3 . The display control apparatus according to claim 1 , wherein
based on a number of times the line of sight is directed to the display apparatus selected by the first selector, the second selector selects, as the display apparatus for displaying the information, the display apparatus to which the line of sight of the occupant is more likely to be directed.
4 . The display control apparatus according to claim 1 , wherein
the second selector selects, as the display apparatus for displaying the information, one of a plurality of the display apparatuses selected by the first selector, the one display apparatus being a display apparatus to which the line of sight has been directed at latest time.
5 . The display control apparatus according to claim 1 , wherein
based on cumulative time when the information is displayed on the display apparatus selected by the first selector, the second selector selects the display apparatus for displaying the information.
6 . The display control apparatus according to claim 1 , wherein
based on a number of times the information is displayed on the display apparatus selected by the first selector, the second selector selects the display apparatus for displaying the information.
7 . The display control apparatus according to claim 1 , wherein
the second selector selects, as the display apparatus for displaying the information, one of a plurality of the display apparatuses selected by the first selector, the one display apparatus being a display apparatus on which an alert image has been displayed at latest time.
8 . The display control apparatus according to claim 1 , wherein
the second selector selects a preset display apparatus as the display apparatus to which the line of sight of the occupant is more likely to be directed than to the other display apparatuses.
9 . The display control apparatus according to claim 1 , further comprising:
an image information output that
when the second selector selects the display apparatus to which the line of sight of the occupant is more likely to be directed than to the other display apparatuses, generates image information prompting a shift of the line of sight from a first display apparatus to a second display apparatus, the first display apparatus being one of the plurality of display apparatuses which is not selected by the second selector, the second display apparatus being one of the plurality of display apparatuses which is selected by the second selector, and
outputs the image information to the first display apparatus.
10 . The display control apparatus according to claim 1 , wherein
the second selector selects a terminal apparatus as the display apparatus to which the line of sight of the occupant is more likely to be directed than to the other display apparatuses, the terminal apparatus being portable by the occupant.
11 . The display control apparatus according to claim 1 , wherein
an alert image for notifying the occupant of existence of an object detected by a detection apparatus for detecting an object existing in a surrounding area of the vehicle is displayed.
12 . The display control apparatus according to claim 11 , wherein
when an operation corresponding to the alert image is completed, the alert image is deleted.
13 . The display control apparatus according to claim 1 , wherein
the plurality of display apparatuses are a center display, an in-vehicle meter panel, and a head-up display.
14 . The display control apparatus according to claim 1 , wherein
the display apparatus for displaying the information displays an image in which an alert image is superimposed on an original image.
15 . The display control apparatus according to claim 1 , wherein
when the line-of-sight information is not outputted, a notification is given to a driver.
16 . The display control apparatus according to claim 15 , wherein
the notification is a voice, blinking of a lamp inside the vehicle, or a vibration of steering or a seat.
17 . The display control apparatus according to claim 1 , wherein
the first selector identifies a display apparatus existing at a position closest to the line of sight as a display apparatus existing in a direction in which the line of sight of a driver is directed.
18 . A display control system, comprising:
a display control apparatus according to claim 1 ; and
a plurality of the display apparatuses.
19 . A vehicle in which a display control system according to claim 11 is mounted.
20 . A display control method, comprising:
a detecting step of detecting a line of sight of an occupant of a vehicle by using an imager;
a line-of-sight information outputting step of outputting line-of-sight information indicating a direction in which the line of sight is directed;
a first selecting step of selecting one of a plurality of display apparatuses as a display apparatus for displaying information provided to the occupant of the vehicle, when the line-of-sight information is outputted, the plurality of display apparatuses being configured to display the information, the one display apparatus existing in the direction in which the line of sight is directed; and
a second selecting step of selecting, as the display apparatus for displaying the information, one of the plurality of display apparatuses to which the line of sight of the occupant is more likely to be directed than to other display apparatuses, when the line-of-sight information is not outputted.
