Description

  The present invention relates to an automatic transaction apparatus, an information notification method, and an information notification program capable of both information notification by lighting and image capturing.

  In a store of a financial institution, an automatic transaction device (ATM: Automated Teller Machine) that accepts a transaction operation from a user and discharges a medium such as a cash card or cash related to the transaction is arranged.

  In such an automatic transaction apparatus, the flicker lamp blinks (lights alternately with a lighting amount of 0% and a lighting amount of 100%), thereby informing the user of the discharge of the medium and guiding the user to the discharge port. Things have been done. In addition, an image of a user who has acquired a discharged medium for reasons such as crime prevention is captured and recorded by a camera (see, for example, Patent Document 1).

  By the way, in a camera attached to an automatic transaction apparatus, in order to capture an appropriate image, a change in ambient brightness (imaging) is usually adjusted by adjusting (adjusting) imaging settings such as an aperture value (F value). The exposure amount (exposure value) is kept (controlled) within a certain range from the reference value according to the environmental change.

[First embodiment]
FIG. 1 is a diagram showing the configuration of the automatic transaction apparatus according to the first embodiment. The automatic transaction apparatus 1 includes a light source unit 2 and an imaging unit 3.

  The light source unit 2 notifies information by turning on in an alternate lighting mode. In the alternate lighting mode, by changing the lighting amount gradually (gradual increase and decrease), the lighting state alternates between the first lighting state that is lit with the first lighting amount and the second lighting state that is lit with the second lighting amount. It is a mode to switch to. The second lighting amount is a lighting amount different from the first lighting amount. The gradual change will be described later with reference to FIG.

  For example, the first lighting amount is the lighting amount 0% (the light is turned off), and the second lighting amount is the lighting amount 100% (the lighted state with the maximum lighting amount). In this way, it is possible to make it easier for the user to perceive (perceive) information (better information can be reported) than when it is simply lit by lighting with different lighting amounts alternately.

  The imaging unit 3 adjusts imaging settings according to incident light that changes as the light source unit 2 is turned on. For example, as shown in FIGS. 1A and 1B, light emitted (irradiated) when the light source unit 2 is turned on is incident light partially incident on the imaging unit 3 due to reflection on the object 4 or the like. become. Therefore, in the first lighting state (FIG. 1A) that is lit with the first lighting amount and the second lighting state that is lit with the second lighting amount (FIG. 1B), the incident light is incident on the imaging unit 3. Light (for example, light amount) changes (is different).

  Therefore, for example, the imaging unit 3 corrects a deviation from a reference value (for example, a deviation from a preset appropriate exposure amount) caused by a change in incident light by adjusting (adjusting) the imaging setting. The imaging unit 3 images the object 4 while the light source unit 2 is lit in an alternate lighting manner.

In the following description, the exposure amount is corrected by adjusting the imaging settings. However, the present invention can be similarly applied to correction of other imaging parameters (for example, color tone correction).
Here, the gradual change will be described with reference to FIG. FIG. 2 is a diagram illustrating a relationship between a change in lighting amount and a change in exposure amount in the first embodiment. For the sake of explanation, it is assumed that the shutter speed (exposure time) is sufficiently small (for example, when an image is taken at time T1, the incident light quantity at time T1 is incident throughout the exposure time).

First, a conventional lighting mode will be described with reference to FIGS. 2 (a1) and 2 (a2).
FIG. 2 (a1) is a diagram showing the transition of the lighting amount when the light source unit 2 is lit in the conventional lighting mode. Specifically, lighting when the light source unit 2 switches between the first lighting state of the first lighting amount and the second lighting state of the second lighting amount by changing the lighting amount in a lump (at a time). It shows the transition of quantity. In FIG. 2 (a1), the vertical axis indicates the lighting amount and the horizontal axis indicates the time.

  FIG. 2 (a2) is a diagram showing the transition of the exposure amount when the transition of the lighting amount of the light source unit 2 is FIG. 2 (a1). FIG. 2A2 shows the exposure amount when it is assumed that a certain ratio (for example, all) of the light emitted from the light source unit 2 is incident according to the lighting amount. In FIG. 2 (a2), the vertical axis represents the exposure amount and the horizontal axis represents the time. The upper broken line is the overexposure (allowable upper limit exposure amount) set as the upper limit value of the exposure amount that can capture an appropriate image, and the lower broken line is set as the lower limit value of the exposure amount that can capture an appropriate image. The exposure underexposure (allowable lower limit exposure amount) is shown. That is, the range between the broken lines is an appropriate range (a range in which the exposure amount should be controlled).

  At time T1, the light source unit 2 switches the lighting amount from the first lighting amount (first lighting state) to the second lighting amount (second lighting state). Immediately before time T1, the imaging unit 3 adjusts so that the appropriate exposure amount (reference value) is obtained when the light source unit 2 is lit with the first lighting amount. For this reason, the amount of incident light also greatly increases due to a significant increase in the lighting amount at time T1, and the exposure amount is a value that greatly exceeds the appropriate exposure amount, that is, outside the appropriate range (a value that exceeds the allowable upper limit exposure amount). “Appropriate exposure + α”.

