Abstract: A laser light source device includes a semiconductor laser, a current supplying unit to supply a driving current to the semiconductor laser, and a signal generator to generate current intensity data for setting an intensity of the driving current. The signal generator generates, for an input signal corresponding to continuous pixels for a same color, a plurality of sets of the current intensity data indicating current intensities different from each other, and transmits the plurality of sets of the current intensity data to the current supplying unit while sequentially switching the plurality of sets of the current intensity data. The current supplying unit drives the semiconductor laser based on the plurality of different sets of the current intensity data.

Abstract: An image display device includes a light source that emits a light beam, a screen, a scanning section that scans the screen with the light beam, an optical system, a drive section, and a screen drive circuit. The optical system generates a virtual image by using the light beam that has passed through the screen. The drive section moves the screen at least in parallel to a travel direction of the light beam. The screen drive circuit contains a drive signal table that stores an information group for use in generating a drive signal tailored to stop the screen at different stop locations over different stop periods. The screen drive circuit selects first information in the drive signal table which is associated with displaying of an image and supplies the drive section with a first drive signal generated from the first information.

Abstract: An image display device includes a laser light source, a controller, a temperature acquisition unit, and an image forming unit. The laser light source emits a plurality of laser beams including a red laser beam, a green laser beam, and a blue laser beam. The controller controls lighting of the laser light source. The temperature acquisition unit obtains temperature information with respect to the laser light source. The image forming unit creates an image from the plurality of laser beams emitted from the laser light source. The controller varies a light output ratio between the plurality of laser beams, based on the temperature information obtained by the temperature acquisition unit.

Abstract: An image display device includes a light source, a screen, an optical system, a screen driving mechanism unit, a memory unit, and a screen driving circuit unit. An image is formed on the screen by being irradiated with light from the light source. The screen driving mechanism unit moves the screen in an optical axis direction of the light. A smoothed movement profile is obtained by smoothing a movement profile used as a target for moving the screen so as to make a moving speed of the screen vary gently. The memory unit stores screen driving waveform information that has been generated so that the screen follows the smoothed movement profile. The screen driving circuit unit drives the screen driving mechanism unit, based on the screen driving waveform information stored in the memory unit.

Abstract: An image display device includes a light source, a screen, an optical system and a driving unit. The screen is irradiated with light from the light source to form an image. The optical system generates a virtual image with the light from the screen. The driving unit moves the screen in an optical axis direction. The driving unit includes a holder, one or more elastic members and a driving source. The holder holds the screen. The one or more elastic members support the holder so as to enable the holder to reciprocally move in the optical axis direction. The driving source generates force for moving the holder in the optical axis direction.
