Abstract: An image auxiliary data searching and displaying method is used in a document camera. The document camera includes a processor and a user interface. The processor is accessible to a database. The image auxiliary data searching and displaying method includes steps of performing an image-selecting operation on an image of the to-be-displayed object via the user interface to generate a target image, processing the target image by the processor to generate a target characteristic property, searching the database by the processor according to the target characteristic property so as to generate a search result, and simultaneously displaying at least one image auxiliary data from the search result and the image of the to-be-displayed object for comparison.

Abstract: A pointer speed adjusting method is used in a display system including a pen-shaped pointing device and a display screen. The pointer speed adjusting method includes the following steps. Firstly, a moving trajectory of the pen-shaped pointing device is sensed. Then, a trajectory display pattern is obtained according to the moving trajectory. Then, the trajectory display pattern is compared with a reference display pattern shown on the display screen, so that an optical scale factor error is obtained. Afterwards, a speed conversion ratio is adjusted according to the optical scale factor error.

Abstract: A document camera and its light box are provided in the disclosure. The light box includes a base, a light guiding plate embedded in the base, and a light source device movably disposed on the base. The light guiding plate has a light input face and a light output face which are both light transmissive from the base. When the light source device is moved to face the light input face, the light source device provides lights outwards the light guiding plate via the light input face, otherwise, when the light source device is moved away from the light input face, the light source device provides light to the light output face down wards.
