Description

Imaging system, imaging method, camera adapter, and program

The present invention relates to a technique for measuring a skin condition.

The skin condition is optically measured. In particular, when a lens adapter attached to a general-purpose smartphone is used, it is possible to construct a shooting environment for performing skin measurement easily. In this case, since the shooting function and lighting function of the smartphone are used, if the minimum optical module is installed, the lens adapter side does not require a power source, and a shooting environment for skin shooting can be realized at low cost. .

JP2013-257518A

* Shooting functions such as LED modules built into smartphones may not be sufficient for skin measurement. Moreover, since the performance of a camera differs also with a smart phone, even if it uses the same lens adapter, if a smart phone differs, a difference will appear in the quality of a picked-up image. As a result, the reliability of the skin condition determination result cannot be guaranteed.

Furthermore, the skin (skin) state has various elements such as texture, dirt, and spots, and in order to know the skin state in more detail, it is preferable to measure based on a plurality of viewpoints. However, the optimum optical arrangement usually varies depending on the viewpoint. The optical arrangement is typically defined by a combination of incident light wavelength, change, intensity, and received light (polarization state, intensity, wavelength of reflected or scattered light). For example, it is preferable to construct an optical arrangement that uses white light as incident light and can receive only reflected light having the same polarization state as the incident light for the so-called texture (skin surface condition). .

From this viewpoint, it is conceivable to provide a lens adapter with a mechanism capable of switching a plurality of optical arrangement patterns in accordance with the measurement purpose in order to obtain detailed information on the skin condition. However, even if such a mechanism is provided, it is necessary for the user to perform the switching operation of the optical arrangement of the adapter and the photographing execution operation a plurality of times (for example, three times according to the purpose of texture, dirt, and stain). It takes. In addition, during this series of measurements, it is difficult to maintain a constant distance from the measurement target region (for example, near the nose or cheek) and the lens adapter to the skin. Variations in the target region and distance contribute to lower skin condition determination accuracy.

Regarding the cooperation between the control of the portable photographing device and the setting of the optical arrangement in the camera attachment, Document 1 starts the portable photographing device in conjunction with the detection of the flash in the attachment of the portable photographing device that does not have the flash function. It is described to do. In the invention of Document 1, if the user operates the portable imaging device, there is no need to perform any special operation on the attachment, and flash photography can be realized. However, it is impossible to realize a plurality of optical arrangement patterns in order to measure the skin condition from various viewpoints.

As described above, in the prior art, it is difficult to easily obtain detailed information about the skin.
An object of this invention is to obtain the detailed information about skin easily.

In one aspect, the present invention provides an attachment portion for attachment to an imaging device, an optical system that guides at least received light to the imaging device, a reception portion that receives a control signal from the imaging device, and the reception portion. And a controller that adjusts the optical system based on the received control signal.

According to the present invention, detailed information about the skin can be obtained easily.

FIG. 4 shows an operation example of the camera adapter 100 and the smartphone 200. First, the user operates the smartphone 200 and activates an application program (hereinafter referred to as an application) for controlling the camera adapter 100. Then, information for specifying measurement contents (types of measurement items and execution order thereof) (hereinafter referred to as setting information) is input or read from the storage unit 220, and an instruction to start imaging is input (S501). At this time, a guidance screen as shown in FIG. 5A may be displayed on the smartphone 200.
In addition to the measurement items, the measurement execution order may be specified by the user. Alternatively, the control unit 250 may determine according to a predetermined algorithm according to a plurality of designated measurement items.
Further, after that, a guidance screen as shown in FIG. 5B may be displayed. Further, during measurement, guidance as shown in FIG. 5C may be displayed.

Hereinafter, the case where the setting information specifies that three types of optical measurements and two types of non-optical measurements are performed will be described as an example.

Based on the setting information, the smartphone 200 transmits a control signal indicating a mode to be executed first to the camera adapter 100 (S503). Here, it is assumed that the first mode is designated. The camera adapter 100 performs setting or switching of the optical arrangement of the optical system 110 according to this control signal, waits for a predetermined period (for example, 0.5 seconds) (S505), and confirms that the preparation for photographing is ready. A signal ACK is transmitted to the smartphone 200 (S507). The reason for waiting for a predetermined period is to perform processing for the optical module to exhibit optimum performance, such as preheating the light source.

