A driver status monitor test method is for testing if a driver status monitor generates an alarm operation in accordance with driver motion images. A photographing unit of the driver status monitor is configured to take photographs of the driver motion images. The driver status monitor test method includes a test motion selecting step and a driver motion image displaying step. The test motion selecting step includes selecting at least one test motion for testing the driver status monitor by a user interface. The driver motion image displaying step includes displaying the driver motion images by a display. The driver motion images are a plurality of predetermined image frames in accordance with the test motion. The driver motion images include at least one of a face image, a forelimb image and a torso image.

A headlight optical system and a lamp using the same are provided. The headlight optical system is implemented with the refractive optical system of a single lens. The headlight optical system includes a first incident surface, a second incident surface, and an exit surface. The first incident surface is a horizontal plane. The second incident surface surrounds the first incident surface. The inner edge of the second incident surface is connected with the outer edge of the first incident surface. The second incident surface has an inclined angle with respect to the first incident surface. After the light emitted from the polycrystalline light source is incident on the first incident surface or the second incident surface, the refractive optical system refracts and emits the light from the exit surface.

A multi-eyebox head-up display device and a multilayer combiner are disclosed. The device comprises a projector generates a projected image to a reflector. The reflector generates a reflected image to a multilayer combiner. The multilayer combiner includes at least two superimposed imaging plates, and the semi-reflective surfaces of the superimposed imaging plates are tilted to each other. While the reflected image is projected to the semi-reflective surface of the topmost superimposed imaging plate, the semi-reflective surface of the topmost superimposed imaging plate generates a virtual image. Simultaneously, the reflected image penetrates through the topmost superimposed imaging plate and reaches the lower superimposed imaging plate, and the semi-reflective surface of the lower superimposed imaging plate reflects the light to generate another virtual image. The present invention enables the driver to view the vehicular information at different viewing angles.

An operation method of an adaptive driving beam headlamp system includes: in response to receipt of a sequence of images, when it is determined that a nearby vehicle is in the sequence of images, determining whether the nearby vehicle is in a first condition moving in a direction opposite to a moving direction of a driving vehicle and approaching the driving vehicle, or is in a second condition moving ahead of the driving vehicle in the moving direction of the driving vehicle; calculating a area into which the nearby vehicle is projected to move based on whether the nearby vehicle is in the first or the second condition; and controlling a headlamp to dim a part of a high beam pattern that corresponds with the area.

A flat panel display, an image correction circuit and method thereof are provided. The image correction circuit mainly includes a digital to analog conversion unit and a data processing unit. The digital to analog conversion unit includes a temperature sensor and a gamma voltage generator. The gamma voltage generator is adopted for generating a plurality of gamma voltages, and the temperature sensor is electrically connected to the gamma voltage generator and adopted for sensing the working temperature of the gamma voltage generator. The data processing unit is electrically connected to the digital to analog conversion unit. When the working temperature of the gamma voltage generator changes to higher (or lower) than the room temperature, the data processing unit selects and outputs applicable digital data to the digital to analog conversion unit. Therefore, the digital to analog conversion unit outputs a predetermined gamma voltage at room temperature according to the digital data.
