However, there is a problem that the usability decreases as the imaging conditions increase. Taking the example of switching the lighting, when the material is normal paper or sample, the lighting lamp installed diagonally above the table is turned on, and in the case of X-ray film, slides, etc., it is built into the table. The transmitted light lamp is turned on. In addition, the aperture and color balance naturally vary depending on the subject. These are adjusted by operating the switches provided on the data presentation device.However, even if the adjustment is made for the X-ray film, if the power is turned off and the product is restarted, the It is normal to return to the settings. In addition, even if the power was turned off, if another person presented different materials and changed to another imaging condition, the adjustment had to be redone.

The material presenting apparatus of the present invention has been made for the purpose of solving these problems and improving the usability of the material presenting apparatus, and has the following configuration.

[0005]

A material presenting apparatus of the present invention comprises an image pickup means for picking up an object such as a material or a sample placed on a placing table, and an image obtained by picking up the object by the image pickup means. A material presentation device that outputs a signal to a display device to present material, and a presentation condition adjusting unit that adjusts a presentation condition of the material, and a presentation condition adjusting unit that adjusts when a predetermined condition is satisfied. And a presentation condition recovery unit for recovering the presentation condition to the condition stored in the storage unit when a specific condition different from the condition is satisfied. And

[0006]

The material presenting apparatus of the present invention configured as described above satisfies predetermined conditions such as when the power is turned off and when the memory switch operated by the user is operated. At this time, the presenting conditions adjusted by the presenting condition adjusting means at that time are stored in the storage means. On the other hand, immediately after the power is turned on, when a specific condition different from the condition for storing the presentation condition is satisfied, such as when a recovery switch operated by the user is operated,
The presentation condition recovery unit recovers the presentation condition to the condition stored in the storage unit. Therefore, the presentation condition once set can be easily recovered.

Bits 6 and 7 of (H) are zoom mode control outputs, and the CPU 301 can switch the zoom modes A and B of the television camera 20 by writing exclusively to these bits.

Next, referring to FIGS. 14 and 15, the CPU will be described.
Among the processes executed by 301, those involved in the invention will be described. FIG. 14 is a flowchart showing a key memory processing routine executed when the key memory setting button 146 is pressed, and FIG. 15 is a power-on processing executed when the entire material presentation device 10 is powered on. It is a flow chart which shows a routine.

As described above, the key memory setting button 146 is the only alternative switch in the control button group 29, and alternately turns on and off each time it is operated. The key memory processing routine shown in FIG. 14 is a routine that is executed when the key memory setting button 146 is operated in the ON state. When this routine is activated, first, the operation button group 28 and the control button group 29 are processed. A process of reading the setting of each button is performed (step S400). The setting of each button is stored in a predetermined area of the RAM 305 every time each button is operated, and therefore, it is sufficient to read the setting.

Next, the read setting is stored in the EEPROM 3
A writing process is performed in a predetermined area 07 (step S
410). When writing the settings, it is also desirable to write the total value (checksum) of these setting values together in a predetermined address of the EEPROM 307 in order to improve the reliability of the data. After that, by writing the value 1 to the bit 1 of the address 0100 (H) of the I / O port 311, the key memory LED 121 is lighted (step S420). After the above processing, "NEXT"
To exit this routine.

The data stored in the RAM 305 by the processing shown in FIG. 14 is the upper illumination unit 2 in this embodiment.
2 or lower lighting unit selection, AV selector selection,
Microphone volume, iris opening, zoom mode, white balance automatic / manual selection, color / monochrome selection, gain switch switching, color bar output or not, and detail switch on / off. In the present embodiment, a DC motor having no drive amount detection function is used for zooming and focusing of the television camera 20.
Although the settings cannot be stored, if a stepping motor is used or an encoder for driving amount detection is used, the focus and zoom states can also be stored.

When the material presentation device 10 is turned on,
The power-on process routine shown in FIG. 15 is started. When this routine is activated, initialization processing is first performed (step S440). As the initialization process, I
Input / output settings for the / O port 311 and the like, and initialization of internal registers of the CPU 301 are performed.

