Abstract

PURPOSE:To process information according to a user's own usual temperature unit and date display by providing a set means which selects and sets a format for setting date based on a set temperature unit. CONSTITUTION:As for the selection of the temperature unit, whether a function key is pressed or not is checked. When it is pressed, the value of a flag DSP-I provided to a RAM 27 is changed. Then, a character shown by the flag DSP-I is made to flicker and what is the temperature unit which is selected at this time and which can be changed to be set is informed to a user. Therefore, when the temperature unit is changed, the function key is pressed until the temperature unit is made to flicker. When it is pressed, the present value of the flag DSP-I is discriminated. When the temperature unit flickers, the value becomes the DSP-I = 1. Then, a flag UNIT-C provided to the RAM 27 in order to show the temperature unit is changed. In the case of deg.C, the flag UNIT- C is made to correspond to UNIT-C = 0, and it is made to correspond to UNIT-C = 1 in the case of deg.F. In order to change the display, a character signal is sent to a character generation circuit 25. Based on the changed flag UNIT-C, the format for setting date is changed.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to an infrared imaging device, and more particularly to an infrared imaging device that allows temperature display units and date setting formats to be selected and set according to the country in which the device is used.

[Prior art and problems of the invention]

When taking infrared photographs, the temperature of the subject is calculated, but as is well known, the commonly used temperature units around the world are Celsius and Fahrenheit, and the distinction between these customs varies depending on the region. be. That is, Fahrenheit is commonly used in the United States and Canada, while Celsius is commonly used in Japan and Europe. Furthermore, the order in which customary displays of date and time are displayed differs depending on the region. For example, in the United States and Canada, "hour: division/day/year" and in Europe, "
"Day/Month/Year Hour: Minute" is commonly used. Therefore, when a product is exported to various countries around the world and used in each country, if there is only one type of display format as described above, temperature information will be processed using a display method that is not customary in that country. The user has to set the date and time, which is extremely troublesome for the user. The present invention has been made in view of the problems in the prior art as described above.
This was devised to effectively solve this problem. Therefore, an object of the present invention is to provide an infrared imaging device that can be used in any country around the world and still display temperature and date in the display style customary in that country.

[Means to solve the problem]

The infrared imaging device of the present invention includes setting means for setting a temperature unit used for humidity evacuation of a subject and selecting and setting a date setting former based on the set temperature unit.

[Action and effect of the invention]

In the infrared imaging device according to the present invention, the display mode of the temperature unit is specified for the setting means which has two types of display modes, the so-called American type and the European type, in which a temperature unit and a date setting format are combined. When a signal is input, a temperature unit display mode is set, and a date setting format is also set based on the set display mode. Settings can be switched by switching input signals to the setting means. Therefore, the user can process information according to his or her customary temperature unit and date display, and is freed from operational hassles.

