Description

[Technical field]

[0001] The present invention relates to an image acquisition device, an image acquisition method, and a recording medium. [Background technology]

[0002] When a facial image of the person is required during a procedure, there are generally standards regarding the facial image, such as not wearing a hat. In relation to the establishment of standards for face images, Patent Document 1 describes an automatic passport photo machine for taking a face photo that meets the face photo requirements stipulated in the application procedure. Before taking a face photo, the automatic passport photo machine notifies the applicant of the content of the requirements for taking the photo, such as "Please take off your hat" or "Please face forward," by image or sound.

[0003] The automatic passport photo machine also judges whether the face image detected from the face photo image satisfies the face image requirements. If the face image requirements are not all met, the automatic passport photo machine notifies the applicant of the unmet face image requirements by image and / or voice, and retakes the face photo image.

[Figure 6] FIG. 1 is a schematic block diagram illustrating a configuration of a computer according to at least one embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] The following describes embodiments of the present invention, but the following embodiments do not limit the scope of the invention. Furthermore, not all of the combinations of features described in the embodiments are necessarily essential to the solution of the invention. In the following, an example will be described in which the embodiment is applied to acquiring a face image for driver's license renewal. However, the scope of application of the embodiment is not limited to this. The following embodiment can be applied to acquiring various face images for which standards have been established.

[0013] 1 is a schematic diagram showing an example of the configuration of a license renewal system according to an embodiment. In the configuration shown in FIG. The license renewal server device 100 and the image acquisition device 200 communicate with each other via a communication network 900 .

[0014] The license renewal system 10 is a system for renewing a driver's license. In the license renewal system 10, a person to be licensed for renewal can carry out part of the license renewal procedure in advance using the image acquisition device 200. "In advance" here refers to before going to a license renewal facility such as a license center to carry out the license renewal procedure. In particular, a person whose license is to be renewed can take a facial image for a license using the image capture device 200. The facial image for a license is a facial image that is used on a license after license renewal.

[0015] The license renewal server device 100 judges whether or not the person to be licensed renewed who has completed the license renewal procedure meets the conditions for license renewal. If it is judged that the conditions are met, the license renewal server device 100 issues a license after the license renewal. If the person to be licensed renewed takes a license photograph using the image acquisition device 200, the license renewal server device 100 acquires a face image for the license from the image acquisition device 200 and issues a license after the license renewal. The license renewal server device 100 may be configured using a computer such as a workstation or a personal computer (PC).

[0016] The image acquisition device 200 is a device used by a person who is to renew his / her license. As described above, a part of the license renewal procedure can be performed in advance using the image acquisition device 200. A user who is to renew his / her license can take a face image for a driver's license using the image acquisition device 200. In addition, the image acquisition device 200 determines whether the captured face image satisfies the standards for a face image for a driver's license. For example, the image acquisition device 200 may determine whether the captured face image satisfies all of the following standards:

[0017] The background is colorless. The subject is facing forward. The person photographed is not wearing a hat. The image has not been edited. There is 3-4 mm of space above the subject's head. The facial expression is expressionless. The size of the face image (the size of the entire image including parts other than the face image) is a predetermined size. For example, the size of the face image is 3 centimeters in height and 2.4 centimeters in width. The size of the face image in the face image is a predetermined size. For example, the height and width of the face image are each within a predetermined range. The subject is not wearing colored contact lenses.

[0018] However, the standards that the image acquisition device 200 judges are not limited to specific ones. Various standards can be the standards that the image acquisition device 200 judges according to the standards required in the procedure for which the face image is to be submitted. For example, the image acquisition device 200 may be configured to judge whether or not the captured face image satisfies only some of the above standards. In this way, the image acquisition device 200 may be configured to judge whether or not at least one of the above standards is satisfied. The image acquisition device 200 selects, from among the acquired face images, face images that are determined to satisfy the standard.

[0019] The image acquisition device 200 may determine whether an already stored facial image, in addition to or instead of the captured facial image, is the facial image of the person whose license is to be renewed and whether it satisfies the standards for a facial image for a driver's license. When there are multiple face images that meet the standards for a face image for a driver's license, the image acquisition device 200 may present the multiple face images to the user and allow the user to select one of the face images. The image acquisition device 200 may be configured to present to the user, for a face image that does not satisfy the conditions for a face image for a driver's license, the reason why the face image does not satisfy the standards for a face image for a driver's license.

