Abstract:
A motion detection method for a display device includes the steps of capturing images from a position on the display device to generate a plurality of capture images, calculating a moving status of the display device according to the plurality of capture images, and adjusting a display range of the display device relative to an image data according to the moving status.
Abstract:
An apparatus for sorting a raw data with horizontal division is provided. The apparatus includes a frame memory and a frame data sorting device coupled to the frame memory. The frame memory stores a frame data having m vertical fields, and each of the vertical fields has n horizontal fields. The frame data sorting device sorts at least one first data block having Vstripe rows of the frame data according to the value n to generate a sorted first data block and overwrites the first data block with the sorted first data block. The frame data sorting device also sorts at least one second data block having Hstripe columns of the frame data according to the value m to generate a sorted second data block and overwrites the second data block with the sorted second data block.
Abstract:
The present invention provides a method of authoring a DVD video recording on an external storage device, the steps of this method comprise; receiving authoring data, the authoring data is used to modify a recording file. The recording file records the authoring of the DVD video recording. Then, modifying the recording file according to the received authoring data on an external storage device until all authoring operations are done. Finally, burning the recording file on a specific area of the DVD.
Abstract:
This invention relates to a chuck engagement lock mechanism which mainly has a chuck head and a lower sleeve holder for clamping a tool such as a drill bit, and a rotatable joint engaged at the side edge of the lower sleeve holder. The lateral side at one end of the rotatable joint and the bottom end face of the chuck head are respectively formed with engaging teeth that can be meshed with each other for adjusting the tightness of clamping from the chuck head to the tool. A rectangular opening is provided at the other end of the rotatable joint for fitting with a hand tool having a lever. Thus, the rotatable joint can be turned by the hand tool so that users can adjust the clamping tightness of the chuck head to the tool conveniently. Thus, the chuck engagement lock mechanism of the present invention has high value in practical application and business competitiveness.
Abstract:
Disclosed is a method for saving electricity consumed by a computer. The method includes the steps of defining a plurality of items of service so that a user can select one of the items of service, identifying at least one device, driver and application corresponding to the selected item of service and providing a simplified process for actuating the device, driver and application corresponding to the selected item of service.
Abstract:
A face detection apparatus and a face detection method thereof are provided. The face detection apparatus includes a rectangle integral image unit, a feature mapping unit and a cascade and score unit. The rectangle integral image unit provides a rectangle integral image according to an original image. The feature mapping unit determines a face candidate region according to rectangular face feature templates, and calculates feature values of the rectangular face feature templates according to the rectangle integral image. The cascade and score unit judges whether the face candidate region conforms to cascade conditions or not, and gives the face candidate region a score according to the feature values when the face candidate region conforms to the cascade conditions. The face candidate region is a non-face region if the score of the face candidate region is lower than a threshold value.
Abstract:
A focusing method, suitable for an image capturing apparatus using in an environment of low brightness, is provided herein. The focusing method includes that an image sensing unit in the image capturing apparatus is wholly or partially divided into a plurality of regions, and digital image data sensed by the image sensing unit is divided into a plurality of sets corresponding to the regions of the image sensing unit. The regional image data corresponding to each of the regions are summed up during the focusing step, so as to obtain a sum of data for each region. Each sum of data is used to calculate a corresponding contrast value, and the contrast value is used to perform calculations for the focusing step, so as to obtain a focus.
Abstract:
A facial expression recognition apparatus and a facial expression recognition method thereof are provided. The facial expression recognition apparatus comprises a gray image generating unit, a face edge detection unit, a motion skin extraction unit, a face contour generating unit and a facial expression recognition unit. The gray image generating unit generates a gray image according to an original image. The face edge detection unit outputs a face edge detection result according to the gray image. The motion skin extraction unit generates a motion skin extraction result according to the original image, and generates a face and background division result according to the motion skin extraction result. The face contour generating unit outputs a face contour according to the gray image, the face edge detection result and the face and background division result. The facial expression recognition unit outputs a facial expression recognition result according to the face contour.
