Imaging state confirmation device
An imaging state confirmation device for confirming an imaging state by an imaging device that images an image of a driver includes a position detection unit that detects a position of a facial image of the driver in an image imaged by the imaging device at an arbitrary point in time, an icon display unit that displays an icon in an arbitrary frame of the display device so as to correspond to a position of a facial image in the image, and a positional change display unit that changes a position of an icon in the frame of the display device and displays the icon based on an adjustment amount of a state of a seat on which the driver is seated or an adjustment amount of a state of the imaging device.
1 . An imaging state confirmation device comprising a processor configured to:
acquire a first image of a driver that is captured by an imaging device; and
execute an adjustment process according to a state of a first facial image of the driver within the first image, the adjustment process including
acquiring a second image of the driver that is captured by the imaging device,
detecting a position of a second facial image of the driver within the second image,
displaying, on a display device, the second image and an icon within a predetermined frame, the icon being positioned to indicate the detected position of the second facial image,
determining whether at least one of the imaging device or a seat in which the driver is seated has been moved,
acquiring a movement amount of the imaging device, the seat, or both of the imaging device and the seat, in response to a determination that at least one of the imaging device or the seat has been moved,
determining an updated position of the icon within the predetermined frame based on the acquired movement amount, and
moving the icon displayed on the display device to the determined updated position.
2 . The imaging state confirmation device according to claim 1 , wherein
the adjustment process further includes
calculating a deviation amount from an appropriate position or an appropriate range of the position of the second facial image of the driver, and
correcting the deviation amount based on the acquired movement amount,
the icon is positioned based on the deviation amount, and
the updated position is determined based on the corrected deviation amount.
3 . The imaging state confirmation device according to claim 1 , wherein the processor is further configured to output notification regarding a seating posture based the state of the first facial image.
4 . The imaging state confirmation device according to claim 1 , wherein
the processor is further configured to determine whether the first facial image of the driver satisfies a predetermined criterion, and
the adjustment process is executed in a case where a determination that the first facial image of the driver does not satisfy the predetermined criterion.
5 . The imaging state confirmation device according to claim 2 , wherein the adjustment process further includes
determining whether the corrected deviation amount is equal to or less than a predetermined reference value, and
outputting a message notifying that a face of the driver is at the appropriate position or within the appropriate range, in response to a determination that the corrected deviation amount is equal to or less than the predetermined reference value.
6 . The imaging state confirmation device according to claim 3 , wherein
the processor is further configured to receive an authorization to start the adjustment process from the driver after outputting the notification, and
the adjustment process is executed in response to the authorization.
7 . The imaging state confirmation device according to claim 3 , wherein the notification includes a warning and a message, the warning notifying the driver that a face of the driver is not recognized, and the message requiring that the driver take the seating posture for driving.
8 . The imaging state confirmation device according to claim 7 , wherein
the processor is further configured to determine whether the first facial image of the driver satisfies a predetermined criterion,
the warning is output in response to a determination that the first facial image of the driver does not satisfy the predetermined criterion,
the message is output after or simultaneously with outputting the warning, and
the adjustment process is executed after outputting the warning.
9 . The imaging state confirmation device according to claim 8 , wherein
the processor is further configured to receive an authorization to start the adjustment process from the driver after outputting the warning, and
the adjustment process is executed in response to the authorization.
10 . The imaging state confirmation device according to claim 1 , wherein the adjustment process further includes notifying the driver of a timing for capturing the second image by displaying a countdown on the display device.
11 . The imaging state confirmation device according to claim 1 , wherein the icon has a shape corresponding to an outline of the second facial image of the driver.
