Abstract: A method for controlling a graphical user interface (GUI) of a camera application on a portable electronic device is provided. The portable electronic device includes a camera, a touch screen, and a sensor. The method includes the steps of: executing the camera application on the portable electronic device, wherein the GUI includes one or more shutter buttons that control the camera to take a photo; detecting whether the portable electronic device is in a portrait mode or a landscape mode according to sensor data from the sensor; determining positions of the shutter buttons of the GUI in response to the detection result; and rendering the shutter buttons at the determined positions on the GUI displayed on the touch screen.

Abstract: Method for controlling motions and actions of an apparatus including an image capture device having a moving device connected thereto using a controlling device is provided, wherein the moving device is capable of moving the image capture device. The method includes: displaying preview image provided by the image capture device on a display device of the controlling device; detecting inputs to alter the preview image from an input device of the controlling device; obtaining a first image to be captured based on the detected inputs; generating one or more first control commands according to the first image; and transmitting the one or more first control commands to the apparatus via a communication link to control motions and actions of the image capture device and the moving device to capture a second image to be returned, which is the same as the first image, to the controlling device.

Abstract: A method and an apparatus are provided for determining whether a-low resolution image is converted to a high-resolution image, and enhancing image quality of a video signal. The image processing method includes steps of receiving a video stream; determining whether the video stream includes a converted image converted from a low-resolution image to a high-resolution image; and enhancing image quality of the video stream when the video stream includes the converted image.

Abstract: A cumulative function of image is obtained according to its gray levels of pixels. This function is then mapped to obtain a backlight modulation function according to a reference line. The backlight brightness provided for different regions of the liquid crystal display are decided by the backlight modulation function while displaying the images.

Abstract: A block-edge detecting method, for processing an image including a plurality of pixels, includes performing a difference calculation on the plurality of pixels of the image; generating statistic data according to a difference calculation result with an accumulation approach; determining a block width according to the statistic data; and obtaining a plurality of block-edge positions corresponding to the image according to the block width.
