摘要： Apparatus are provided, including an autofocus mechanism. The autofocus mechanism includes an autofocus preliminary operation mechanism and an autofocus continuation mechanism. The autofocus preliminary operation mechanism starts an autofocus of a lens assembly on a given target by causing a focus quality determiner to determine the quality of focus of the lens assembly on the given target while the position of the lens unit is in one focus range and causing an adjustment controller to effect a preliminary adjustment of the lens assembly position within the same one focus range. The autofocus continuation mechanism automatically, upon a lack of successful focus by the autofocus preliminary operation mechanism, continues an autofocus of the lens assembly on the given target by causing the adjustment controller to effect a continued adjustment of the lens assembly position from the one focus range to a different focus range while the focus quality determiner continues to determine the quality of the focus.

摘要： The disclosure describes flicker detection and correction techniques to improve the quality of captured imagery, such as video or still images. In particular, this disclosure describes flicker correction techniques that compare different image frames to detect flicker. In some embodiments, the comparisons involves summing intensity values associated with rows within the frames and comparing the row sums to generate a difference signal. Detection and correction of flicker may be performed using a first derivative of the difference signal. The first derivative of the difference signal can be used in variety of ways to detect and correct flicker.

摘要： An imaging system generates a gain for a component of an image format. The gain is at least partially dependent on the brightness of the light source illuminating a scene when an image of the scene was generated. The gain can be used to correct the component of the image format for the color shift in the image caused by the light source. In some instances, the imaging system generates a gain for a plurality of the components of the image format or for all of the components of the image format. The gains can be used to correct the components for the color shift in the image caused by the light source.
摘要翻译：成像系统为图像格式的分量生成增益。当生成场景的图像时，增益至少部分地取决于照亮场景的光源的亮度。增益可用于校正由光源引起的图像中颜色偏移的图像格式的分量。在一些情况下，成像系统为图像格式的多个分量或图像格式的所有分量生成增益。增益可以用于校正由光源引起的图像中的颜色偏移的分量。
