Abstract: A camera having a gyro and accelerometer stabilizes a video recording by the following steps. First, gyro data and acceleration data are synchronized with a frame of video data. The gyro data and the acceleration data are fused together to get a space domain rotation matrix that corresponds to the frame. The frame is adjusted based on the space domain rotation matrix. Next, at least one feature of the adjusted frame is detected. A modified rotation matrix is determined by comparing the at least one detected feature of the adjusted frame with a corresponding feature in a neighboring frame of the video data. Finally, the adjusted frame is further adjusted based on the modified rotation matrix.

Abstract: A photography data sharing method adapted to be used with a network sharing system. The network sharing system is configured to store and analyze at least a photography data. Each photography data includes an event information about the respective photography shooter generating the photography data. The network sharing system includes a database, a processing unit and a browser interface. The photography data sharing method includes steps of: storing the photography data; analyzing the event information of the photography data; determining whether the photography viewer and the event information of the photography data belong to a same event or not when the photography viewer is trying to browse the photography data through the browser interface; and providing the photography data to the photography viewer through the browser interface when it is determined that the photography viewer and the event information of the photography data belong to the same event.

Abstract: The present invention discloses a method to define a drafting range based on a curve with a plurality of points drawn by a user. A writing character is shown in a display based on the drafting range. The method includes the following steps. The first step is to gather coordinate positions of points. Then, these coordinate positions are compared to each other to get a maximum coordinate position and a minimum coordinate position. A drafting range is generated based on the maximum coordinate position and the minimum coordinate position. Next, the drafting range is corresponded to a display range of a display to define a ratio of the drafting range to the display range. Finally, the writing character is adjusted and displays in the display based on the ratio.

Abstract: The present invention discloses a method to automatically arrange word string in a display. The word string includes two words. The method includes the following steps. The first step is to define the positions of the start position and the stop position of strokes of the two words. The second step is to group the start position and the stop position based on a threshold value. The third step is to circle the words based on the grouping result. The final step is to rearrange the two words based on a datum point.

Abstract: A wireless control device and a multi-cursor control method for use with a computer system are provided. The application program of the computer system is executed to generate at least a first pointer and a second pointer. The wireless control device includes a first pointer controller, a second pointer controller and a wireless transceiver. The multi-cursor control method includes steps of issuing a first wireless control signal containing a first identification code in response to manipulation of a first user, issuing a second wireless control signal containing a second identification code in response to manipulation of a second user, receiving and transmitting the first wireless control signal and the second wireless control signal to the computer system, and controlling corresponding shifts of the first pointer and the second pointer defined in the application program according to the first identification code and the second identification code, respectively.

Abstract: The six-direction button includes a base, a rotation detector having a rotation pin disposed on the base, a button cover coupled with the rotation pin, and four pressure detectors disposed on the base under the button cover. The button cover and the rotation pin may be rotated clockwise or counterclockwise. The pressure detectors are arranged according to an up side, a down side, a left side, and a right side of the button. The cover button cover may touch one of the four pressure detectors when the button cover is pressed.

Abstract: A document camera is used for capturing and outputting images of an object to be displayed. The document camera is detachably coupled with a presentation station module and includes a main body, a camera module, a first operating panel and an expansion interface. The camera module is disposed on the main body for capturing the images of the object. The first operating panel is disposed on the main body and operated by a user to control an image-capturing operation of the camera module and an image outputting operation. The expansion interface is disposed on the main body. The functions of the document camera are expanded when the camera module is coupled with the presentation station module via the expansion interface.

Abstract: A document positioning apparatus has a supporter. The supporter is disposed under a base of a document camera. A gap is formed between the supporter and a ground surface used to support the supporter and the gap is designed to be large enough for a document to shift. The document positioning apparatus further has a document guider, formed on an edge of the supporter to guide the document into the gap under the supporter easily.

Abstract: A transmission mechanism that can be applied in a document camera is disclosed. The transmission mechanism includes a first roller, a second roller, a first lever and second lever. The first roller and the second roller rotate about individual axes. Ends of the first lever are pivoted about the axis of the first roller and the axis of the second roller, respectively; and ends of the second lever are pivoted about a shift point of the first roller and a shift point of the second roller, respectively. The first lever and the second lever are uncrossed.

Abstract: A document camera with light compensation functionality includes a camera securing to a base. The document camera has an emitting-adjustable light source. A sensor, installed on top of the camera, measures the light in the surroundings and outputs an analog signal. A converter transforms the analog signal into a digital signal. A light-computing unit receives the digital signal and produces a signal including an optimum light condition. A light controller controls the intensity of the light of the emitting-adjustable light source according to the signal including the optimum light condition outputted from the light-computing unit.