[0020] The image acquisition device 200 may be configured using a smartphone carried by a person who is to renew his / her license. For example, the function of the image acquisition device 200 to perform a part of the license renewal procedure in advance may be executed by the smartphone executing an application program for the license renewal advance procedure.

[0021] However, the configuration of the image acquisition device 200 is not limited to a configuration using a smartphone. For example, a lighting camera may be used as the image acquisition device 200. Alternatively, the image acquisition device 200 may be configured by a computer other than a smartphone, such as a tablet terminal or a personal computer owned by the person whose license is to be renewed, equipped with a camera.

[0022] The communication network 900 mediates communication between the license renewal server device 100 and the image acquisition device 200. The communication network 900 is not limited to a specific type of communication network, and can be various types of communication networks depending on the license renewal server device 100 and the image acquisition device 200. For example, when the image acquisition device 200 is configured using a smartphone and connects to the Internet via an access point, the communication network 900 may be configured to include a combination of a wireless communication network using the access point, the Internet, and a LAN (Local Area Network) on the side of the license renewal server device 100 connected to the Internet.

[0023] Fig. 2 is a schematic block diagram showing an example of the functional configuration of image acquisition device 200. In the configuration shown in Fig. 2, image acquisition device 200 includes a communication unit 210, a display unit 220, an operation input unit 230, a camera 240, a storage unit 280, and a control unit 290. Control unit 290 includes an image acquisition unit 291, an image selection unit 292, a notification unit 293, a cropping unit 294, and a processing determination unit 295.

[0024] The communication unit 210 communicates with other devices under the control of the control unit 290. In particular, the communication unit 210 communicates with the license renewal server device 100 via the communication network 900. Display unit 220 includes a display screen such as a liquid crystal panel or an LED (Light Emitting Diode) panel, and displays various images according to the control of control unit 290. For example, display unit 220 displays various messages for the user. Furthermore, when capturing an image with camera 240, display unit 220 may display the captured images continuously output by camera 240 in real time.

[0025] The operation input unit 230 includes an input device such as a touch sensor that is provided on the display screen of the display unit 220 and configures a touch panel, and receives user operations. The camera 240 captures an image by converting incident light into image data, and outputs the captured image as image data. In particular, the camera 240 captures a face image for a driver's license under the control of the image acquisition unit 291, and outputs the captured still image.

[0026] The storage unit 280 stores various data. The storage unit 280 is configured using a storage device included in the image acquisition device 200. The control unit 290 performs various processes by controlling each unit of the image acquisition device 200. The functions of the control unit 290 are performed, for example, by a CPU (Central Processing Unit) included in the image acquisition device 200 reading a program from the storage unit 280 and executing it.

[0027] The image acquisition unit 291 acquires a plurality of face images as face images for a driver's license. The image acquisition unit 291 corresponds to an example of an image acquisition means. The image acquiring unit 291 may acquire a facial image by photographing using the camera 240. Also, in addition to or instead of photographing with the camera 240, the image acquiring unit 291 may acquire a facial image by reading out a facial image already stored in the storage unit 280.

[0028] The image acquisition unit 291 may capture images multiple times with the camera 240 after the notification unit 293 starts notifying the user, ie, the person to be photographed. For example, while the notification unit 293 is issuing a notification encouraging the subject to move his / her face, or after issuing this notification, the camera 240 may take multiple images. This allows the image acquisition unit 291 to acquire facial images of the subject's face in various orientations, and is expected to acquire a facial image facing forward, which is one of the standards for facial images for illumination certificates.

[0029] In addition to or instead of moving the face of the person to be photographed, the notification unit 293 may issue a notification urging the person to move the camera 240, such as by moving the image acquisition device 200. Then, while the notification unit 293 is issuing this notification, or after issuing this notification, the camera 240 may take multiple images. This allows the image acquisition unit 291 to acquire face images of the person to be photographed in various orientations, and is expected to acquire a face image facing forward, which is one of the standards for face images for illumination certificates.

[0030] When the image is captured by the camera 240, the image acquisition unit 291 may display the captured images continuously output by the camera 240 in real time on a portion of the display screen of the display unit 220 that is close to the camera 240. This allows the user, who is the subject of the image, to check whether or not the face image for the driver's license can be appropriately captured by looking at the image without moving his / her line of sight from the camera 240. The image acquisition unit 291 may link the image captured by the camera 240 with meta information such as the date of capture.

