摘要： Systems, methods, and devices for dual processing of raw image data by main image processing and alternative image processing capabilities of an electronic device are provided. According to an embodiment, alternative image processing may analyze a first copy of a frame of raw image data before a second copy of the frame of raw image data is processed by main image processing. Thereafter, the main image processing may process the second copy of the frame of raw image. The main image processing may be calibrated based at least in part on the analysis of the first copy of the frame of raw image data.

摘要： Systems, methods, and devices for applying lens shading correction to image data captured by an image sensor are provided. In one embodiment, multiple lens shading adaptation functions, each modeled based on the response of a color channel to a reference illuminant, are provided. An image frame from the image data may be analyzed to select a lens shading adaptation function corresponding to a reference illuminant that most closely matches a current illuminant. The selected lens shading function may then be used to adjust a set of lens shading parameters.

摘要： Systems, methods, and devices for obtaining a properly exposed strobe-illuminated image are provided. One method for doing so may include, for example, gathering image capture statistics during a first period when a strobe is not emitting light and during a second period when the strobe emits a preflash. These image capture statistics may include distinct image capture control statistics and luma values associated with the periods. Final image capture control statistics then may be determined based at least in part on the first luma value normalized to the first image capture control statistics and the second luma value normalized to the second image capture control statistics. Thereafter, the final image capture control statistics may be used to capture a properly exposed strobe-illuminated image when the strobe emits a main flash.
摘要翻译：提供了用于获得正确暴露的频闪照明图像的系统，方法和装置。一种这样做的方法可以包括例如在闪光灯不发光的第一时段期间和当闪光灯发出预闪光的第二时段期间收集图像拍摄统计。这些图像捕获统计可以包括不同的图像捕获控制统计和与周期相关联的亮度值。然后可以至少部分地基于归一化为第一图像捕获控制统计的第一亮度值和归一化为第二图像捕获控制统计的第二亮度值来确定最终图像捕获控制统计。此后，当闪光灯发出主闪光时，最终的图像捕捉控制统计可用于捕获正确曝光的闪光灯照明图像。

摘要： Techniques for accomplishing transitions between graphical data representations (e.g., charts, graphs, and so forth) are disclosed. In accordance with these techniques, each object in such a graphical data representation is individually manipulable during transitions. In certain embodiments, the presence of an object in both the outgoing and incoming graphical data representation may be taken into account during a transition. In such embodiments, differences between the objects in the outgoing and incoming graphical data representation may be addressed by the respective transition.

The method comprises acquiring video images of colored light, and measuring a light intensity response of the video camera to the colored light. The method further comprises comparing the intensity of the measured response to a desired colored light intensity for determining a color intensity bias and storing the intensity bias for the colored light in the camera so that the bias can be applied when the camera is operating at an arbitrary lighting condition.
