This invention discloses an image capture device for fundus and an imaging method thereof. The image capture device includes a lighting module, a splitter, a monochrome image sensor and an image synthesis module. The lighting module emits plurality beams of monochromatic light. The splitter is disposed on a light path of the lighting module. The splitter reflects the plurality beams of the monochromatic light to a fundus of an examinee and forms a plurality of reflecting light respectively through reflection of the fundus. The monochrome image sensor receives the plurality beams of the reflecting light and produces a monochromatic image corresponding to each beam of the monochromatic light. The image synthesis module receives each of the monochromatic images and synthesizes each monochromatic image into a color image. By such arrangements, the invention provides good quality fundus imaging and reduces costs.
