IMAGE PROJECTION APPARATUS, IMAGE PROJECTION METHOD, AND COMPUTER-READABLE STORAGE MEDIUM |
摘要 |
An image projection apparatus includes a light source configured to emit light with a luminance according to electric power; a color wheel configured to sequentially transmit the light through multiple color filters arranged along a circumferential direction; a light modulation element configured to form an image by modulating an intensity of the light transmitted through the color wheel according to an input signal representing input image data; and a selection controller configured to select, out of a first waveform indicating temporal change in electric power supplied to the light source in a first mode and a second waveform indicating temporal change in electric power supplied to the light source in a second mode, the second waveform when a luminance value of the input signal is equal to or less than a first threshold. A brightness of the image in the second mode is lower than that in the first mode. |
