A vascular imaging apparatus and a vascular imaging method are disclosed. The vascular imaging apparatus (10) includes: a light source device (100), an image acquisition device (110), a projection device (130) and an image processor (120). The light source device (100) is configured to emit visible light and infrared light to a body portion to be tested (200) in a time-sharing manner； the image acquisition device (110) is configured to receive the visible light and the infrared light reflected by the body portion to be tested (200) to acquire a visible image and an infrared image respectively； the image processor (120) is configured to perform image processing on the infrared image and the visible image, to acquire a vascular enhancement image of the body portion to be tested (200)； the projection device (130) is configured to project the vascular enhancement image onto the body portion to be tested (200). The vascular imaging apparatus (10) can eliminate background light of a non-vascular region by performing image processing on the infrared image and the visible image, so as to enhance contrast between a vascular region and the non-vascular region and improve the recognizability of the blood vessel.
