Abstract

PURPOSE:To enable a temperature measuring instrument to perform precise temperature measurement display respective parts having different focuses each other in the same vidual field on the same screen at just focus. CONSTITUTION:Parts A-C in the same vidual field are successively focused and data from respective parts A-C are stored in memories A'-C'. Subsequently, data a1, B stored in memories A', B' are accessed and the accessed data are replaced by data already stored in an address of a specific memory C' in the same memory as the address in which said accessed data exist and the replaced data are stored. Consequently, data of the part C, an optional position in the part A and the part B in the same vidual field are stored in the memory C'. The data in the memory C' are accessed and displayed, so that plural parts having different focuses in the same vidual field can be displayed on the same screen at just focus.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for displaying all parts with different focuses in the same field of view on the same screen with just focus.

Generally, when an optical imaging device focuses on a part, parts that are at the same distance as the part are clearly photographed, but parts that are not at the same distance are not clearly photographed. For example, a temperature measurement device that optically scans a subject using an optical scanning mirror, detects infrared rays from the subject, and displays a temperature distribution image of the subject on a screen focuses on a part of the subject. If you align the two areas, all areas other than those at the same distance from the area will be out of focus, so the temperature distribution image for such areas will show the average temperature of the out-of-focus area, making it impossible to measure the temperature accurately. .

The present invention aims to solve such problems.

The present invention optically sequentially focuses on a plurality of parts in the same field of view, stores the data detected from the parts in dedicated memories, and then stores the data in several of the memories other than the specific memory. specifying a certain memory, calling up data stored at an arbitrary address among the data stored in the specified memory, storing it in the same address as the address where the data was located in the specified memory, and This invention provides a new display method for displaying data stored in a specific memory.

The display method of the present invention will be explained below with reference to FIG.

First, focus is placed on part A in the same field of view shown in Fig. 1(a), and the data obtained from this part is stored in memory A'.
to be memorized. Next, focus is set on part B in the same field of view, and data from this part is stored in memory B'.

Next, in the same way as Ir, focus is set on part C in the same field of view, and data from this part is stored in memory C-. After that, focus on other parts in the same field of view in the same way,
The data of the part is stored in the memory of Haku. Here, for convenience, parts A, B, and C in the same visual field are sequentially focused, and data from each part is stored in each memory.

Next, all of the data stored in an arbitrary memory in the memory or data at an arbitrary location in the data is called, and the recalled data is stored in the memory at the same address as the address where the data exists. The data is stored at a specific memory address replacing the data already stored. That is, for example, an arbitrary location in the data stored in the memory C--, for example, al (see FIG. 1(b)) is called up, and this data is stored in the memory C-- which is the same address as the location where the location a1 exists. (see FIG. 1(d)). In this case, multiple locations may be called instead of just one location. Next, all of the data stored in the memory B' (see FIG. 1(C)) is called up, and any part of the data, for example B, is set to the same address in the memory C' as the address where this data exists. (see FIG. 1(d')). In this way, as shown in FIG. 1(d), the memory C-
The data of part C, an arbitrary part of part A, and part B of the same visual field are stored, and all of these data are the data of the thin focus. If these data are retrieved from the memory and displayed, a plurality of portions with different focuses in the same field of view can all be displayed on the same both sides with just focus.

FIG. 2 is a block diagram of a temperature measuring device shown as an example of application of the principles of the present invention. In the figure, reference numeral 1 denotes an optical system consisting of a 1ft Y-direction scan, a Y-direction scanning mirror, and an infrared detector.The scanning mirror optically scans the subject 2, and the infrared rays from the subject resulting from the scanning are transmitted to the infrared detector. I am trying to detect it. Reference numeral 3 denotes a mirror driver that drives each scanning mirror of the optical system to focus a predetermined portion of the object, and operates in accordance with an address signal from an address designation circuit 4 that specifies the address of the portion to be focused. Note that 5 is a DA converter.

