摘要： Various techniques for lens shading correction are provided. In one embodiment, the location of a current pixel is determined relative to a gain grid having a plurality of grid points distributed in horizontal and vertical directions. If the location of the current pixel corresponds to a grid point, a lens shading gain associated with that grid point is applied to the current pixel. If the location of the current pixel is between four grid points, bi-linear interpolation is applied to the four grid points to determine an interpolated lens shading gain. In another embodiment, a radial gain grid may be provided, and lens shading gains may be interpolated based upon grid points neighboring a current pixel in the radial and angular directions. In a further embodiment, a radial lens shading gain is determined by determining a radial distance from the center of the image to the current pixel and multiplying the radial distance by a global gain parameter based upon the color of the current pixel. The radial lens shading gain is then applied to the current pixel, along with the determined lens shading grid gain or lens shading interpolated gain.
摘要翻译：提供了各种用于镜头遮蔽校正的技术。在一个实施例中，当前像素的位置相对于具有分布在水平和垂直方向上的多个网格点的增益栅格被确定。如果当前像素的位置对应于网格点，则与该网格点相关联的透镜遮蔽增益被施加到当前像素。如果当前像素的位置在四个网格点之间，则将双线性插值应用于四个网格点，以确定内插透镜遮蔽增益。在另一个实施例中，可以提供径向增益栅格，并且可以基于与径向和角度方向上的当前像素相邻的栅格点来内插透镜遮蔽增益。在另一个实施例中，通过确定从图像的中心到当前像素的径向距离并基于当前像素的颜色将径向距离乘以全局增益参数来确定径向透镜阴影增益。然后将径向透镜阴影增益与确定的透镜阴影网格增益或透镜阴影内插增益一起应用于当前像素。

摘要： Systems and methods may employ separate image sensors for collecting different types of data. In one embodiment, separate luma, chroma and 3-D image sensors may be used. The systems and methods may involve generating an alignment transform for the image sensors, and using the 3-D data from the 3-D image sensor to process disparity compensation. The systems and methods may involve image sensing, capture, processing, rendering and/or generating images. For example, one embodiment may provide an imaging system, including: a first image sensor configured to obtain luminance data of a scene; a second image sensor configured to obtain chrominance data of the scene; a third image sensor configured to obtain three-dimensional data of the scene; and an image processor configured to receive the luminance, chrominance and three-dimensional data and to generate a composite image corresponding to the scene from that data.