[0031] The image selection unit 292 selects, from among the multiple face images acquired by the image acquisition unit 291, a face image that satisfies the standards for a face image for a driver's license. As described above with respect to image acquisition device 200, image selection unit 292 may select a facial image that satisfies at least one of the following facial image standards: the background is colorless, the person being photographed is facing forward, the person being photographed is not wearing a hat, the image has not been edited, there is a predetermined margin above the image of the person being photographed, the person being photographed has a neutral expression, the overall size of the image is a predetermined size, the height and width of the facial image are each within a predetermined range, and the person being photographed is not wearing colored contact lenses. The image selection unit 292 corresponds to an example of an image selection means.

[0032] When there are multiple face images that meet the standards for a face image for a driver's license, the image selection unit 292 may accept the selection of any one of the face images by the user. For example, the image selection unit 292 may control the display unit 220 to display the multiple face images that meet the standards for a face image for a driver's license. Then, in response to a user operation accepted by the operation input unit 230, the image selection unit 292 may select any one of the multiple face images.

[0033] The notification unit 293 issues a notification regarding the photographing. The notification regarding the photographing issued by the notification unit 293 is not limited to a specific type of notification. For example, the notification regarding the photographing issued by the notification unit 293 may be a notification of a condition regarding the photographed person, such as that the photographed person is not wearing a hat. Alternatively, the notification regarding the photographing issued by the notification unit 293 may be a notification regarding an action during photographing, such as moving the face of the photographed person or moving the image acquisition device 200. The notification unit 293 corresponds to an example of a notification means.

[0034] When a user takes a selfie, that is, when the user photographs himself / herself using image acquisition device 200, notification unit 293 notifies the user who is the person being photographed. In the following, a case where the user photographs himself / herself using image acquisition device 200 will be described as an example. However, the person who operates image acquisition device 200 and the person who is being photographed may be different. The person who operates image acquisition device 200 is also referred to as the photographer.

[0035] The method of notification performed by the notification unit 293 is not limited to a specific method. For example, the notification unit 293 may cause the display unit 220 to display a message. Alternatively, the notification unit 293 may cause a speaker included in the image acquisition device 200 to output a message by voice in addition to or instead of displaying a message by the display unit 220.

[0036] In particular, the notification unit 293 issues a notification regarding the photographing when a face image for a driver's license is photographed. As described above, the notification unit 293 may issue a notification to prompt the user to move the face. For example, the notification unit 293 may issue a notification to prompt the user to move the face left and right. Alternatively, the notification unit 293 may issue a notification to prompt the user to move the face up and down and left and right.

[0037] Alternatively, the notification unit 293 may issue a notification to prompt the user to turn his / her face in a predetermined direction in a predetermined order. For example, the notification unit 293 may switch the direction of an arrow at predetermined time intervals and display the arrow on the display unit 220. Then, the notification unit 293 may prompt the user to move his / her face in the direction of the arrow at the timing when the arrow is displayed. However, the notification performed by the notification unit 293 to prompt the user to move his / her face is not limited to these.

[0038] As described above, in addition to or instead of moving the user's face, the notification unit 293 may provide a notification encouraging the user to move the camera 240, such as by moving the image capture device 200. As described above with respect to the image acquisition device 200, the image acquisition unit 291 may be configured to present to the user the reason why a face image that does not satisfy the conditions for a face image for a driver's license does not satisfy the standards for a face image for a driver's license.

[0039] The cut-out unit 294 cuts out a partial image conforming to the standard of a face image for a driver's license from the face image acquired by the image acquisition unit 291. The cut-out unit 294 corresponds to an example of a cut-out means. For example, the cropping unit 294 enlarges or reduces the face image, and rotates it to correct the inclination. The cropping unit 294 then crops out a partial image that is 3 centimeters long and 2.4 centimeters wide, which is the size of a face image for a driver's license. The cropping unit 294 performs the above-mentioned enlargement or reduction, rotation, and cropping of the partial image so that the resulting image meets the standards for face images for a driver's license, such as the size of the shoulder width and the margin above the head of the image of the person being photographed. The cropping unit 294 may perform correction so as to make the background of the face image colorless.

[0040] The processing determination unit 295 determines whether or not an image has been processed. In particular, when the image acquisition unit 291 acquires a face image that is already stored in the storage unit 280, the processing determination unit 295 determines whether or not this face image has been processed. The camera 240 may take a facial image of the user, and the processing determination unit 295 may compare the captured facial image with a facial image acquired by the image acquisition unit 291 from the storage unit 280. For example, the processing determination unit 295 may compare the relative sizes and positional relationships of each part of the face, such as the eyes, nose, and mouth. This is expected to make it possible to detect processing, such as morphing, in particular. In addition to or instead of the above comparison, the modification determination section 295 may determine whether the brightness of the image is brighter than a predetermined threshold value and whether there are discontinuous parts in the facial contour.