  Thereafter, the imaging unit 3 gradually decreases the exposure amount (for example, decreases by a predetermined amount per unit time) by adjusting the imaging setting, and keeps (controls) the exposure amount within an appropriate range at time T2, and then at time T3. To the same value as the appropriate exposure.

  At time T4, the light source unit 2 switches the lighting amount from the second lighting amount (second lighting state) to the first lighting amount (first lighting state). Immediately before time T4, the imaging unit 3 adjusts so that the appropriate exposure amount (reference value) is obtained when the light source unit 2 is lit with the second lighting amount. For this reason, the amount of incident light is also greatly reduced due to a significant decrease in the lighting amount at time T4, and the exposure amount is a value that is significantly less than the appropriate exposure amount, that is, outside the appropriate range (a value that is less than the allowable lower limit exposure amount). “Appropriate exposure -α”.

  Thereafter, the imaging unit 3 gradually increases the exposure amount (for example, increases by a predetermined amount per unit time) by adjusting the imaging setting, and keeps (controls) the exposure amount within an appropriate range at time T5, and then at time T6. To the same value as the appropriate exposure. Thereafter, this cycle (T1 to T6) is repeated.

  As described above, in the conventional lighting mode, the exposure amount is significantly shifted immediately after switching the lighting state (for example, between time T1 and T2 and between time T4 and T5) and falls outside the appropriate range, so that an appropriate image can be obtained. May not be able to be imaged.

Next, the lighting mode (alternate lighting mode) 1 of the present invention will be described with reference to FIGS. 2 (b1) and 2 (b2).
FIG. 2 (b1) is a diagram showing the transition of the lighting amount when the light source unit 2 is lit in the alternate lighting mode of the present invention. Specifically, lighting when the light source unit 2 switches between the first lighting state of the first lighting amount and the second lighting state of the second lighting amount by changing the lighting amount stepwise (gradually). It shows the transition of quantity. In FIG. 2 (b1), the vertical axis represents the lighting amount and the horizontal axis represents the time.

  FIG. 2 (b2) is a diagram showing the transition of the exposure amount when the transition of the lighting amount of the light source unit 2 is FIG. 2 (b1). FIG. 2B2 shows the exposure amount when it is assumed that a certain ratio (for example, all) of the light emitted from the light source unit 2 is incident according to the lighting amount. In FIG. 2 (b2), the vertical axis represents the exposure amount and the horizontal axis represents the time. The upper broken line indicates the overexposure (allowable upper limit exposure amount) set as the upper limit value of the exposure amount at which an appropriate image can be captured, and the lower broken line sets the lower limit value of the exposure amount at which an appropriate image can be captured. The exposure underexposure (allowable lower limit exposure amount) is shown. That is, the range between the broken lines is an appropriate range (a range in which the exposure amount should be controlled).

  At time T1, the light source unit 2 starts switching the lighting amount from the first lighting amount (first lighting state) to the second lighting amount (second lighting state), and sets the lighting amount to the first lighting amount and the second lighting amount. The third lighting amount is switched to the lighting amount between the two amounts. Immediately before time T1, the imaging unit 3 adjusts so that the appropriate exposure amount (reference value) is obtained when the light source unit 2 is lit with the first lighting amount. For this reason, the amount of incident light increases as the lighting amount increases at time T1, and the exposure amount is an overexposure value (the same value as the allowable upper limit exposure amount in the figure) “appropriate exposure amount + β (assuming β <α). "become.

Thereafter, the imaging unit 3 gradually decreases the exposure amount by adjusting the imaging setting (decreases the predetermined amount per unit time), and corrects it to the same value as the appropriate exposure amount at time T2.
At time T3, the light source unit 2 switches the lighting amount from the third lighting amount to the second lighting amount (second lighting state), and from the first lighting amount (first lighting state) to the second lighting amount (second lighting state). Switching the lighting amount to is finished. Immediately before time T3, the imaging unit 3 adjusts so that the appropriate exposure amount (reference value) is obtained when the light source unit 2 is lit with the third lighting amount. For this reason, the amount of incident light also increases due to the increase in the lighting amount at time T3, and the exposure amount is an overexposure value (the same value as the allowable upper limit exposure amount in the figure) “appropriate exposure amount + β (β <α). "become.

Thereafter, the imaging unit 3 gradually decreases the exposure amount by adjusting the imaging setting (decreases the predetermined amount per unit time), and corrects it to the same value as the appropriate exposure amount at time T4.
At time T5, the light source unit 2 starts switching the lighting amount from the second lighting amount (second lighting state) to the first lighting amount (first lighting state), and the lighting amount is changed to the first lighting amount and the second lighting amount. The third lighting amount is switched to the lighting amount between the two amounts. Immediately before time T5, the imaging unit 3 adjusts so that the appropriate exposure amount (reference value) is obtained when the light source unit 2 is lit with the second lighting amount. For this reason, the amount of incident light also decreases due to the decrease in the lighting amount at time T5, and the exposure amount is an underexposed value (the same value as the allowable lower limit exposure amount in the figure) “appropriate exposure amount−β (β <α. )"become.