【Example】

A preferred embodiment of the present invention will be described below with reference to FIGS. 1 to 1O. Infrared rays are always emitted from objects whose temperature is higher than absolute zero, and the amount of infrared rays emitted has a correlation with the temperature of the object. This device takes advantage of this to capture the infrared rays emitted from each part of the object, performs signal processing, and
Changes in the amount of infrared rays are displayed as differences in brightness. FIG. 1 is a block diagram showing each configuration of the apparatus of this embodiment, and FIG. 2 is a schematic diagram for explaining that the apparatus of this embodiment performs two-dimensional scanning. Infrared rays from an object are reflected by a polygon mirror 2, and then condensed onto a multi-element infrared detector 5 via an infrared condenser lens 3 and a filter 4 selected according to the observation temperature range. The infrared detector 5 outputs a signal according to the amount of incident infrared light. By the way, the polygon mirror is rotated in one direction at a constant speed by a motor 41. Therefore, one band is scanned in the lateral direction by rotation of one surface of the polygon mirror 2 (FIG. 2). One band includes a large number of lines corresponding to the number of elements of the multi-element detector 5. On the other hand, since the adjacent surfaces of the polygon mirror 2 are inclined at a fixed angle to each other, the rotation of the polygon mirror 2 causes the first surface of the polygon mirror 2 to be in the first band B, and the second surface to be in the second band B. The planes and bands correspond to each other in this way, and are scanned in the vertical direction. In this way, scanning is performed in the horizontal and vertical directions, and two-dimensional infrared information of the object is obtained by successively receiving light with the multi-element infrared detector 5. The output signal of the detector 5 thus obtained is transmitted to the preamplifier 6.
After being amplified by and signal-processed by low-pass filter 7,
It is input to the offset injection circuit 8. The offset injection circuit 8 includes a D/A (f' fugital analog) converter 11 for the output signal from the low-pass filter 7, as described later.
The signal output from is injected. This allows the reference level (offset level) of the output signal from the low-pass filter 7 to be changed freely. The output signal of the offset injection circuit 8 is input to the multiplexer 12, where signals corresponding to the number of elements of the multi-element detector 5 are multiplexed one after another, and after being amplified by the amplifier 13, the output signal is input to the multiplexer 12.
The signal is input to a D (analog/digital) converter 14. A
The signal converted into a digital quantity by the /D converter 14 is guided to an image memory 15. On the other hand, the polygon mirror is rotating, and the rotation is detected by the photosensor 16. The output of the photosensor 16 is inputted to an input address counter 18 via a timing generation circuit 17, and is regularly counted as the polygon mirror 2 rotates. This count value is supplied as the address of the image memory 15. Then, the digital signals guided to the image memory 15 described above are sequentially and regularly stored in accordance with this input address. When the polygon mirror 2 rotates once in this manner, image data for one screen is stored in the image memory 15. The data in the stored image memory is
This will be read out and displayed, and this will be explained below. A signal synchronized with the television signal output from the television synchronization signal generator 19 is input to the output address counter 20. The output address counter 20 successively generates addresses for specifying data in the image memory 15 based on the television synchronization signal. Output address counter 2
The output of 0 is input to the address of the image memory 15, and the data at the specified address is read out one after another.
OM (gamma-programmable read-only memory) 21
is input. The γ-PROM 21 performs γ correction. Generally speaking, the temperature and energy of an object, the voltage and brightness of a CRT screen, and the amount of incident light and the amount of light that enters the human eye are not linear, so this γ-FROM 21 The temperature of the object and the amount of human sensing are corrected so that they are almost linear. The output of the γ-FROM 21 that has been γ-corrected in this manner is input to the D/A converter 22 and converted into an analog quantity. The synthesis circuit 23 synthesizes the analog quantity obtained by the D/A converter 22 and various character information generated by the character generation circuit 25. The output of the synthesis circuit 23 is sent to the display device 24.
is entered and displayed. Note that the output of the synthesis circuit 23 can be supplied externally as a decoded video signal, so for example, it is possible to supply this decoded video signal to an external monitor television for display.
Recording is also possible if supplied to a video tape recorder. Note that the terminal 42 is a terminal that outputs a start/stop signal for the VTR. As described above, while an infrared image is generated and displayed,
A CPU (central processing unit) 9 controls the device, calculates the temperature of an object, and controls character display. The focus adjustment involved in adjusting the infrared image is explained below.
The offset level and gain adjustment will be explained. These operations are performed by the CPU 9 detecting that the key switch 29 has been pressed. When the focus key is pressed, the CPU 9 detects this and
A motor drive signal is output to the focus lens drive circuit 30. The motor 36 is a motor for driving the infrared condensing lens 3, and when a motor drive signal is applied to the motor 36, the infrared condensing lens 3 moves up and down.
Focusing is performed. Offset adjustment includes manual offset adjustment and automatic offset adjustment, and the CPU 9 switches between them by detecting that a specific key switch is pressed. In the case of auto offset adjustment, the CPU 9 sends an auto signal to the auto/manual switching circuit 39, and the comparison circuit 38
Enable the signal output from. The comparison circuit 38 is configured to output a down signal when the signal level of the amplifier 13 is higher than a certain value Va, and output an up signal when it is lower than a certain value vb. Va and vb are determined by circuit constants. On the other hand, since the clock pulse is output from the CPU 9 to the counter 10, the D/A converter 1
The input value of 1 changes, and the offset injection amount changes. In this manner, in the case of offset adjustment, feedback is applied so that the output level of the amplifier 13 is between Va and vb, and the offset injection amount is automatically determined. In the case of manual offset adjustment, CPU9
Send a manual signal to the manual switching circuit 39,
The signal input from the comparison circuit 38 is invalidated, and the CPU 9
The up/down signal to be outputted from the counter 10 and sent to the counter 10 is enabled. Since the CPU 9 outputs clock pulses to the counter 10 while outputting up/down signals, the D/A
The input value of the transducer 11 changes and the offset injection amount changes. Gain adjustment includes circuit gain switching and filter switching (hereinafter both will be collectively referred to as window adjustment). When switching the circuit gain, CPU9
Change the gain of 3. When switching filters, CP
U9 outputs a range motor drive signal to the range filter drive circuit 31, drives the motor 37, and switches the filter 4. Next, a description will be given of how the CPU 9 calculates the temperature from the signal obtained by the detector 5. The output signal of the preamplifier 6 is sent to the sample hold circuit 32.
and is sampled by a sampling signal from the CPU 9. The sampled and held signal is input to multiplexer 34. On the other hand, from the detector 5, a signal related to sensitivity corresponding to the temperature of the detector 5 itself,
The output signal of the temperature sensing element 33 built into the device is input to the multiplexer 34. These three signals are multiplexed one after another and input to the A/D converter 35, converted into digital quantities, and taken into the CPU 5. The CPU 9 calculates the temperature of the object based on these three digital quantities. To calculate the temperature above, use the key switch 2.
Executes when a specific cow located at 9 is pressed. In addition, the CPU 9 can know the current time by accessing the clock IC (integrated circuit) 28, and
By sending a character signal to the character generation circuit 25, it is possible to display the above-mentioned character information such as the calculated temperature value of the object and the time on the display device 24. Note that the ROM (read-only memory) 26 includes the CPU 9
The RAM (arbitrary access memory) 27 is connected to the CPU 9.
is used to store data. E'FROM (Electrically Erasable Programmable Read Only Memory) 40 stores calibration information used by the CPU 9 to calculate the temperature. The key switch 29 is provided with various keys shown in FIG. 4. As described above, the key switch 29 includes a focus key for adjusting the infrared image, keys for adjusting the offset and window, and the like. When a switch is pressed, the intersecting patterns at that switch become conductive. When the CPU 9 detects which switch has been pressed, it first sets the output terminal O3 to a high level. Then, it scans input terminals 14 and detects terminals that are at high level. Now, if switch F is pressed, output terminal O3 and input terminal I3 are electrically connected, and input terminal I
3 is a high level. The CPU 9 detects which switch has been pressed based on the combination of these high level terminals. If none of the switches N, F, W/B, F/M are pressed, the input terminal! , to I4 are all at low level. In this case, the CPU 9 next sets the output terminal Ol to high level and similarly scans I4 from the input terminal. The output terminal Os is also scanned in the same manner. below,

