Abstract

PURPOSE:To make it possible to store the same record as a display picture and to record or output specific processing contents. CONSTITUTION:A processing part 10 receives image displaying input data from the external, edits the input data and classifies the edited data into plural segments each of which is to be treated as a collected processing unit. A plotting part 11 converts each segment into a video signal and supplies the video signal to a display part 15. An operation input part 12 specifies a specific segment and stores the specified segment in a storage part 13. The stored contents are read out by a controller 14 and outputted from an external output part 16 or stored.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device, and more particularly to a display device that performs graphic processing by classifying and outputting data to be displayed on a display into segments that are a collection of display elements that can be treated as one processing unit. Regarding.

2. Description of the Related Art Conventionally, this type of display device inputs display data from the outside and edits it using a microprocessor or the like, and separates each set of display elements, which can treat the data to be displayed as one processing unit. Drawing data was created by classifying it as segments and updating it as needed, and the drawing unit performed correspondence to the display screen, brightness and color processing, and displayed it on a CRT or the like.

[0003] In the above-mentioned segment information, for example, in the display of an airport control system, a predetermined map of the controlled airspace and an aircraft symbol as a moving target moving on this map are each treated as independent segments. In addition to positional information based on coordinate data that provides positional information of a display image, brightness information of a display screen, and window information of each of a plurality of frame information forming one display screen, all of these are treated as segment information.

[0004] Furthermore, when display data is recorded in a conventional display device, it is done at a stage before the data is input to the display device.

[0005]

[Problems to be Solved by the Invention] In this conventional display device, records are acquired before data is input to the display device, so if a failure occurs in the data line or processing system after recording, However, there was a problem in that a discrepancy occurred between the image actually displayed on the display device and the recorded image.

[0006] Furthermore, since all data input to the display device is recorded, there is a problem in that it is difficult to extract records of only the part or desired target designated by the operator.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to provide a display device that is capable of recording and storing the same data as the display screen, and is also capable of recording or storing only a specified segment.

[0008]

[Means for Solving the Problems] A display device of the present invention receives input data for image display input from the outside, performs editing processing, and is capable of handling each piece of data to be displayed as one processing unit. a processing unit that classifies and outputs each set of elements as segments; a rendering unit that inputs the segments output from the processing unit and converts and outputs them into video signals that can be drawn as images; and output from the processing unit. an operation input section through which an operator inputs specification information specifying a segment to be specified among the segments; a storage section that stores the specific segment specified by the operation input section; and a readout section for reading out the specific segment stored in the storage section. The image forming apparatus includes an external output section that outputs or stores the video signal, a controller section that controls reading of the stored contents of the storage section, and a display device that displays the video signal output from the drawing section.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention.

The embodiment shown in FIG. 1 includes a processing section 10 that edits input data, classifies it into segments, and outputs it, a drawing section 11 that converts the segments into video signals, and an operation input section that specifies a specific segment. 12, a storage unit 13 using RAM that records a specific segment, and a controller 14 that controls memory readout of the storage unit 13.
A display device 15 using a CRT is provided.

Next, the operation of this embodiment will be explained.

Input data 100 input to the display device is input to a processing unit 10 including a microprocessor, and is converted into segment information 101 as a set of segments with brightness information and window information added. and is input to the drawing section 11.

[0014] Drawing unit 11 receives segment information 101
Then, a video signal 106 is generated and data is displayed on the display 15.

On the other hand, based on the display screen of the display 15,
A specific segment is designated by the operation input section 12 using an input method using a trackball, key switch, etc., and segment designation information 102 such as the coordinate position of a display image is input to the processing section 10 .

The processing unit 10 that has received the segment designation information 102 determines the designated segment, and thereafter outputs the segment information 101 including the segment to the drawing unit 11, and also outputs the segment information 101 that is the same as the designated segment information 101. The data is written into the storage unit 13 as storage target segment information 103.

The information written in the storage section 13 is controlled by a memory control signal 105 from the controller 14, and memory read data 104 is outputted to an external output section 105.

The external output section 105 is composed of an X-Y plotter, a printer, a personal computer, etc., although it differs depending on the purpose, and records the memory read data 104.

Since the storage target segment information 103 includes the above-mentioned position information, brightness information, window information, etc., the display device 1 is processed by the external output unit 16.
It is possible to display an output similar to the image of the segment displayed in 5, or to plot the movement of the segment.

[0020]

Effects of the Invention As explained above, the present invention can specify and save the same segments as those used for screen display after processing the data input to the display device. It has the effect of being able to be preserved.

Furthermore, by specifying the segment displayed on the screen, it is possible to save or output only the record of the specified processing content.