Thereafter, the imaging unit 3 gradually increases the exposure amount by adjusting the imaging setting (increases by a predetermined amount per unit time), and corrects it to the same value as the appropriate exposure amount at time T6.
At time T7, the light source unit 2 switches the lighting amount from the third lighting amount to the first lighting amount (first lighting state), and from the second lighting amount (second lighting state) to the first lighting amount (first lighting state). Switching the lighting amount to is finished. Immediately before time T7, the imaging unit 3 adjusts so that the appropriate exposure amount (reference value) is obtained when the light source unit 2 is lit with the third lighting amount. For this reason, the amount of incident light also decreases due to the decrease in the lighting amount at time T7, and the exposure amount is an underexposed value (the same value as the allowable lower limit exposure amount in the figure) “appropriate exposure amount−β (β <α. )"become.

  Thereafter, the imaging unit 3 gradually increases the exposure amount by adjusting the imaging setting (increases by a predetermined amount per unit time), and corrects it to the same value as the appropriate exposure amount at time T8. Thereafter, this cycle (T1 to T8) is repeated.

  According to such a lighting mode, since the deviation (β <α) from the appropriate exposure amount caused by the change in the lighting amount when switching the lighting state can be reduced, the exposure amount falls within an appropriate range (controlled). The time can be lengthened. In particular, as shown in FIG. 2 (b2), the automatic transaction apparatus 1 lights up step by step with a change amount and a change timing (change interval) so that the exposure amount falls within an appropriate range immediately after changing the light amount. By changing the amount, you can control the amount of exposure so that it does not fall outside the proper range.

By turning on such an alternate lighting mode, the automatic transaction apparatus 1 can achieve both notification of information by lighting and imaging.
Next, the lighting mode (alternate lighting mode) 2 of the present invention will be described with reference to FIGS. 2 (c1) and 2 (c2).

  FIG. 2 (c1) is a diagram showing the transition of the lighting amount when the light source unit 2 is lit in the alternate lighting mode of the present invention. Specifically, when the light source unit 2 switches between the first lighting state of the first lighting amount and the second lighting state of the second lighting amount by gradually changing the lighting amount (predetermined amount per unit time). It shows the transition of lighting amount. In FIG. 2 (c1), the vertical axis represents the lighting amount and the horizontal axis represents the time.

  FIG. 2 (c2) is a diagram showing the transition of the exposure amount when the transition of the lighting amount of the light source unit 2 is FIG. 2 (c1). FIG. 2 (c2) shows the exposure amount when it is assumed that a certain ratio (for example, all) of the light emitted from the light source unit 2 is incident according to the lighting amount. In FIG. 2 (c2), the vertical axis represents the exposure amount and the horizontal axis represents the time. The upper broken line indicates the overexposure (allowable upper limit exposure amount) set as the upper limit value of the exposure amount at which an appropriate image can be captured, and the lower broken line sets the lower limit value of the exposure amount at which an appropriate image can be captured. The exposure underexposure (allowable lower limit exposure amount) is shown. That is, the range between the broken lines is an appropriate range (a range in which the exposure amount should be controlled).

  At time T1, the light source unit 2 starts switching the lighting amount from the first lighting amount (first lighting state) to the second lighting amount (second lighting state), and increases the lighting amount by a predetermined amount per unit time ( Start increasing at a predetermined lighting change amount).

  Immediately before time T1, the imaging unit 3 adjusts so that the appropriate exposure amount (reference value) is obtained when the light source unit 2 is lit with the first lighting amount. Therefore, when the lighting amount is increased by a predetermined lighting change amount from time T1, “the amount of exposure increase due to the increase in lighting amount (exposure increase speed) −the exposure correction amount due to adjustment of the imaging setting (exposure correction speed)”. The exposure amount gradually deviates from the appropriate exposure amount by the amount.

  The exposure amount increase (exposure increase speed) due to the increase in the lighting amount is an exposure amount that increases per unit time when the lighting amount is increased by a predetermined lighting change amount. The exposure correction amount (exposure correction speed) by adjusting the imaging setting is an exposure amount per unit time corrected by adjusting the imaging setting.

  The light source unit 2 increases the lighting amount by a predetermined amount per unit time from time T1 to time T2, and ends the increase of the lighting amount by a predetermined amount per unit time when the lighting amount reaches the second lighting amount. At this time, when the lighting amount is switched from the first lighting amount (first lighting state) to the second lighting amount (second lighting state), the deviation of the exposure amount from the appropriate exposure amount is maximized. Specifically, the exposure amount becomes “appropriate exposure amount + γ (assuming γ <α)”, which is an overexposed value.

Thereafter, the imaging unit 3 gradually decreases the exposure amount by adjusting the imaging setting (decreases by a predetermined change amount per unit time), and corrects it to the same value as the appropriate exposure amount at time T3.
At time T4, the light source unit 2 starts switching the lighting amount from the second lighting amount (second lighting state) to the first lighting amount (first lighting state), and decreases the lighting amount by a predetermined amount per unit time ( Decrease with a predetermined lighting change amount).