The smartphone 200 executes the image capturing upon receipt of the confirmation signal ACK and stores the generated image data (S509). Subsequently, in order to execute the next measurement item according to the setting information, the smartphone 200 transmits a mode switching command to the camera adapter 100 (S511). Upon receiving the switching command, the camera adapter 100 performs mode switching and necessary standby (S513), and transmits a confirmation signal ACK to the smartphone 200 when preparation for measurement is completed (S515). When receiving the confirmation signal ACK, the smartphone 200 performs imaging in the second mode and stores the image data (S517).

Subsequently, a switching command is transmitted to the camera adapter 100 to perform the next shooting according to the setting information (S519). Similarly, the camera adapter 100 performs mode switching and necessary standby (S521), and transmits a confirmation signal ACK to the smartphone 200 when preparation is completed (S523). The smartphone 200 that has received the confirmation signal ACK performs imaging in the third mode and stores image data (S525).
Subsequently, 200 determines that the next measurement item is water content measurement according to the setting information, and transmits a water content measurement command to the camera adapter 100 (S527). Upon receiving the moisture content measurement command, the camera adapter 100 performs moisture content measurement (S529), and transmits the measurement result data to the smartphone 200 (S531). The smartphone 200 stores the received measurement data (S533).

Subsequently, the smartphone 200 transmits an elasticity measurement command to the camera adapter 100 according to the setting information (S535). Upon receiving the elasticity measurement command, the camera adapter 100 performs elasticity measurement (S537), and transmits the measurement result data to the smartphone 200 (S539). The smartphone 200 stores the received measurement data (S541).

When the smartphone 200 determines that the measurement of all items has been completed based on the setting information, the smartphone 200 analyzes the measurement data acquired in a series of measurements, processes and edits as necessary, and displays the measurement results on the screen ( S543). Note that the user may be notified of the end of measurement by displaying a screen as shown in FIG. Note that the end notification may be performed using voice or vibration.

FIG. 5E is an example of the display of the measurement result. In this example, the skin condition is scored for each measurement item, and a comprehensive index (score) is shown in the chart.

According to the above-described embodiment, when the control application is activated on the smartphone 200, the control of the camera adapter 100 (change in optical arrangement) and the control of the smartphone 200 (shooting execution timing) are performed in conjunction. As a result, even when a plurality of types of measurements are included in a series of measurements, the user does not need to perform a switching operation. This makes it possible to acquire detailed skin information based on the results of a plurality of types of optical measurements, which was difficult to acquire with a general-purpose imaging device. In addition, there is no fear that the switching operation is unnecessary or the determination accuracy is lowered due to camera shake. Moreover, since it can implement | achieve by attaching the camera adapter 100 to a general purpose portable terminal, it is easy.
Furthermore, by using a non-optical measurement method in combination with optical measurement, it is possible to acquire information about skin that cannot be acquired by a general-purpose information communication terminal device having a camera function.

Based on the fact that the state of the skin may differ depending on the location, a plurality of sites may be measured.
Specifically, when setting information is generated before the start of measurement, a screen as shown in FIG. 5F is displayed, and the user is allowed to specify a measurement target region and a measurement order. In this example, the position and the order can be specified by specifying the positions of the objects OB21 to OB24.
When measuring a plurality of parts with the same measurement item, a screen as shown in FIG. 5G is displayed, or guidance is given to adjust the position to which 100 is applied and confirm the position by a voice message. May be.
When a plurality of parts are measured, the evaluation of each item may be displayed for each part as shown in FIG. In the figure, an object OB1 representing a face and OB2 to OB4 corresponding to three measurement sites are displayed, and the evaluation is expressed as a score.

In short, a camera adapter according to the present invention includes an attachment portion for attachment to an imaging device, an optical system that guides at least received light to the imaging device, a reception portion that receives a control signal from the imaging device, and the reception portion. And a control unit that adjusts the optical system based on the received control signal.

The second communication unit 342 is a communication module for transferring data measured by the scope camera 300 to the PC 400 using the communication cable 500 according to a communication standard such as USB or Ethernet. Realized as a connection terminal.
The first communication unit 341 and the second communication unit 342 may be wired communication or wireless communication, respectively, but at least the skin image data generated by the imaging unit 360 is transmitted via the second communication unit 342. Sent. Therefore, it is preferable that the second communication unit 342 has a higher capability in data transfer speed and transfer amount than the first communication unit 341.

The imaging unit 360 includes a light source group 361, a lens 362, a light receiving element 363, an imaging control unit 364, an image processing unit 365, and a filter group 366, and has a plurality of switchable optical systems. In one example, the imaging unit 360 has a function equivalent to that obtained by integrating the imaging unit 210 and the optical system 110. In short, it is sufficient that a plurality of measurement modes are facilitated and can be switched by the user.

