The present application provides an image acquisition apparatus and method. The image acquisition apparatus comprises a filter, an image sensor, a control unit, and an image synthesis unit. In embodiments of the present application, the image sensor performs photoelectric imaging on the visible light passing through the filter in a first image sampling interval to obtain a first image comprising chromaticity information, and performs photoelectric imaging on the infrared light (or the infrared light and the visible light) passing through the filter in a second image sampling interval to obtain a second image comprising the chromaticity information, and then the image synthesis unit synthesizes the first image with the second image to obtain a target image of higher quality, so that there is no need to use a beam splitting prism, and only one sensor is needed, which can reduce material costs and the complexity of the apparatus.
