A recently granted patent (Publication Number: US11778340B2) describes a method for generating a display scene based on pixel data captured from a single frame. The method involves receiving a single frame that includes a first set of pixel data containing a fluorescence scene component and a second set of pixel data containing a combination of a visible color component scene and the fluorescence scene component. The method then generates a display scene using the first and second sets of pixel data.

The patent also includes additional claims related to the method. One claim involves providing first and second illumination components to illuminate the scene represented by the single frame. The first illumination component includes a fluorescence excitation illumination component, while the second illumination component includes visible light with less than all visible color components of white light.

Another claim describes capturing the single frame using a single-chip image capture sensor with a color filter array. The first set of pixel data is captured with a first set of pixels associated with a first color filter, while the second set of pixel data is captured with a second set of pixels associated with a second color filter.

The method also includes demosaicing the pixel data in different color channels to obtain image pixel data. Based on the image pixel data, the method determines a display fluorescence scene component and a display visible scene component, which are used to generate the display scene.

The patent also includes claims for a system and a non-transitory computer-readable medium storing instructions that perform the method described above.

Overall, this patent describes a method for generating a display scene using pixel data captured from a single frame, allowing for the visualization of fluorescence scenes combined with visible color components. The method utilizes a single-chip image capture sensor with a color filter array and involves demosaicing the pixel data to obtain image pixel data. The generated display scene includes a highlighted scene component corresponding to the fluorescence scene component and a reduced color scene component. The patent also includes claims for a system and a computer-readable medium storing instructions to perform the method.
