    摘要： Techniques related to autofocus for imaging devices and, in particular, to generating reliability values associated with phase autofocus shifts are discussed. Such techniques may include performing a curve fitting based on accumulated phase difference values and phase shifts for phase autofocus images and generating a reliability value for a focus phase shift based on the curve fitting.

    摘要： An apparatus and methods for estimating a chromaticity of illumination from raw image data. In an embodiment, one or more image chromaticity weight is determined based on a distance between the raw image data in a sensor chromaticity space and a nearest point within a locus of sensor illumination chromaticities. In a further embodiment, one or more image chromaticity weight is determined based on a disparity among normalized color channel values. In certain embodiments, image chromaticity estimates are utilized to determine a white point estimate for the raw image data. In embodiments, an electronic device including a camera estimates the chromaticity value of raw image data captured by the camera as part of an AWB pipeline. The electronic device may further determine, for example as part of the AWB pipeline, a white point estimate based, at least in part, on the raw image data chromaticity value estimate(s).

    摘要： The invention relates to a method in digital imaging for adjusting exposure, in which one or more exposure parameters (ET, AG) of a camera device are adjusted in connection with imaging. In the method, a histogram formed from a raw image frame (12) is analysed, from which one or more special values (Rhigh, Rlow) are specified and which compared with a target level (Htgt, Ltgt) set for them, and, if a special value (Rhigh, Rlow) differs from the target level (Htgt, Ltgt), the exposure parameters (ET, AG) are adjusted to achieve the target level (Htgt, Ltgt).