The output of the infrared detector of the optical system is supplied to a data acquisition circuit 8 via an amplifier 6 and an AD converter 7. The data acquisition circuit selects one of the memories 10a, 10b, and 10c according to the signal from the memory selector 9, and according to the address signal from the addressing circuit 4, transfers the temperature data from the infrared detector to the selected memory. Store at the specified address. A selector 11 selects only the data in the memory selected by the memory selector 9 and supplies it to the color signal conversion circuit 12. The color signal conversion circuit 12 is a color signal conversion circuit that converts infrared rays from an object, that is, a hot water level signal, into a 1ζ color signal according to its intensity, and converts the temperature signal from the memory selected by the selector 11 into a color signal. Convert to A color cathode ray tube 13 displays the temperature signal of the selected memory in color according to the output of the color signal conversion circuit. Reference numeral 14 denotes a key operation system for specifying the position of a cursor for enclosing an arbitrary part of the image displayed on the cathode ray tube in a frame consisting of the cursor. 15 is a frame designation circuit that emits signals in the X and Y directions corresponding to the cursor position designated by the operating system;
The Y-direction signal and the Y-direction signal are respectively sent to the color signal conversion circuit 12 and the frame data transfer port! The signal is sent to B16 and converted into a specific color signal by the color signal conversion circuit, so that a frame is displayed in a specific color at a designated position on the screen of the cathode ray tube 13.

Further, the frame data transfer circuit 16 transfers the selected memory (
For example, among the data in the memory 10a or 10b), the data at the location designated by the frame designation circuit is transferred to a location corresponding to the location of the designated location in another memory (for example, the memory 10C).

In such a device, a signal for selecting the memory 10a is sent from the memory selector 9 to the selector 11 and the data acquisition circuit 8, and the address data of the part A in the field of view of the subject 2 is transmitted so that the part A in the field of view of the subject 2 is focused. Address designation circuit 4 to mirror driver 3 and data acquisition circuit 8
When the focus data of the Δ portion in the field of view of the subject 2 is captured from the optical system 1 to the data capture circuit,
It is stored in the memory 10a. Subsequently, signals for selecting memories 10b, 10c are sequentially sent from the memory selector 9 to the selector 11 and the data acquisition circuit 8, and at the same time, signals for selecting the memories 10b, 10c are sent from the addressing circuit 4 to the areas B and C in the field of view of the subject 2. The B part and C part are focused so that
The address data of the portions are sent to the mirror driver 3 and the data acquisition circuit 8, respectively, and the focus data of the B portion and C portion in the field of view of the subject 2 is stored in the memories 10b and 10c, respectively, from the optical system 1 to the data acquisition circuit. do.

At this time, temperature distribution images in the visual field of the object are sequentially displayed on the cathode ray tube 13. Next, the memory 10a is selected by the memory selector 9, and the selected memory 1
A temperature distribution image based on the data of 0a is displayed on the cathode ray tube 13. While observing the image on the cathode ray tube, the user operates the key operation system 14 to designate a frame, for example, a location al in the focused portion A. That is, the key operation system 14 is used to designate a plurality of positions indicating the frame of al. As a result of this operation, the frame designation circuit 15 sends signals specifying multiple positions of the frame in the X and Y directions to the frame data transfer circuit 16 and the color signal conversion circuit 12. A frame will be displayed at the specified location.

At the same time, the frame data transfer circuit 16 transfers the data at the location a1 designated by the frame designation circuit among the data in the selected memory 10a to the location corresponding to the designated location in the memory 10c. do. Next, the memory 10b is similarly selected by the memory selector 9, and a temperature distribution image based on the data of the selected memory 10b is displayed on the cathode ray tube 13.

Then, while observing the image on the cathode ray tube, key operation system 1
4, operate B to specify the frame in focus. That is, the key operation system 14 is used to designate a large number of positions indicating the frame B. As a result of this operation, the frame designation circuit sends signals designating multiple positions in the X and Y directions of the location B to the frame data transfer circuit 16 and the color signal conversion circuit 12, so that the designated areas in the CRT image are sent to the frame data transfer circuit 16 and the color signal conversion circuit 12. A frame will be displayed at the location you touched. At the same time, the in-frame data transfer circuit 16 transfers the selected data in the memory 10b to a location corresponding to the designated location in the memory 10C. When the memory selector 9 sends a signal to select the memory 100 to the selector 11, the cathode ray tube 13
In the same field of view of subject 2, point a of part A, B
A temperature distribution image is displayed in which the portion and the portion C are just in focus.

In the above embodiment, for convenience, A and B are in the same field of view.

The three parts of C are brought into just focus on the same screen, but if you do the same thing as above for other parts in the same field of view, you can bring many parts of the same field of view into just focus on the same screen. I can do it. Furthermore, although the multiple positions indicating the frame are specified using a cursor using a key operation system, this may also be done using a light pen.

According to the present invention, parts with different focuses in the same field of view can be displayed on the same screen with just focus, so that, for example, accurate temperature measurement is possible in a temperature measuring device.
