摘要: A scanning image display includes a light source, a light detector, a scanning section, a storage section, a current controlling section, a reference current section, a sweep section, and a change section. The light detector detects the laser light emitted from the light source. The scanning section scans the laser light. The current controlling section controls laser light by supplying a current supplied to the light source. The storage section is configured to store a reference current value, a reference light output value, and a gamma table. The reference current section supplies the reference current value to the current controlling section. The sweep section sweeps current values supplied to the current controlling section to obtain one current value where the detected laser light corresponds to the reference light output value. The change section changes the gamma table based on the one current value obtained by the sweep section.