  Immediately before time T4, the imaging unit 3 adjusts so that the appropriate exposure amount (reference value) is obtained when the light source unit 2 is lit with the second lighting amount. Therefore, if the lighting amount is decreased by a predetermined lighting change amount from time T4, “exposure reduction amount due to reduction of lighting amount (exposure reduction speed) −exposure correction amount by adjusting imaging setting (exposure correction speed)” The exposure amount gradually deviates from the appropriate exposure amount by the amount.

The exposure amount reduction (exposure reduction speed) due to the reduction in lighting amount is an exposure amount that decreases per unit time when the lighting amount is reduced by a predetermined lighting change amount.
The light source unit 2 decreases the lighting amount by a predetermined amount per unit time from time T4 to time T5. When the lighting amount reaches the first lighting amount, the light source unit 2 ends the decrease of the lighting amount by a predetermined amount per unit time. At this time, when the lighting amount is switched from the second lighting amount (second lighting state) to the first lighting amount (first lighting state), the deviation of the exposure amount from the appropriate exposure amount is maximized. Specifically, the exposure amount becomes “appropriate exposure amount−γ (assuming γ <α)”, which is an underexposed value.

  Thereafter, the imaging unit 3 adjusts the imaging settings to gradually increase the exposure amount (increase by a predetermined change amount per unit time), and correct to the same value as the appropriate exposure amount at time T6. Thereafter, this cycle (T1 to T6) is repeated.

  According to such a lighting mode, since the deviation (γ <α) from the appropriate exposure amount caused by the change in the lighting amount when switching the lighting state can be reduced, the exposure amount falls within the appropriate range (controlled). The time can be lengthened. In particular, as shown in FIG. 2 (c2), the automatic transaction apparatus 1 changes the lighting amount by a predetermined amount per unit time so that the exposure amount falls within the appropriate range, so that the exposure amount is out of the appropriate range. It can be controlled so that it does not become.

By turning on such an alternate lighting mode, the automatic transaction apparatus 1 can achieve both notification of information by lighting and imaging.
More preferably, the automatic transaction apparatus 1 may change the lighting amount by a predetermined amount per unit time so that the exposure correction speed becomes faster than the exposure increase speed (exposure decrease speed). When the exposure correction speed is faster, the deviation from the appropriate exposure amount caused by the change in the lighting amount is corrected at any time (immediately). Therefore, the automatic transaction apparatus 1 can suppress the deviation of the exposure amount from the appropriate exposure amount.

Here, the outline of the second embodiment will be described. FIG. 5 is a cross-sectional view of the main part of the ATM in the second embodiment. Specifically, it is a cross-sectional view around the bill deposit / withdrawal unit 103.
In ATM100, user guidance part 105a guides user 210 to bill depositing / withdrawing part 103 by switching two lighting states alternately. When the guided user 210 acquires the banknote 200 or inserts the banknote 200, the imaging unit 106a captures an image of the user 210. That is, in the ATM 100, the user guide 105a captures an image of the user 210 while the user guide unit 105a is lit by alternately switching between two lighting states to guide the user 210.

  By the way, in ATM100, as shown in FIG. 5, since some light radiate | emitted from the user guidance part 105a is reflected by the user 210 grade | etc., And advances to the imaging part 106a, the user guidance part 105a is lighted. Incident light (for example, intensity of incident light (incident light amount)) that enters the imaging unit 106a changes according to the amount.

  Therefore, if the user guidance unit 105a changes the lighting amount rapidly when switching the lighting state, the incident light changes significantly, and the exposure amount deviates significantly from the preset reference value of the exposure amount. . As a result, the imaging unit 106a cannot capture an appropriate image until the exposure amount is controlled again within a certain range from the reference value by exposure correction.

Therefore, when the user guidance unit 105a switches the lighting state, the lighting amount is gradually changed to prevent the user guidance unit 105a from significantly deviating from the reference value of the exposure amount.
Next, functions provided in the ATM 100 will be described. FIG. 6 is a diagram showing ATM functional blocks in the second embodiment.

The ATM 100 includes a medium control unit 100a, a lighting mode management unit 100b, a guidance control unit 100c, and an imaging control unit 100d.
The medium control unit 100a controls taking in various media (receipt, card, banknote) into the apparatus and discharging from the apparatus. For example, when discharging the banknote, the medium control unit 100a causes the banknote processing unit 130 to take out the banknote from the banknote storage unit, transport the banknote to the banknote deposit / withdrawal unit 103, and release the shutter after the transport is completed. The banknote is made available to the user. And the medium control part 100a makes the banknote processing unit 130 close a shutter after completion of acquisition of the banknote by a user.

  The lighting mode management unit 100b manages the lighting mode (guidance mode). The first lighting mode, which is a lighting mode used for guidance during a period when there is no possibility of imaging, and the second lighting mode, which is a lighting mode used for guidance during a period when there is a possibility of imaging, are managed. .

