摘要： The present invention provides a disc device capable of normally reproducing recorded information on a disc type recording medium while complementing the recorded information in a damaged portion of the recording medium with complementary information, and capable of constantly holding useful complementary information. The complementary information for complementing the recorded information in the damaged portion of the optical disc is acquired from a server and saved in a storage area of a storing unit, and the recorded information on the optical disc is reproduced while complementing the recorded information in the damaged portion with the complementary information. When a capacity of a free space in the storage area is less than a capacity necessary for saving acquired new complementary information, usefulness of the complementary information is evaluated based on time elapsed from last referenced time, a reference count, and an acquisition required expense for the complementary information saved in the storage area, the complementary information is deleted from the storage area in order of lower usefulness to enlarge the free space, and the new complementary information is saved in the free space.

摘要： Provided is an image display device which carries out bi-directional line sequence scanning, and which appropriately corrects positioning misalignment of projection spots while efficaciously minimizing speckle noise. A laser controller unit sets waveform patterns when scanning in the forward direction, reflecting waveform patterns (GPT, BPT) about the time axis. The laser controller unit further sets waveform patterns when scanning in the reverse direction, reflecting the waveform patterns when scanning in the forward direction about the time axis. Waveform patterns (RPT, GPT, BPT) comprise drive start timings and drive end timings of laser sources within a pixel display period. The off period from the start timing of the pixel display period to the drive start timing and the off period from the drive end timing to the end timing of the pixel display period are set to be asymmetrical about the time axis.

摘要： An image display apparatus wherein reduction in contrast or resolution is prevented is provided. A laser projector as an embodiment of the image display apparatus includes a memory storing a threshold value predetermined for changing a driving mode of a laser light source, a calculator for calculating an optical power level for projecting an image, a driving-mode selector selecting a mode for driving the laser light source, a driving controller for sending a signal to the laser light source in accordance with a selected driving mode, and a laser emitter. The laser projector operates at least at a bias current value Ib or more. In this case, when the optical power level is lower than or equal to a predetermined threshold value TH, the laser projector emits pulsed light. When the optical power level based on a video signal exceeds threshold value TH, the laser projector changes the driving mode of laser light emission from pulsed light emission to DC light emission, to supply a current higher than or equal to bias current value Ib to each laser light source.

摘要： An image display apparatus is provided that allows a user to check image content even in a place where there is no projection screen. A projector that is one mode of the image display apparatus includes a casing, a projection aperture provided in the casing, and an internal projection mirror and a built-in screen that are provided in a casing. When the projector is being folded, laser light emitted from the projection aperture is reflected by the internal projection mirror. The reflected light is projected onto the built-in screen, whereby an image is displayed.
