    Abstract: A translator pen and a translation method using same are provided. The translator pen includes a housing and a pen head. The housing forms a first accommodation cavity adapted to accommodate an image collector. An outer contour of the pen head is formed into a tapered shape, an outer diameter of the pen head gradually decreases along a direction of the pen head away from the housing and forms a second accommodation cavity adapted to accommodate a pen core. At least a portion of the end of the housing, which does not form the pen head, forms an inclined surface. The inclined surface is inclined relative to the outer contour of the pen head toward an outside of the housing along a direction of the housing away from the pen head. The image collector is configured to face the inclined surface.

    Abstract: A method for controlling rotation of an image displayed in a display screen includes establishing a coordinate system with an origin being set at a center of the display screen. The coordinate system includes a coordinate plane in parallel to an average plane associated with the display screen. The method further includes dividing the coordinate plane to four azimuth intervals corresponding respectively to four display modes with four boundary lines being all intersected at the origin of the coordinate system. Additionally, the method includes defining a respective buffer region in a respective angular range around a respective boundary line. Furthermore, the method includes determining whether an azimuth angle of a gravity acceleration vector component in the coordinate plane is kept in a respective azimuth interval corresponding to a current display mode of the image including two buffer regions respectively associated with two boundary lines of the respective azimuth interval.