  In the first lighting mode, the lighting state of the lighting amount 0 (first lighting state) and the lighting state of the lighting amount 100 (second lighting state) are alternately switched at predetermined intervals by changing the lighting amount at once. It is a mode that lights up. In the second lighting mode, the lighting amount is changed stepwise (in increments of 25), so that the lighting state with the lighting amount 0 (first lighting state) and the lighting state with the lighting amount 100 (second lighting state) are set at predetermined intervals. It is a mode in which the light is switched alternately every time. Each lighting mode will be described later in detail with reference to FIG.

  The guidance control unit 100c controls the guidance of the user to the medium insertion destination and medium ejection destination. For example, when the medium control unit 100a discharges banknotes, the guidance control unit 100c causes the guidance processing unit 150a to turn on the user guidance unit 105a in the lighting mode managed by the lighting mode management unit 100b, and Guide to banknote deposit / withdrawal unit 103.

  The imaging control unit 100d controls imaging of the user's image. The imaging control unit 100d causes the imaging processing unit 117 to capture an image of the user using the imaging unit 106a or the imaging unit 106b, according to the progress of medium intake / discharge. For example, when the medium control unit 100a discharges the banknote, the image pickup control unit 100d picks up the image pickup processing unit 117 when the medium control unit 100a detects an operation of acquiring the discharged banknote (acquisition of the banknote by the user). The image of the user is captured using the unit 106a.

  Here, the structure of the guidance processing unit 150a capable of changing the lighting amount in steps (in increments of 25) will be described. FIG. 7 is a circuit diagram of the guidance processing unit in the second embodiment.

  The guidance processing unit 150a includes a control unit 150a1 and a user guidance unit (light source) 105a. User guidance part 105a has LED1, LED2, LED3, and LED4. One end of the LED 1 is connected to the constant voltage source V, and the other end is connected to the ground (GND) via the resistor R1 and the transistor Tr1. One end of the LED 2 is connected to the constant voltage source V, and the other end is connected to the ground (GND) via the resistor R2 and the transistor Tr2.

  One end of the LED 3 is connected to the constant voltage source V, and the other end is connected to the ground (GND) via the resistor R3 and the transistor Tr3. One end of the LED 4 is connected to the constant voltage source V, and the other end is connected to the ground (GND) via the resistor R4 and the transistor Tr4. In the following, the lighting amount of each LED is the same (lighting amount is 25), the lighting amount of the user guiding unit 105a when all the LEDs are turned on is 100, and the user guiding unit 105a when all the LEDs are turned off. The lighting amount is set to zero.

  The control unit 150a1 controls the guidance processing unit 150a based on an instruction from the guidance control unit 100c. Specifically, the control unit 150a1 controls (turns on and off) the transistors Tr1, Tr2, Tr3, and Tr4 based on an instruction from the guidance control unit 100c, thereby changing the lighting state of the user guidance unit 105a to the lighting amount 100. The lighting state and the lighting state with a lighting amount of 0 are alternately switched.

  When the controller 150a1 turns on the transistor Tr1, a current flows through the LED 1, and the LED 1 is lit with a lighting amount corresponding to the current. On the other hand, when the control unit 150a1 turns off the transistor Tr1, no current flows through the LED 1, and the LED 1 is turned off. When the controller 150a1 turns on the transistor Tr2, a current flows through the LED 2, and the LED 2 is lit with a lighting amount corresponding to the current. On the other hand, when the control unit 150a1 turns off the transistor Tr2, no current flows through the LED 2, and the LED 2 is turned off.

  When the control unit 150a1 turns on the transistor Tr3, a current flows through the LED 3, and the LED 3 is lit with a lighting amount corresponding to the current. On the other hand, when the control unit 150a1 turns off the transistor Tr3, no current flows through the LED 3, and the LED 3 is turned off. When the control unit 150a1 turns on the transistor Tr4, a current flows through the LED 4, and the LED 4 is lit with a lighting amount corresponding to the current. On the other hand, when the control unit 150a1 turns off the transistor Tr4, no current flows through the LED 4, and the LED 4 is turned off.

  In this way, the control unit 150a1 can individually turn on / off each LED constituting the user guiding unit 105a by turning on / off each transistor, so that the lighting amount of the user guiding unit 105a is set to 5 It can be controlled in stages (0, 25, 50, 75, 100).

  Thus, the control unit 150a1 alternates the lighting state of the user guidance unit 105a between a lighting state with a lighting amount of 0 (first lighting state) and a lighting state with a lighting amount of 100 (second lighting state) at predetermined intervals. When switching to, the lighting amount can be changed step by step (in increments of 25).

Next, user guidance and user imaging will be described using banknote discharge processing. FIG. 8 is a flowchart of the banknote discharge process in the second embodiment.
[Step S <b> 11] The medium control unit 100 a causes the banknote processing unit 130 to take out a banknote from the banknote storage unit, and causes the banknote depositing / withdrawing unit 103 to start conveyance by the conveyance mechanism.

