Abstract: A method for focusing on an object to capture an image of that object is provided. The method includes obtaining the travel time between the point in time that an ultrasonic signal is sent and the point in time at which the reflected signal is received. The method also includes obtaining environment information of the electronic device based on location/position information. The method further includes determining local sound speed according to environment information and determining the distance to an object using the local sound speed and the travel time. In addition, the method can include focusing on the object according to the object distance.

Abstract: Techniques and implementations related to automatic image capture during preview, as well as recommendation of images, are described. A method for operating an electronic apparatus may involve receiving a stream of one or more preview images in a preview mode of the electronic apparatus. The method may also involve determining whether any preview image of the stream of preview images is valuable. The method may further involve controlling an operation of the electronic apparatus in response to the determining.

Abstract: An electronic device and a method for setting a sensor are provided. The electronic device includes a sensor and a processor. The processor is coupled to the sensor and configured to calculate a plurality of groups of candidate sensor settings every calculation cycle, wherein each calculation cycle includes one or more frames, and each of the groups of candidate sensor settings corresponds to one respective frame of the calculation cycle. Every frame of the calculation cycle, the processor is further configured to determine a respective group of adoptable sensor settings for each frame of the calculation cycle according to the plurality of groups of candidate sensor settings, wherein the respective group of adoptable sensor settings is for provision to set a sensor.

Abstract: A photographic system and an associated image tuning method are provided. The image tuning method includes the steps of: capturing an image by an image sensor of the photographic system; analyzing an image content of the captured image to obtain a plurality of candidate images using a preference search strategy; providing the plurality of candidate images for selection by a user of the photographic system; determining an output image based on one of the candidate images selected by the user; and adjusting the preference search strategy by using the user's selection.

Abstract: Image capture methods and systems. First image data with an environmental light source is captured, and second image data with a pre-flash light source of a strobe is captured. During image capture, each pixel therein is respectively performed with a white balance adjustment according to the first and the second image data.

Abstract: A digital camera for determining the chromaticity coordinates and the related color temperature of an object and the method thereof. A photosensor receives the reflected light of the object and outputting image data. An averaging unit outputs the red average, the green average and the blue average according to the image data. A chromaticity coordinate unit transforms the red average, the green average and the blue average into tristimulus values using a transformation matrix and outputs a chromaticity coordinate according to the tristimulus values. A color temperature unit outputs the color temperature according to the chromaticity coordinates.

Abstract: The invention provides a device and method to determine the exposure setting for an image of a scene with human-face area. Human-face-contour-like patterns are provided in advance. The human-face area of the scene is approximately determined according to a rule, and the specific unit of an exposure metering matrix for the image is also determined. The specific unit relates with the human-face area in the scene. Changing the weighting of the specific unit helps to modify the exposure metering matrix. The exposure setting of the image being captured is then determined according to the modified exposure metering matrix.