[0041] FIG. 3 is a flowchart showing an example of a processing procedure for the image capture device 200 to capture a face image that satisfies a standard. In the process of Fig. 3, the notification unit 293 issues a notification regarding taking a face image for a driver's license face image (step S101). As described above, the notification unit 293 may issue a notification to prompt the user to move his / her face. In addition to or instead of prompting the user to move his / her face, the notification unit 293 may issue a notification to prompt the user to move the camera 240, such as by moving the image acquisition device 200.

[0042] Next, camera 240 captures images multiple times under the control of image acquisition unit 291 (S102). Image acquisition unit 291 may refer to the images captured by camera 240 to determine whether the user is moving his or her face, and may cause camera 240 to continue capturing images while the user is moving his or her face. The image acquisition unit 291 may acquire a face image stored in the storage unit 280 in addition to or instead of the image captured by the camera 240 .

[0043] Next, the cutout unit 294 cuts out a partial image from each of the images obtained in step S102 (step S103). As described above, the cutout unit 294 enlarges, reduces, and rotates the image in accordance with the standards for facial images for a driver's license, and cuts out a facial image of a size defined by the standards for facial images for a driver's license. If a partial image that meets the standards cannot be obtained, the cutout unit 294 may output information indicating that the cutout has failed instead of a partial image.

[0044] Next, the processing determination unit 295 determines whether or not each of the partial images (face images) cut out by the cut-out unit 294 has been processed (step S104). Then, the image selection unit 292 selects a face image that satisfies the standard of a face image for a driver's license from among the face images determined to be unedited (step S105). When there are a plurality of face images that are determined to satisfy the standard of a face image for a driver's license, the image selection unit 292 may select any one of the plurality of face images based on a user's selection. After step S105, the image acquisition device 200 ends the process of FIG.

[0045] As described above, the image acquisition unit 291 acquires a plurality of face images. The image selection unit 292 selects, from the plurality of face images, a face image that satisfies the standard of a face image for a driver's license, which is a standard stipulated according to the intended use of the face image. In this way, by having the image acquisition unit 291 acquire a plurality of face images, it is expected that the time required to acquire a face image that satisfies the standard will be short.

[0046] In particular, compared to a method of acquiring one facial image and then acquiring a further facial image if the acquired facial image is determined not to satisfy the standards, image acquisition device 200 is expected to take less time because it does not repeatedly switch between determining whether the standards are satisfied and acquiring the image.

[0047] Furthermore, the notification unit 293 issues a notification regarding the image capture. After the notification unit 293 starts the notification, the image acquisition unit 291 captures images multiple times with the camera 240. If the photographer or the photographed person, or both, follow the notification from notification unit 293, the likelihood of obtaining a face image that meets the standards for a driver's license face image increases.

[0048] Furthermore, the notification unit 293 issues a notification urging the subject to move his or her face. This enables the image acquisition unit 291 to acquire facial images of the subject's face in various orientations, and is expected to enable acquisition of a facial image facing forward, which is one of the standards for facial images for illumination certificates.

[0049] Moreover, while the notification unit 293 is issuing a notification urging the subject to move his / her face, the image acquisition unit 291 captures the image multiple times with the camera 240. This allows the image acquisition unit 291 to capture the image at the timing when the subject is moving his / her face, and it is expected that facial images of the subject's face in various orientations can be acquired as described above.

[0050] Furthermore, the notification unit 293 issues a notification urging the user to move the camera 240. This enables the image acquisition unit 291 to acquire facial images of the subject's face in various orientations, and is expected to enable acquisition of a facial image facing forward, which is one of the standards for facial images for illumination certificates.

[0051] Moreover, the image acquiring unit 291 captures images multiple times with the camera 240 while the notification unit 293 is issuing the notification urging the user to move the camera 240. This allows the image acquiring unit 291 to capture images at the timing when the photographer is moving the camera, and it is expected that facial images of the subject's face in various orientations can be acquired as described above.

[0052] Furthermore, the notification unit 293 notifies the photographed person. In the image acquisition device 200, even when the user is the person being photographed, i.e., when the user photographs himself, the person being photographed will be more likely to obtain a facial image that meets the standards for a driver's license facial image by following the notification from the notification unit 293.

[0053] Moreover, the cutout unit 294 cuts out a partial image from the face image in accordance with the standard. As a result, the image acquisition device 200 can obtain a face image having a size that complies with the standard of the face image for illumination proof.