  [Step S12] The guidance control unit 100c starts guidance to the banknote deposit and withdrawal unit 103. The guidance control unit 100c acquires, from the lighting mode management unit 100b, a first lighting mode that is a lighting mode used for guidance in a period during which there is no possibility of imaging (period in which bills are in the apparatus). In the first lighting mode, the user guidance unit 105a is turned on by the guidance processing unit 150a.

  [Step S13] The medium control unit 100a determines whether or not the preparation for discharging the banknote from the banknote depositing and dispensing unit 103 is completed. The medium control unit 100a determines that the preparation for discharging the banknote is completed when the conveyance of the banknote to the banknote depositing / dispensing unit 103 is completed.

  When the medium control unit 100a determines that the preparation for discharging the banknote is completed, the process proceeds to step S14, and when it is determined that the preparation for discharging the banknote is not completed, the preparation for discharging the banknote is completed. stand by.

  [Step S14] The guidance control unit 100c is a second lighting that is a lighting mode used for guidance during a period during which imaging may be performed (period after the banknote is discharged from the apparatus) from the lighting mode management unit 100b. A mode is acquired and the lighting mode used for guidance is switched from the first lighting mode to the second lighting mode.

[Step S15] The medium control unit 100a causes the banknote processing unit 130 to open the shutter of the banknote deposit / withdrawal unit 103 so that the user can acquire the banknotes.
[Step S16] The medium control unit 100a determines whether or not a user's bill acquisition operation has been detected. For example, the medium control unit 100 a detects a user's bill acquisition operation by a sensor or the like provided in the bill deposit / withdrawal unit 103.

  When it is determined that the user's banknote acquisition operation is detected, the medium control unit 100a proceeds to step S17, and when it is determined that the user's banknote acquisition operation is not detected, the medium control unit 100a performs the user's banknote acquisition operation. Wait until it is detected.

[Step S17] The imaging control unit 100d causes the imaging processing unit 117 to capture an image of the user using the imaging unit 106a.
[Step S18] The medium control unit 100a determines whether or not all the banknotes conveyed to the banknote deposit and withdrawal unit 103 have been taken out. For example, the medium control unit 100a detects the acquisition status of banknotes using a sensor or the like provided in the banknote deposit / withdrawal unit 103, and determines whether or not all the conveyed banknotes have been taken out.

  When the medium control unit 100a determines that all the banknotes conveyed to the banknote deposit / withdrawal unit 103 have been taken out, the process proceeds to step S19, and when it is determined that all the banknotes conveyed to the banknote deposit / withdrawal unit 103 have not been taken out. Proceed to step S16.

  [Step S19] The guidance control unit 100c ends the guidance to the banknote deposit and withdrawal unit 103. The guidance control unit 100c causes the guidance processing unit 150a to finish turning on the user guidance unit 105a (the user guidance unit 105a is turned off).

  Next, the first lighting mode, which is a lighting mode used for guidance when there is no possibility of imaging, and the second lighting mode, which is a lighting mode used for guidance when there is a possibility of imaging, will be described. To do. FIG. 9 is a diagram illustrating a relationship between a change in lighting amount and a change in exposure amount in the second embodiment.

  Fig.9 (a) is a figure which shows transition of the lighting amount at the time of guiding a user in the discharge processing of a banknote. Specifically, the transition of the lighting amount when the user guidance unit 105a is lit in the first lighting mode until completion of preparation for discharge and is turned on in the second lighting mode after completion of preparation for discharge is shown. In FIG. 9A, the vertical axis represents the lighting amount and the horizontal axis represents the time.

  FIG. 9B is a diagram illustrating a change in the exposure amount when the change in the lighting amount of the user guidance unit 105a is that in FIG. 9A. FIG. 9B shows the transition of the exposure amount when it is assumed that a certain ratio (for example, all) of the emitted light emitted from the user guide 105a is incident according to the lighting amount. In FIG. 9B, the vertical axis represents the exposure amount and the horizontal axis represents the time. Further, the upper broken line indicates an overexposure (allowable upper limit exposure amount) that is set in advance as an upper limit value of an exposure amount that allows an appropriate image to be captured, and the lower broken line indicates an exposure amount that allows an appropriate image to be captured. A preset underexposure (allowable lower limit exposure) is shown. That is, the range between the broken lines is a preset appropriate range (a range in which the exposure amount is to be controlled).

When the medium control unit 100a starts conveying bills at time T1 (step S11), the guidance control unit 100c starts to guide the user in the first lighting mode (step S12).
When the guidance control unit 100c starts lighting in the first lighting mode at time T1, the guidance control unit 100c starts switching the lighting state of the user guiding unit 105a (switching from the first lighting state to the second lighting state). The lighting amount of the unit 105a is switched at once from the lighting amount 0 to the lighting amount 100.

  Immediately before time T1, the imaging unit 106a adjusts so that when the lighting amount of the user guidance unit 105a is 0, the appropriate exposure amount (reference value) is obtained. Therefore, by increasing the lighting amount by 100 at time T1, the amount of incident light is greatly increased, and the exposure amount is a value significantly exceeding the appropriate exposure amount, that is, outside the appropriate range (a value exceeding the allowable upper limit exposure amount). It becomes a certain “appropriate exposure amount + α”.

