A display control apparatus includes a display control section, a space information acquisition section, and a reporting section. The display control section generates a virtual space image by specifying a viewpoint position and a direction of line of sight and displays the image on a head-mounted display. The space information acquisition section acquires information related to a position of an object existing in a space around a user wearing the head-mounted display. The reporting section informs the user that the object exists around the user when a distance between the head-mounted display and the object becomes smaller than a given value.

An image projection device includes: a projection unit that irradiates a pupil 40 of an eyeball 36 of a user with an image light beam 34a forming an image to project the image onto a retina 38 of the eyeball; a detection unit that detects a direction 52 in which the pupil has moved relative to a face of the user; and a control unit that controls the projection unit based on a detected direction in which the pupil has moved so that the pupil is irradiated with the image light beam and the image is moved in a direction opposite to the direction in which the pupil has moved with respect to a position on which the image has been projected before a move of the pupil in a coordinate system visually recognized by the user.

Provided is a head-up display device with which it is possible to display an image easily recognized by a user. A display for a display mechanism in the head-up display device includes: a light source unit capable of generating light that is the origin of a scanning line; a scan unit for scanning light in a first direction and in a second direction using a first scan element and a second scan element, respectively; a processing unit for generating a first drive signal having a frequency that matches the resonance frequency of the first scan element; and a drive unit for executing a resonance mode that is based on the first drive signal. The processing unit generates a second drive signal having a variable display waveform that is dependent on the resonance frequency, fixed first non-display waveforms that are not dependent on the resonance frequency, and a variable second non-display waveform that is dependent on the resonance frequency. The drive unit drives the second scan element in a non-resonance mode that is based on the second drive signal.