[0054] 4 is a diagram showing an example of the configuration of an image acquisition device according to an embodiment. In the configuration shown in FIG. In this configuration, the image acquisition unit 611 acquires a plurality of face images. The image selection unit 612 selects a face image that satisfies a standard defined according to the intended use of the face image from the plurality of face images acquired by the image acquisition unit 611. The image acquisition unit 611 corresponds to an example of an image acquisition means, and the image selection unit 612 corresponds to an example of an image selection means.

[0055] In this way, by having the image acquisition unit 611 acquire a plurality of face images, it is expected that the time required to acquire a face image that satisfies the standard will be short. In particular, compared to a method in which one facial image is acquired and then another facial image is acquired if the acquired facial image is determined not to meet the standards, image acquisition device 610 is expected to take less time because it does not repeatedly switch between determining whether the standards are met and acquiring an image.

[0056] 5 is a flowchart showing an example of a process procedure of an image acquiring method according to the embodiment. The image acquiring method shown in FIG 5 includes acquiring an image (step S611) and selecting an image (step S612).

[0057] In acquiring an image (step S611), a plurality of face images are acquired. In selecting an image (step S612), a face image that satisfies a standard defined according to a purpose of use of the face image is selected from the plurality of face images acquired in step S611.

[0058] By acquiring a plurality of face images in this manner, it is expected that the time required to obtain a face image that satisfies the standard will be shortened. In particular, compared to a method in which one facial image is acquired and, if the acquired facial image is determined to not satisfy the standards, a further facial image is acquired, the method described in FIG. 5 is expected to take less time because it does not require repeated switching between determining whether the standard is satisfied and acquiring an image.

[0059] FIG. 6 is a schematic block diagram illustrating a configuration of a computer according to at least one embodiment. In the configuration shown in FIG. 6, a computer 700 includes a CPU 710, a main memory device 720, an auxiliary memory device 730, and an interface 740.

[0060] Any one or more of the image acquisition device 200 and the image acquisition device 610 may be implemented in the computer 700. In this case, the operation of each of the above-mentioned processing units is stored in the auxiliary storage device 730 in the form of a program. The CPU 710 reads the program from the auxiliary storage device 730, loads it in the main storage device 720, and executes the above-mentioned processing according to the program. The CPU 710 also secures a storage area in the main storage device 720 corresponding to each of the above-mentioned storage units according to the program. Communication between each device and other devices is executed by the interface 740 having a communication function and performing communication according to the control of the CPU 710.

[0061] When the image acquisition device 200 is implemented in the computer 700, the operations of the control unit 290 and each of its units are stored in the form of a program in the auxiliary storage device 730. The CPU 710 reads the program from the auxiliary storage device 730, loads it into the main storage device 720, and executes the above-mentioned processing in accordance with the program. Furthermore, the CPU 710 reserves a storage area corresponding to the storage unit 280 in the main storage device 720 in accordance with the program.

[0062] Communication by communication unit 210 is performed by interface 740 having a communication device and operating under the control of CPU 710. Display by display unit 220 is performed by interface 740 having a display device and displaying various images under the control of CPU 710. Reception of user operations by operation input unit 230 is performed by interface 740 having an input device and outputting information indicating the received user operations to CPU 710. Shooting by camera 240 is performed by interface 740 having a camera and performing shooting under the control of CPU 710.

[0063] When the image acquisition device 610 is implemented in the computer 700, the operations of the image acquisition unit 611 and the image selection unit 612 are stored in the form of a program in the auxiliary storage device 730. The CPU 710 reads the program from the auxiliary storage device 730, loads it in the main storage device 720, and executes the above-mentioned processing in accordance with the program. Furthermore, the CPU 710 allocates a storage area in the main storage device 720 for the image acquisition device 610 to perform processing in accordance with the program.

[0064] Communication by the image acquisition device 610 is performed by the interface 740 having a communication device and operating under the control of the CPU 710. Display by the image acquisition device 610 is performed by the interface 740 having a display device and displaying various images under the control of the CPU 710. Reception of a user operation by the image acquisition device 610 is performed by the interface 740 having an input device and outputting information indicating the received user operation to the CPU 710. Photography by the image acquisition device 610 is performed by the interface 740 having a camera and performing photography under the control of the CPU 710.

[0065] Note that a program for executing all or part of the processing performed by image acquisition device 200 and image acquisition device 610 may be recorded on a computer-readable recording medium, and the program recorded on the recording medium may be read into a computer system and executed to perform processing of each part.
