Classification: CPC G  B | IPC G

Claim 3:
4. A vehicle display control apparatus, comprising:
a line-of-sight detection unit configured to detect a line of sight of a driver;
a visual field estimation unit configured to estimate a visual field of the driver from the detected line of sight; and
a display controller configured to control display information displayed on a display unit of a vehicle based on a positional relationship between the estimated visual field and the display unit, wherein
the visual field estimation unit is configured to
detect a fixation point at which the line of sight of the driver is fixed, and
estimate a visual field angle to a second fixation point with a first fixation point as a center of the line of sight as a range of the visual field of the driver in a case where movement from the first fixation point to the second fixation point is made within Δt seconds and a displacement amount in a vertical direction of the line of sight of the driver with respect to an imaginary line segment connecting the first fixation point and the second fixation point is within Δd m.