It is checked whether the W key has been pressed for a certain period of time (for example, 2 seconds) or not, and if it has been pressed, the process advances to #28. At #28, if the current auto-offset state is present, a signal is output to the auto/manual switching circuit 39 so that the offset can be adjusted manually. If it is not in the auto-offset state, a signal is output to the auto/manual switching circuit 39 so as to enter the auto-offset state. Then, in #29, the flag 01 FLAG provided in the RAM 27 is rewritten to indicate three states: an auto-offset state, a state in which the offset can be adjusted manually, and a state in which the window can be adjusted by manual offset. In this case, depending on whether the window can be adjusted with auto offset or manual offset,
Three states are expressed by changing the value of FLAG like the above-mentioned FRZ, and each state is used at the time of determination. Next, in #29-1, a character signal is output to the character generation circuit 25 in order to change the character based on this 01 FLAG. If the O/W key has not been pressed for a certain period of time or more, it is checked in #27-1 based on 01 FLAG whether or not the auto-offset state is currently in effect. If it is in the auto-offset state, no processing is performed and the process returns to #5. If it is not in the auto-offset state, in #29, rewrite 0jPLAG to alternately switch between manual offset adjustment and manual offset window adjustment according to switch operation, and change the character in #29-1. do.

At #30, it is checked based on Of FLAG whether offset or window is currently selected. If the offset has been selected, the process advances to #31 and the offset is changed by outputting a clock to the counter 10. And in #32,
A character signal is output to the character generation circuit 25 to notify that the offset has been changed. Next, in #33, it is checked whether the ten key or the one key has been pressed continuously, and if it has been pressed continuously, the process returns to #31 and the offset is continued to be changed. When the 10th key or 1st key is released, the process advances to #34 and stops changing the offset.
Clear the characters indicating that the offset has been changed and return to #5. If the window is selected, the process advances to #35 and the window is changed. The gain or range filter of the amplifier 13 is switched, and a character signal is outputted to the character generation circuit 25 in order to change the character indicating the window at #36. Next, in #37, a check is made to see if the 10 key or 1 key has been pressed continuously, and if it has been pressed continuously, the process returns to #35 to continue changing the window. When the ten key or one key is released, the process advances to #38, stops changing the window, and returns to #5. If the function key was pressed, #44
Proceed to. Here, a flag DSP is provided in the RAM 27 to indicate three states: whether the immiscibility can be changed using the up or down key, whether the saved temperature value can be displayed, and whether the temperature measurement mode can be changed.
Change the value of L. Then, the process returns to #5, but in #6, a specific character is blinked based on the value of DSP L to notify what processing is currently being performed with the UP key or DOWN key. If the up key or down key has been pressed, it is checked in #39 whether the value of DSPL is O. If DSP L is O, proceed to #40;
The imicibility value is changed, and in #40-1, the value is sent to the character generation circuit 25 to change the character. Move and return to #5. If DSjL is not O, DSP in #41
It is checked whether L=1 or not, and if DSjL=1, the temperature value etc. saved in #42 is displayed on the screen. Then check in #42-1 whether the up key or down key has been pressed again, and if it has not been pressed, go to #42-1.
Return to 2-1, pool, and if pressed, return to #5. If DSP L=2, proceed to #43 and change the temperature measurement mode. Here, the user selects whether to calculate the temperature value as an instantaneous value, as an average value over several seconds (for example, 0.5 seconds or 2 seconds), or as a peak value. Then, in #48, a character is sent to the character generation circuit 25 to display this temperature measurement mode. Move and return to #5. Next, interrupt processing will be explained with reference to FIG. 3(e). The polygon mirror rotates at a constant speed, but enters interrupt processing every time it rotates. First, it is checked whether the flag FRZ, which is changed by pressing the F/M key at #I-1, is 2 or not. F
If RZ=2, no further processing is performed and the interrupt processing ends. When FRZ=2, the temperature at the center of the screen is calculated by the following process. first,#
In order to sample the central part of the signal output from the preamplifier 6 at I-2, a sample hold circuit 3 is used.
