Abstract: A head-up display (HUD) including a direction-information generator, a shift device, and a display system. The direction-information generator generates direction information to be superimposed on a road surface ahead of a vehicle on which the HUD is mounted. The direction information represents a direction of travel to be followed by the vehicle. The shift device shifts at least some of the direction-change information into the display area when the direction information includes direction-change information to represent a change in the direction of travel and the direction-change information falls outside a display area. The display system displays the direction information within the display area as a virtual image.

Abstract: F-theta lenses, included in scanning lens systems, are arranged on a main scanning plane facing an optical deflector and substantially linearly symmetrically on the main scanning plane with reference to a rotational center of the optical deflector. Each f-theta lens has a no-power portion in the main scanning direction. Synchronization-detecting light passes through the no-power portion of the f-theta lens, thus enabling reduction in color shift due to temperature variation in an image forming apparatus without increasing the cost and complexity in controlling color shift.
