Abstract: The training method for the phase image generator includes the following steps. Firstly, in each iteration, a loss value is generated, including: (1). the phase image generator generates a plurality of generated phase images using a phase image generation mode; (2). the phase image determiner determines a degree of difference between the generated phase images and original phase images; (3). the loss value of the generated phase images is generated according to the degree of difference. Then, a selector selects a stable loss value from the loss values, and uses the phase image generation mode in the iteration corresponding to the stable loss value as a selected phase image generation mode of the phase image generator.

Abstract: A headlight device includes a light source, a reflection mirror, a Fresnel lens and a blocking plate. The light source and the reflection mirror are disposed on a circuit board. After the light beam emitted from the light source is reflected by the reflection mirror, the light beam is gathered and projected to the Fresnel lens. By the means of the refraction through the Fresnel lens, a light shape which is applied to a vehicle is produced. The blocking plate is configured to produce a light shape with cut-off line.

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.

Abstract: A light collector of a light concentration module includes a first surface, a second surface and at least one light emitting surface. The first surface has multiple microstructures. The microstructures are used for receiving a ray. The second surface is opposite to the first surface. The at least one light emitting surface is adjacent to the first surface and the second surface. The at least one light emitting surface forms a first angle ? with the first surface or the second surface, so as to output the rays received by the microstructures. The light collector satisfies 10°???35° or 85°??<90°.