Next, a process of reading the state of the key memory setting button 146 is performed (step S450). Since the key memory setting button 146 is an alternative switch, its on / off state can be directly read. Subsequently, it is determined whether or not the key memory setting button 146 is in the on state (step S460), and if it is in the on state, a process of reading the setting stored in a predetermined area of the EEPROM 307 is performed (step S470). At this time, if the checksum is stored, by comparing the checksum value with the actual total value of the data, E
It is possible to judge whether or not the data stored in the EPROM 307 has an error.

On the other hand, if the key memory setting button 146 is off, the default value of each setting stored in the RAM 305 is read out (step S475).
This is because, when the key memory setting button 146 is not set, the factory shipment state is set. Step S47
After the processing of 0 or 475, the processing of setting these settings in the video / audio processing circuit 250 and the selection circuit 270 is performed (step S480). As a result, if the key memory setting button 146 is on, the key memory setting button 1
If the setting of each button when the button 46 is operated to be turned on is not the key memory setting button 146 is turned on, the setting at the time of factory shipment is reproduced in the material presentation device 10.

Subsequently, the CPU 301 determines that the I / O port 3
Predetermined data is output to 11 to 313, and the LED corresponding to the setting is turned on (step S490). After that, the process exits to "NEXT" and the present routine ends.

The material presentation device 10 of this embodiment described above
According to this, by pressing the key memory setting button 146 to turn it on, various settings at that time, that is, in the embodiment, selection between illumination by the upper illumination unit 22 and illumination by the lower illumination unit, AV signal Settings, microphone volume settings, etc. can be stored and restored to the settings immediately after the power is turned on. Therefore, when the operation button group 28 and the control button group 29 are operated to make settings suitable for a specific purpose, the state can be returned to this state at any time. The advantage that the work can be started from the optimum setting immediately after the power is turned on is extremely desirable from the viewpoint of improving workability. Further, even when a plurality of people use the material presentation device 10, it is easy to return to the specific settings, and the work efficiency is improved.

When the key memory setting button 146 is operated to store the setting, the key memory LED 121 is turned on to indicate this, so that it can be easily known whether or not the setting is stored. Even when the setting is stored, it is easy to change the setting by operating the operation button group 28 or the control button group 29. After changing the setting, to store the new setting, the key memory setting button 146 may be pressed again to turn it off, and the key memory setting button 146 may be pressed again to turn it on. According to the operation of the key memory setting button 146, the key memory LED 121 changes from the lighting state to the extinguished state to the lighting state again. Therefore, it is easy to know how to store the key setting by this operation. In addition, in this embodiment, the setting of each key is set in the EEPROM 307.
Since it is stored in, the key setting can be reproduced even if the power is not turned on for a long time.

Further, in this embodiment, since an alternative switch is used as the key memory setting button 146, there are the following advantages. Key memory setting button 14
6 is a momentary switch and its operation is EEPRO
It can be stored in M307, but in this case E
If the operation state of the key memory setting button cannot be rewritten due to an abnormality in the EPROM 307, there may occur a problem that the setting before the abnormality always occurs when the power is turned on. By setting the key memory setting button 146 as a mechanical alternative switch,
If an abnormality occurs in the EEPROM 307, the key memory setting button 146 can be turned off to cancel the key memory setting.

The embodiment of the present invention has been described above.
The embodiment of the present invention is not limited in any way. For example, instead of the EEPROM 307, a flash RO is used.
A configuration in which the key setting is stored in the RAM backed up by M or the battery, and a key setting recovery button is provided in addition to the key memory setting button 146, and when the key setting recovery button is pressed, the key setting is restored to the previously stored state. The configuration is such that each time the operation button group 28 or the control button group 29 is operated, the state thereof is stored in the EEPROM 307, and the key setting is made to the EEPROM 3 when the power is turned off.
