Projection-type image displaying apparatus

A projection-type image display apparatus for displaying an image on a projected plane, comprising:

• a plurality of laser light sources each configured to emit a laser light;
• a light-path combining element configured to combine light paths of the laser lights each emitted from the plurality of laser light sources;
• a light path splitting element configured to split the combined light path into first and second light paths, each of the laser lights being split into a first light passing the first light path and a second light passing the second light path;
• a scanning mirror configured to reflect the first lights of the laser lights to scan the projected plane with the first lights of the laser lights;
• a light receiving element configured to receive the second lights of the laser lights to detect light amounts of the received second lights;
• and
• a control circuit configured to control the scanning mirror to scan an image forming area of the projected plane with the first lights of the laser lights based on image data and control the plurality of laser light sources so as to reproduce a color based on the image data,
• wherein the control circuit is configured to
• control the light receiving element to detect the light amounts of the plurality of laser light sources when the image forming area is scanned with the first light, and
• adjust emitting light amounts of the plurality of laser light sources based on the detected light amounts of the plurality of laser light sources.
