Abstract
A projection apparatus and its operation method are provided. The projection apparatus includes a light-emitting device, a driving circuit coupled to the light-emitting device, and a control circuit receiving at least one video frame and analyzing color content of the at least one video frame. According to at least one control signal, the driving circuit drives the light-emitting device to generate a projected beam. The control circuit selects a highlight mode or a normal mode as a selected mode according to the color content and correspondingly sets at least one control signal to the driving circuit according to the selected mode. A brightness of the projected beam of the light-emitting device in the highlight mode is greater than that in the normal mode.
