Abstract:
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).
