Display control apparatus, display control method, and computer-readable storage medium storing program
A display control apparatus comprises: a detection unit configured to analyze a line of sight of a driver of a vehicle, and detect a viewpoint of the driver in a visual field region of the driver that is obtained as a result of the analysis; a display control unit configured to display an image such that the image is superimposed on the visual field region, based on a result of the detection by the detection unit; and a transmission control unit configured to, if a condition is satisfied, transmit related information that is related to information represented by the image to an external terminal, in addition to or instead of the display control unit displaying the image.
1. A display control apparatus comprising:
at least one processor circuit with a memory comprising instructions, that when executed by the processor circuit, cause the at least one processor circuit to at least:
analyze a line of sight of a driver of a vehicle, and detect a viewpoint of the driver in a visual field region of the driver that is obtained as a result of the analysis;
display an image such that the image is superimposed on the visual field region, based on the result of the analysis and the viewpoint detected; and
in accordance with a time period for which the line of sight of the driver analyzed is stationary, control transmission of related information that is related to information represented by the image to an external terminal, in addition to or instead of displaying the image
wherein, if the time period reaches a first predetermined time period, the related information is transmitted to the external terminal in addition to displaying the image.
2. The display control apparatus according to claim 1 ,
wherein, if the time period does not reach a second predetermined time period, the related information is transmitted to the external terminal instead of displaying the image.
3. The display control apparatus according to claim 2 ,
wherein if the time period reaches the second predetermined time period, the image is displayed, and the related information is not transmitted to the external terminal.
4. The display control apparatus according to claim 2 ,
wherein the time period reaches a third predetermined time period that is shorter than the second predetermined time period.
5. The display control apparatus according to claim 2 ,
wherein, when executed, the instructions further causes the processor circuit to
at least:
determine whether or not a specific event has occurred if the time period does not reach the second predetermined time period,
wherein if it is determined that the specific event has occurred, the related information is transmitted to the external terminal, instead of the image being displayed.
6. The display control apparatus according to claim 5 ,
wherein if it is determined that the specific event has not occurred, the related information is not transmitted to the external terminal.
7. The display control apparatus according to claim 1 , wherein, when executed, the instructions further causes the processor circuit to at least:
decide whether or not the image has been checked by the driver, after the image was displayed,
wherein, if the image has not been checked by the driver, the related information is transmitted to the external terminal.
8. The display control apparatus according to claim 7 ,
wherein if the image has been checked by the driver, the related information is not transmitted to the external terminal.
9. The display control apparatus according to claim 7 ,
wherein deciding whether or not the image has been checked by the driver is based on whether or not the time period reaches a fourth predetermined time.
10. The display control apparatus according to claim 1 ,
wherein the external terminal is a mobile terminal held by the driver.
11. A display control method to be executed by a display control apparatus, the method comprising:
analyzing a line of sight of a driver of a vehicle, and detecting a viewpoint of the driver in a visual field region of the driver that is obtained as a result of the analysis;
displaying an image such that the image is superimposed on the visual field region, based on a detection result; and
in accordance with a time period for which the line of sight of the driver analyzed is stationary, transmitting related information that is related to information represented by the image to an external terminal, in addition to or instead of displaying the image,
wherein, if the time period reaches a first predetermined time period, the related information is transmitted to the external terminal in addition to displaying the image.
12. A non-transitory computer-readable storage medium storing a program for causing a computer to perform functions of:
analyzing a line of sight of a driver of a vehicle, and detecting a viewpoint of the driver in a visual field region of the driver that is obtained as a result of the analysis;
displaying an image such that the image is superimposed on the visual field region, based on a detection result; and
in accordance with a time period for which the line of sight of the driver analyzed is stationary, transmitting related information that is related to information represented by the image to an external terminal, in addition to or instead of displaying the image,
wherein, if the time period reaches a first predetermined time period, the related information is transmitted to the external terminal in addition to displaying the image.
