    Abstract: Mixed mode imaging is implemented using a single-chip image capture sensor with a color filter array. The single-chip image capture sensor captures a frame including a first set of pixel data and a second set of pixel data. The first set of pixel data includes a first combined scene, and the second set of pixel data includes a second combined scene. The first combined scene is a first weighted combination of a fluorescence scene component and a visible scene component due to the leakage of a color filter array. The second combined scene includes a second weighted combination of the fluorescence scene component and the visible scene component. Two display scene components are extracted from the captured pixel data in the frame and presented on a display unit.

    Abstract translation: 使用具有滤色器阵列的单片图像捕获传感器来实现混合模式成像。 单片图像捕获传感器捕获包括第一组像素数据和第二组像素数据的帧。 第一组像素数据包括第一组合场景，并且第二组像素数据包括第二组合场景。 第一组合场景是由于滤色器阵列的泄漏而引起的荧光场景分量和可见场景分量的第一加权组合。 第二组合场景包括荧光场景分量和可见场景分量的第二加权组合。 从帧中捕获的像素数据中提取两个显示场景分量，并将其显示在显示单元上。

    Abstract: An exemplary method includes a demosaic module receiving a frame of raw pixels having values in a first color space, generating vertical and horizontal color difference signals using information from the frame of raw pixels, generating reconstructed color pixel values for raw pixels that are missing captured color pixel values of a first color component of the first color space, transforming the captured and reconstructed color pixel values of the first color component to brightness pixel values in a second color space, and transforming the vertical and horizontal color difference signals into chrominance pixel values in the second color space.

In certain examples, the demosaic module may transform the vertical and horizontal color difference signals into other pixel values (e.g., chrominance pixel values) in the second color space.

    Abstract: An imaging system processes images of a plurality of objects which have been captured by an image capture device for display. Normal processing of the images is modified as either a function of a depth corresponding to one or more of the plurality of objects appearing in the captured images relative to the image capture device or as a function of the depth and one or more image characteristics extracted from the captured images. A depth threshold may be used to avoid inadvertent modifications due to noise.
