<p>To reduce power consumption while reducing speckle noise. Disclosed is an image display device, wherein: a waveform-pattern selecting section selects a waveform pattern (PT1) including at least one ON period if the tone-to-be-displayed is lower than a given threshold, and selects a waveform pattern (PT2) in which the ON period is divided more finely than in the waveform pattern (PT1) if the tone-to-be-displayed is higher than or equal to the threshold; and a laser beam source emits a laser beam having an output level corresponding to the tone-to-be-displayed in accordance with the selected waveform pattern (PT1 or PT2).</p> |