The control unit 350 instructs the light source group 361 and the filter group 366 to set and change the setting, and instructs the imaging control unit 364 and the lens 362 to perform imaging.

The notification unit 390 is realized by a light emitting device such as an LED, a liquid crystal display, or the like, and notifies the user that a mode switching command has been received from the PC 400.

The storage unit 380 is a storage device such as a semiconductor memory, and stores setting information.

The water content measuring unit 320 has the same function as the water content measuring unit 120. The elasticity measuring unit 330 has the same function as the elasticity measuring unit 130.

That is, it can be understood that the scope camera 300 has a configuration in which the camera adapter 100 is added with an imaging function of the smartphone 200, a function of accepting a user operation, and a two-system communication function.

The PC 400 is a general-purpose PC, for example. The PC 400 includes a first communication unit 411, a second communication unit 412, a control unit 440, a storage unit 430, and a display unit 420.
The first communication unit 411 is a communication module for exchanging information related to control with the scope camera 300 in accordance with a communication standard such as WiFi or Bluetooth (registered trademark). Specifically, 441 transmits an operation signal and transmits a confirmation signal ACK to the scope camera 300.

The display unit 420 is a display, and is used for input and reading of setting information, notification of processing status being executed, display of measurement results, and the like. The storage unit 430 is a hard disk or a semiconductor and stores setting information and measurement data. The control unit 440 is a processor, and performs processing such as analysis / editing on the measurement data to generate drawing data.
The input unit 450 is a keyboard or a mouse, and is used by a user to input setting information.

FIG. 8 shows an operation example of the measurement system 20. In addition, the broken line of the figure shows that the communication is wireless, and the solid line shows that the communication is wired.
The user reads the setting information by operating the PC 400 to activate a predetermined application. The PC 400 is in a state of receiving an operation signal from the scope camera 300 (S600). Next, when the user operates the switch 370 to perform an operation for starting measurement (S601), an operation signal is transmitted to the PC 400 via the first communication unit 341 (S603). Since the PC 400 has received the operation signal for the first time, it is determined that the measurement based on the setting information has started.

The scope camera 300 executes shooting by applying the mode specified by the user using the switch 370 (S605). When shooting is completed, the image data image is transmitted to the PC 400 via the second communication unit 342 (S607).
The PC 400 recognizes that the received measurement data is the data obtained in the first measurement described in the setting information based on the previously received operation signal and setting information. An index indicating the second measurement item (for example, “stain measurement”) is attached, and the measurement data is stored (S609).

The PC 400 refers to the setting information, and when there is a next measurement item, the PC 400 transmits a mode switching command to the scope camera 300 via the first communication unit 411 (S611). When receiving the switching command, the scope camera 300 notifies the user, and the user who receives this notification recognizes that the switching operation is necessary. When the user switches the mode by operating the switch 370 while viewing the screen of the PC 400 as necessary, an operation signal is transmitted to the PC 400 and the switching is executed in S614 (S615). Then, measurement is executed (S616), and measurement data is transmitted to the PC 400 (S617).
The PC 400 stores the received measurement data with an index indicating that it is the second measurement result described in the setting information (S618).
The PC 400 confirms the setting information, and if there is a next measurement item, transmits a switching command (S619).

In this way, steps S612, S613, S615, S616, S617, S618, and S619 are repeated until the PC 400 determines that all measurement items have been completed.
When the PC 400 determines that all items have been completed (S630), or receives an operation signal instructing the end of measurement input through the switch 370 (S629), one folder is associated with the measurement date and time. For example, the stored series of data is stored in association with each other.

According to the second embodiment, the scope camera 300 and the PC 400 operate in conjunction with each other, and the user only has to operate the scope camera 300 in accordance with the notification. Therefore, various types of measurements can be easily performed. On the other hand, even if a plurality of types of measurement items are included in a series of measurements, the PC 400 reliably determines which type of measurement results the measurement data sent from the scope camera 300 indicates. I can grasp it.

In addition, two communication paths are provided, and control signals with a relatively small amount of data are transmitted by wireless communication, while image data having a relatively large amount of data is transmitted by wired communication, thereby efficiently transferring data. be able to. In addition, since an existing data transfer driver program such as a USB connection can be used for the image data transmission / reception processing portion, a control program for communicating with the scope camera 300 by the PC 400 can be easily created.

The measurement content, type, and number of items using the scope camera 300 described above are merely examples. In short, an imaging apparatus according to the present invention includes an information processing apparatus, an imaging unit capable of switching a plurality of optical systems, an operation unit for switching the optical systems, and a notification unit, and the information processing.