Thereafter, the imaging unit 106a gradually decreases the exposure amount (for example, a predetermined amount per unit time) by adjusting the imaging setting, and corrects the exposure value to the same value as the appropriate exposure amount at time T2.
The guidance control unit 100c starts switching the lighting state of the user guiding unit 105a (switching from the second lighting state to the first lighting state) at time T3 which is the switching timing of the lighting state, and the user guiding unit 105a The lighting amount is switched from the lighting amount 100 to the lighting amount 0 at once.

  Immediately before time T3, the imaging unit 106a adjusts so that when the lighting amount of the user guidance unit 105a is the lighting amount 100, the appropriate exposure amount is obtained. Therefore, when the lighting amount is reduced by 100 at time T3, the amount of incident light is greatly reduced, and the exposure amount is a value that is significantly less than the appropriate exposure amount, that is, outside the appropriate range (a value that is less than the allowable lower limit exposure amount). It becomes a certain “appropriate exposure amount−α”.

Thereafter, the imaging unit 106a gradually increases the exposure amount (for example, increases by a predetermined amount per unit time) by adjusting the imaging setting, and corrects it to the same value as the appropriate exposure amount at time T4.
When the medium control unit 100a completes preparation for discharge at time T5 (step S13: Yes), the guidance control unit 100c switches the lighting mode to the second lighting mode (step S14).

  The guidance control unit 100c starts switching the lighting state of the user guiding unit 105a (switching from the first lighting state to the second lighting state) at time T6 which is the switching timing of the lighting state, and the user guiding unit 105a Is switched from 0 to 25.

  Immediately before time T6, the imaging unit 106a adjusts so that the appropriate exposure amount is obtained when the lighting amount of the user guidance unit 105a is zero. Therefore, when the lighting amount increases by 25 at time T6, the amount of incident light increases, and the exposure amount becomes “appropriate exposure amount + β (β <α)” which is an overexposed value.

Thereafter, the imaging unit 106a gradually decreases the exposure amount by adjusting the imaging setting (decreases the predetermined amount per unit time), and corrects it to the same value as the appropriate exposure amount at time T7.
The guidance control unit 100c switches the lighting amount of the user guidance unit 105a from the lighting amount 25 to the lighting amount 50 at time T8 after a predetermined time has elapsed from time T7.

  Immediately before time T8, the imaging unit 106a adjusts so that when the lighting amount of the user guidance unit 105a is the lighting amount 25, the appropriate exposure amount is obtained. Therefore, when the lighting amount increases by 25 at time T8, the amount of incident light increases, and the exposure amount becomes “appropriate exposure amount + β (β <α)”, which is an overexposed value.

Thereafter, the imaging unit 106a gradually decreases the exposure amount by adjusting the imaging setting (decreases the predetermined amount per unit time), and corrects it to the same value as the appropriate exposure amount at time T9.
The guidance control unit 100c switches the lighting amount of the user guidance unit 105a from the lighting amount 50 to the lighting amount 75 at time T10 after a predetermined time has elapsed from time T9.

  Immediately before time T10, the imaging unit 106a adjusts so that when the lighting amount of the user guidance unit 105a is the lighting amount 50, the appropriate exposure amount is obtained. Therefore, when the lighting amount increases by 25 at time T10, the incident light amount increases, and the exposure amount becomes “appropriate exposure amount + β (β <α)”, which is an overexposed value.

Thereafter, the imaging unit 106a gradually decreases the exposure amount by adjusting the imaging setting (decreases the predetermined amount per unit time), and corrects it to the same value as the appropriate exposure amount at time T11.
The guidance control unit 100c switches the lighting amount of the user guidance unit 105a from the lighting amount 75 to the lighting amount 100 at the time T12 after a predetermined time has elapsed from the time T11, and switches from the first lighting state to the second lighting state. End switching.

  Immediately before time T12, the imaging unit 106a adjusts so that when the lighting amount of the user guiding unit 105a is the lighting amount 75, the appropriate exposure amount is obtained. Therefore, when the lighting amount increases by 25 at time T12, the amount of incident light increases, and the exposure amount becomes “appropriate exposure amount + β (β <α)”, which is an overexposed value.

Thereafter, the imaging unit 106a gradually decreases the exposure amount by adjusting the imaging setting (decreases the predetermined amount per unit time), and corrects it to the same value as the appropriate exposure amount at time T13.
The guidance control unit 100c starts switching the lighting state of the user guiding unit 105a (switching from the second lighting state to the first lighting state) at time T14, which is the switching timing of the lighting state, and the user guiding unit 105a. Is switched from the lighting amount 100 to the lighting amount 75.

  Immediately before time T14, the imaging unit 106a adjusts so that when the lighting amount of the user guidance unit 105a is the lighting amount 100, the appropriate exposure amount is obtained. Therefore, when the lighting amount decreases by 25 at time T14, the amount of incident light decreases, and the exposure amount becomes “appropriate exposure amount−β (β <α)”, which is an underexposed value.

