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： The image display device resolves inconsistency in the brightness of the image while effectively reducing local speckle noise that remains due to the laser scanning of which the scanning speed fluctuates. A waveform pattern (PT2) that includes an on period and an off period within the pixel displaying period (T2) is selected for the center pixel (P512). A waveform pattern (PT1) that includes an on period and an off period within the pixel displaying period (T1) that is longer than the pixel displaying period (T2) is selected for the side pixel (P1) or (P1023) that is scanned at a scanning speed slower than that for the center pixel (P512). Here, the on period in the waveform pattern (PT1) is segmented more than the on period in the waveform pattern (PT1), and the time ratio of the on period accounting for the waveform pattern (PT1) is smaller than the time ratio of the on period accounting for the waveform pattern (PT2).

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.
