A venous positioning projector includes an infrared light source module, a light splitting element, an infrared light image capture module, a processor, and a visible light projection module. The infrared light source module outputs a first infrared light to a target surface. The infrared light image capture module includes a filter and an infrared light image capture element. The light splitting element transmits a second infrared light reflected by the target surface to the filter. The infrared light image capture element receives the second infrared light passing through the filter. The processor generates venous image data according to the first infrared light and the second infrared light received by the infrared light image capture element. The visible light projection module generates a visible light based on the venous image data. The visible light is transmitted to the target surface through the light splitting element to generate a venous image.

An endoscope stereo imaging device includes an endoscope lens assembly and an imaging module. The imaging module includes first, second and third lens assemblies, a beam splitter, first and second image sensors and a micro lens array. A light beam from the endoscope lens assembly is transmitted to the beam splitter after passing through the first lens assembly and is split into first and second portions of the light beam. The first portion light beam is transmitted to the first image sensor via the second lens assembly and forms a two-dimensional image. The second portion light beam is transmitted to the second image sensor via the third lens assembly and the micro lens array sequentially and forms a first three-dimensional image.

A zoom lens driving apparatus achieves the object of driving multiple lens groups by a single motor and low production cost. When a first lens group, which includes a first lens, moves along guide rods, a leading cam of a leading member drives a leading pin of a follower, so that the follower moves a guide pin, and moves a second lens group, which includes a second lens, along the guide rods. The relative distance between the first lens group and the second lens group is controlled by the leading cam.