After that, the imaging unit 106a gradually increases the exposure amount (increases by a predetermined amount per unit time) by adjusting the imaging setting, and corrects it to the same value as the appropriate exposure amount at time T15.
The guidance control unit 100c switches the lighting amount of the user guidance unit 105a from the lighting amount 75 to the lighting amount 50 at time T16 after a predetermined time has elapsed from time T15.

  Immediately before time T16, the imaging unit 106a adjusts so that the appropriate exposure amount is obtained when the lighting amount of the user guiding unit 105a is the lighting amount 75. Therefore, when the lighting amount decreases by 25 at time T16, the amount of incident light decreases, and the exposure amount becomes “appropriate exposure amount−β (β <α)”, which is a value that seems to be underexposed.

Thereafter, the imaging unit 106a gradually increases the exposure amount (increases by a predetermined amount per unit time) by adjusting the imaging setting, and corrects it to the same value as the appropriate exposure amount at time T17.
The guidance control unit 100c switches the lighting amount of the user guidance unit 105a from the lighting amount 50 to the lighting amount 25 at time T18 after a predetermined time has elapsed from time T17.

  Immediately before time T18, the imaging unit 106a adjusts so that the appropriate exposure amount is obtained when the lighting amount of the user guide unit 105a is the lighting amount 50. Therefore, when the lighting amount decreases by 25 at time T18, the amount of incident light decreases, and the exposure amount becomes “appropriate exposure amount−β (β <α)”, which is an underexposed value.

After that, the imaging unit 106a gradually increases the exposure amount (by a predetermined amount per unit time) by adjusting the imaging setting, and corrects it to the same value as the appropriate exposure amount at time T19.
The guidance control unit 100c switches the lighting amount of the user guidance unit 105a from the lighting amount 25 to the lighting amount 0 at a time T20 after a predetermined time has elapsed from the time T19, and switches from the second lighting state to the first lighting state. End switching.

  Immediately before time T20, the imaging unit 106a adjusts so that when the lighting amount of the user guidance unit 105a is the lighting amount 50, the appropriate exposure amount is obtained. Therefore, when the lighting amount decreases by 25 at time T20, the amount of incident light decreases, and the exposure amount becomes “appropriate exposure amount−β (β <α)” which is an underexposed value.

Thereafter, the imaging unit 106a gradually increases the exposure amount (increases by a predetermined amount per unit time) by adjusting the imaging setting, and corrects it to the same value as the appropriate exposure amount at time T21.
Thereafter, this cycle (T6 to T21) detects a banknote acquisition operation (step S16: Yes), takes an image of the user (step S17), and determines that all of the conveyed banknotes have been taken out (step S18: Repeat until Yes).

  According to such a lighting mode, the deviation (β <α) from the appropriate exposure amount caused by the change in the lighting amount when the lighting state is switched can be reduced during a period in which an image is likely to be captured. Therefore, it is possible to lengthen the time during which the exposure amount falls within the appropriate range (controlled). In particular, as shown in FIG. 9, the lighting amount is changed step by step with the number of changes, the amount of change, and the change timing (change interval) so that the exposure amount falls within the appropriate range even after the lighting amount is changed. With this, you can control the amount of exposure so that it is not outside the proper range.

By lighting in such a lighting mode, the automatic transaction apparatus 1 can capture an appropriate image even when the information is reported by alternately lighting with different lighting amounts.
In addition, in the period when the image is not captured (period in which the banknote is in the apparatus), by switching the lighting amount at once and switching the lighting state, the change between light and dark is made clearer than in the case of the second lighting mode, It is easy for the user to perceive (perceive) (information can be reported well).

  In the second lighting mode, when the lighting amount is changed stepwise, after the predetermined amount of time has elapsed after the exposure amount is corrected to the same value as the appropriate exposure amount, the lighting amount is changed to the next step. Not limited to this. It is only necessary to change the lighting amount in steps so that the exposure amount does not fall outside the appropriate range.For example, after the exposure amount is corrected to the same value as the appropriate exposure amount, the lighting amount is immediately changed to the next step. Alternatively, the lighting amount may be changed to the next stage before the exposure amount is corrected to the same value as the appropriate exposure amount.

  In addition, the length of time during which lighting is performed in the first lighting state (lighting amount 0) and the second lighting state (lighting amount 100) in the second lighting state is referred to as the first lighting state (lighting amount 0) in the first lighting state. You may make it the same length as the length of time to light in a 2nd lighting state (lighting quantity 100).

Moreover, even if the difference in the lighting amount between the first lighting state and the second lighting state in the second lighting mode is smaller than the difference in the lighting amount between the first lighting state and the second lighting state in the second lighting mode. Good.
For example, in the second lighting mode, the lighting amount in the first lighting state can be set to 0, and the lighting amount in the second lighting state can be set to the lighting amount 75. Thus, by making the difference in the lighting amount between the first lighting state and the second lighting state smaller, it is possible to further prevent the exposure amount from being outside the proper range in the second lighting mode.

Note that the appropriate range can be changed as appropriate according to the required accuracy of the image. For example, when a highly accurate image is required, the appropriate range may be set narrower.
