Abstract: A head-up display with variable focal length includes a projector which provides a beam with image, a magnifier lens module which is disposed on the route of the beam, and an array of lens which is movably disposed between the projector and the magnifier lens module. The beam forms an inter-image after passing the array of lens, then forms a virtual image after passing the magnifier lens module. To change the position of the virtual image, adjust the relative position between the array of lens and the magnifier lens module. A dispersion angle of the array of lens is θd, a magnification of the magnifier lens module is M, a distance between the virtual image and user's eyes is VID, a visible range of user's eyes is Et, and satisfies the relationship as following: θd=M*2*cot−1 (2VID/Et).

Abstract: A camera array apparatus including a plurality of cameras and a light deflection module is provided. The cameras are arranged in an array. The light deflection module is disposed on the cameras. The light deflection module includes at least one prism set. The prism set has a plurality of prisms. The prism set is configured to deflect a light entering obliquely with respect to an optical axis of the cameras to at least a portion of the cameras. The angle between the optical axis and the deflected light is smaller than the angle between the optical axis and the light before being deflected.
