    摘要: The techniques of this disclosure are applicable to backlight display devices. For such devices, the backlight may have different backlight intensity settings in order to promote power conservation. The techniques of this disclosure may apply different adjustments to the display, depending on the backlight intensity setting. In one example, different color correction matrices may be applied for different backlight settings in order to achieve desirable adjustments in the device at the different backlight settings. The adjustments described herein may address chrominance shifts due to different backlight settings as well as cross-talk between color channels. The techniques may also be applicable to organic light emitting diode (OLED) displays that have different luminance settings, and some described techniques may be applicable to displays that have static or fixed luminance output.

    摘要: A method includes determining white balance calibration color ratios for a plurality of illumination sources by using a representative camera of a given type to establish a set of ratios. Because the ratios are fixed for the given camera type, a plurality of cameras of the type may store the fixed ratios, and calibrate by measuring only the reference illumination source. Later white balancing is achieved by using the measured reference illumination source color ratios and the stored fixed ratios as scaling factors to map from the reference illumination source to any other illumination source. The method includes an off-line advance calibration procedure to obtain the fixed ratios, an on-line per camera calibration procedure to obtain color ratios for the reference source, and subsequent white balancing which uses the fixed ratios/scaling factors and the reference source color ratios.

    摘要: A method and apparatus improves an auto focus system by altering, such as by positioning, at least one lens of a digital camera to a plurality of predetermined nonuniform lens positions corresponding to predetermined nonuniform lens position data. The method and apparatus selects a final lens position for the lens based on the predetermined nonuniform lens position data. In one example, a fixed number of predetermined nonuniform lens positions define a set of lens positions used to capture images during an auto focus operation. A final image is captured using a final lens position. The final lens position is determined by comparing focus metric information from each of the frames obtained at the various predetermined nonuniform focus lens positions and selecting the frame with, for example, the best focus metric as the lens position to be used for the final picture or image capture.

    摘要: An apparatus and method are disclosed wherein a depth map is generated using a single camera (e.g., single lens of a camera) and multiple images are captured by the camera. In some embodiments, a single digital camera is used to capture a set of images corresponding to a set of lens positions based on uniform or nonuniform lens position data. The method and apparatus determines focus metric information for each of a plurality of regions of interest in each image of a set. A determination is made of a best lens position for each of the regions of interest based on the focus metric information from the images in the set and are stored as data in a depth map. Image generation operations are then performed based on the generated depth map.

    摘要: An apparatus and method are disclosed wherein a depth map is generated using a single camera (e.g., single lens of a camera) and multiple images are captured by the camera. In one example, a single digital camera is used to capture a set of images corresponding to a set of lens positions based on lens position data. In this example, the lens position data may be either uniform or nonuniform lens position data. The method and apparatus determines focus metric information for each of a plurality of regions of interest in each image of a set. A determination is made of a best lens position for each of the regions of interest based on the focus metric information from the images in the set and are stored as data in a depth map. Image generation operations are then performed based on the generated depth map, such as determining whether or not to use a flash to capture a final image, to determine a type of color operation to be performed on the final image, or any other suitable image generation operation. In one example, the depth map is generated by selecting a best focus metric among the various images that were captured for a particular region of interest. Once the depth map is generated using data from the multiple images, depth map based control logic then determines how to use the depth map to effect an image processing operation. Among other advantages, multiple cameras need not be employed nor do external light sensors need be employed to generate a depth map for use in image processing operations. Other advantages will be recognized by those of ordinary skill in the art.
