Abstract: A control device includes an acquirer, a timing detector, a controller, and a driver. The acquirer acquires an output voltage from a light detector for receiving laser light scanned by a light source and a deflector. The timing detector detects reference timings of the laser light on forward and backward paths in a scanning direction based on the output voltage. The controller generates a control signal for causing the light source and the deflector to draw a forward path image on a scanned surface from time obtained by adding a time to the reference timing on the forward path and to draw a backward path image on the surface from time obtained by adding a time to the reference timing on the backward path. The driver draws the images by driving the deflector, based on the control signal.

Abstract: A control device (10) includes an acquirer (32), a timing detector (33), a controller (30), and a driver (31). The acquirer (32) is configured to acquire an output voltage from a light detector (16) for receiving laser light scanned by a light source (12) and a deflector (13). The timing detector (33) is configured to detect reference timings of the laser light on forward and backward paths in a scanning direction based on the output voltage. The controller (30) is configured to generate a control signal for causing the light source (12) and the deflector (13) to draw a forward path image on a scanned surface from time obtained by adding a time to the reference timing on the forward path and to draw a backward path image on the surface from time obtained by adding a time to the reference timing on the backward path. The driver (31) is configured to draw the images by driving the deflector (13), based on the control signal.

Abstract: A display apparatus includes: a light source to emit light; a dimming unit including a plurality of regions having transmittances that are mutually different from one another; a switching unit to switch a region of the dimming unit through which the light passes, between the plurality of regions of the dimming unit; a scanning unit to scan a scan area at a predetermined frame rate with the light, the scan area having a first area in which an image is formed and a second area different from the first area; a sensor to detect a light amount of the light emitted to the second area; and a controller to determine a boundary timing at which the light has passed through a boundary portion between two adjacent regions of the dimming unit based on characteristics of a temporal change in the detected light amount.
