by essentially using a programmed printed circuit Circuit or other programming device is created, which on the address, the code or refer to the index of the selected variable data disk, since this address, this code or this index contains the specific part or section of the fixed data slice that is used by the Device is to be recorded.

Although the present invention is made with reference to fixed data in the form of a disk such as a microfilm or a slide, and the memory as a device for Saving such fixed data disks has been described, the fixed data can obviously also be saved in would be in the form of a calculator with a memory function and the memory device would then be in combined with the computer. Instead of the physical fixed data component, a high-speed printer or a typewriter can be used to write the information retrieved from the storage device prints to visible physical fixed data for inclusion by the device with changeable to deliver optical magnification, and the text-form or tabular or other Information from the storage device via the fast printer can be changed and / or with comments be provided by the variable data component.

When using a high-speed printer in conjunction with a storage calculator or other storage becomes, the ability of the device to be arranged in the vertical direction is great Usability, as it may be useful to restore some of the information previously presented or omit some of the information provided by the high-speed printer.

Data can also be stored on the container in different colors, and that Viewing device, regardless of whether it is a device with variable optical magnification or a TV camera is, can optionally be made sensitive to a color, so that.es a certain color "sees", and made insensitive to all other colors, so that it is the information does not see in other colors. This can be achieved through a color filter system on the recording device will. Where two or more operating positions are used in a single device, You can put different colored annotation devices (such as colored pencils) in the appropriate positions on the disk for variable data.

Another technique can also be used in a system similar to that described herein Principles are used and it consists in the fact that information on a data holder in different Character sizes are stored, d. H. general information in large characters and more precise Information in increasingly smaller characters, depending on the level of detail. the Characters of any particular category of accuracy can be made of such a size that that they are legible at a certain magnification and other characters at the same magnification are not readable. Using this technique, information can be subject to change Degree of accuracy housed on the same data disk and optionally according to the desired Details are considered as it is controlled by the magnification of said device. So z. B. general information about a particular topic or device from a particular one Data containers are presented on which the entire and complete information is stored are, without disclosing more detailed information, that are on the same data disk are stored.
