Abstract: A projection apparatus includes a light source assembly, a display control circuit, a light valve, a vibrating lens drive assembly, and a vibrating lens. The display control circuit is configured to obtain a plurality of sub-images; in a process of emitting beams of three primary colors by the light source assembly to the light valve sequentially, control, according to primary color parameters of the pixels in each sub-image, the light valve to sequentially reflect beams corresponding to the plurality of sub-images to the vibrating lens; and in a process of projecting each sub-image, transmit a vibrating lens current control signal corresponding to the sub-image to the vibrating lens drive assembly. The vibrating lens drive assembly is configured to provide at least one vibrating lens driving current to the vibrating lens according to the vibrating lens current control signal corresponding to the sub-image.
