Terminal device
Provided is a terminal device that can easily photograph a measurement subject and measure bioinformation for the measurement subject. A terminal device comprises an information acquisition unit that acquires an image of a measurement subject captured by a photography unit, a slope detection unit that detects the slope of the face of the measurement subject on the screen of a display unit on the basis of a facial image of the measurement subject included in the image captured by the photography unit, and a display control unit that displays a first indicator image that has been matched to the slope of the face detected by the slope detection unit on top of an image displayed at the screen of the display unit that includes the measurement subject.
1 . A terminal device comprising:
a photography unit;
a display unit;
an information acquisition unit configured to acquire an image of a measurement subject photographed by the photography unit as information for measuring biological information of the measurement subject;
a slope detection unit configured to detect a slope of a face of the measurement subject in a screen of the display unit based on a face image of the measurement subject included in the image photographed by the photography unit; and
a display control unit configured to cause a first indicator image to be displayed on top of the image including the measurement subject displayed in the screen of the display unit, the first indicator image corresponding to the slope of the face detected by the slope detection unit.
2 . The terminal device according to claim 1 , wherein the first indicator image is a human-shaped contour guide of a human shape including a face portion and a shoulder portion.
3 . The terminal device according to claim 1 , wherein
the display control unit
displays, before starting measurement, a second indicator image on top of the image, the second indicator image being an indicator by which a measurer adjusts a face position of the measurement subject with a predetermined position in the screen, and
displays, after starting measurement, the first indicator image on top of the image, the first indicator image being a human-shaped contour guide of a human shape including a face portion and a shoulder portion.
4 . The terminal device according to claim 3 , wherein the second indicator image is a frame-shaped guide that encloses the face of the measurement subject displayed in the screen within the frame-shaped guide.
5 . The terminal device according to claim 4 , wherein the frame-shaped guide has an isotropic shape.
6 . The terminal device according to claim 5 , wherein the isotropic shape is one of a circle, a regular polygon, and a sphere.
7 . The terminal device according to claim 1 , wherein the display control unit displays the first indicator image on top of the image at a position to be displayed when there is no displacement in the face position of the measurement subject.
8 . The terminal device according to claim 1 , wherein when the displacement in the face position of the measurement subject is within a predetermined range, the display control unit displays the first indicator image on top of the image following a change in the face position.
9 . The terminal device according to claim 1 , wherein while the first indicator image is displayed, the display control unit disables a function of automatically switching vertical and horizontal display directions of an image with respect to the screen.
10 . The terminal device according to claim 2 , further comprising
an orientation detection unit configured to detect whether the face of the measurement subject turns sideways based on the face image of the measurement subject included in the image photographed by the photography unit, wherein
when the face of the measurement subject turns sideways, the human-shaped contour guide as the first indicator image includes a sideways feature portion.
11 . The terminal device according to claim 2 , further comprising
a size detection unit configured to detect a size of the face of the measurement subject in the screen of the display unit based on the face image of the measurement subject included in the image photographed by the photography unit, wherein
the display control unit
displays, when the size of the face of the measurement subject is equal to or larger than a predetermined threshold, the human-shaped contour guide such that a size of the human-shaped contour guide follows the size of the face of the measurement subject in the image, and
displays, when the size of the face of the measurement subject is smaller than the predetermined threshold, the human-shaped contour guide in a predetermined minimum size.
12 . The terminal device according to claim 1 , further comprising
a situation specification unit configured to specify a situation related to measurement, wherein
the display control unit continues to display the first indicator image when the situation specification unit specifies a measurement failure while the first indicator image is displayed.
13 . The terminal device according to claim 3 , further comprising
a situation specification unit configured to specify a situation related to measurement, wherein
the display control unit stops displaying the first indicator image and displays the second indicator image when the situation specification unit specifies a measurement failure while the first indicator image is displayed.
14 . A non-transitory computer-readable medium coupled to at least one processor and storing one or more computer-executable instructions that, when executed by the at least one processor, cause the at least one processor to function as the terminal device, the information acquisition unit, the slope detection unit, and the display control unit according to claim 1 .
