摘要： A vertical color filter sensor group formed on a substrate (preferably a semiconductor substrate) and including at least two vertically stacked, photosensitive sensors, and an array of such sensor groups. In some embodiments, a carrier-collection element of at least one sensor of the group has substantially larger area, projected in a plane perpendicular to a normal axis defined by a top surface of a top sensor of the group, than does each minimum-sized carrier-collection element of the group. In some embodiments, the array includes at least two sensor groups that share at least one carrier-collection element. Optionally, the sensor group includes at least one filter positioned relative to the sensors such that radiation that has propagated through or reflected from the filter will propagate into at least one sensor of the group.

摘要： Methods, devices and computer readable media for implementing novel dominant color alleviation techniques for color balancing are described. The techniques take advantage of unique properties of 2D image data histograms accumulated in a chromaticity space, along with other factors such as estimated scene lux and knowledge of plausible scene illuminant white point values within the chromaticity space. The accumulated 2D image data histograms may be refined and “trimmed,” such that the resultant image data passed to an auto white balance solution has much less influence from the dominant colors in the image, even those that overlap the plausible scene illuminant color region. The described techniques provide for white point estimates that are much less prone to dominant color failures.
摘要翻译：描述了用于实现用于颜色平衡的新型主要颜色减轻技术的方法，设备和计算机可读介质。这些技术利用了在色度空间中累积的2D图像数据直方图的独特性质，以及其他因素，例如估计的场景勒克斯和色度空间内合理场景光源白点值的知识。累积的2D图像数据直方图可以被细化并“修剪”，使得传递到自动白平衡解决方案的合成图像数据对图像中的主要颜色的影响要小得多，即使是与似乎合理的场景光源颜色区域重叠的那些。所描述的技术提供了白点估计，其不太容易出现主要颜色故障。

摘要： An imaging appliance family is a cooperative system of two or more imaging appliances that are linked together to share images, command and control. Imaging appliances may be linked to each other by introducing the appliances to each other, establishing a communications link, and exchanging appliance information. The appliances may be introduced by a number of different manual or auto-sensing triggers, including buttons and presence detect circuits. Communications may be automatically established in response to the introduction. After communications are established, appliance information is exchanged and the appliances are dynamically configured into a cooperative system. Once linked, the appliances remain logically connected until they are removed from the family.

摘要： This disclosure pertains to devices, methods, and computer readable media for improved accuracy of color correction matrix (CCM) coefficient determination based on estimated white point, while maintaining a relatively smooth variation of CCM coefficients over the white point space. The techniques disclosed herein may be achieved via the storage of a limited number of determined CCM multiplier vectors and thus be effective in the camera image pipelines of real image capture devices. With the more accurate CCMs calculated with the disclosed techniques, visible improvement in rendered colors may be achieved as compared to using interpolation from a handful of corner CCMs. The color correction techniques described herein may be implemented by dedicated or general purpose hardware, general application software, or a combination of software and hardware in a computer system.
摘要翻译：本公开涉及用于基于估计的白点提高颜色校正矩阵（CCM）系数确定的精度的装置，方法和计算机可读介质，同时保持CCM系数在白点空间上的相对平滑的变化。本文公开的技术可以通过存储有限数量的确定的CCM乘数向量来实现，并且因此在真实图像捕获设备的相机图像管线中是有效的。利用所公开的技术计算出的更准确的CCM，与使用少数拐角CCM的插值相比，可以实现渲染颜色的可见改善。本文描述的颜色校正技术可以由计算机系统中的专用或通用硬件，通用应用软件或软件和硬件的组合来实现。
