Abstract:
A method of generating a color image using a monochromatic image sensor. The method includes sequentially illuminating a surface in a plurality of colors, one color at a time. The monochromatic image sensor captures a plurality of image frames of the surface based on the plurality of colors. The plurality of image frames are identified, and at least one feature in the target of the plurality of image frames is highlighted. Color intensities of the plurality of image frames are normalized. A color intensity map of the target for each of the plurality of image frames is generated. A correlation score is determined by comparing each color intensity map of the plurality of image frames. The color image is generated based on the correlation score.

Abstract:
A medical device includes a sensor, a processor, and non-transitory computer readable medium storing imaging instructions. The sensor captures a first raw image into a first frame of raw pixel values including a plurality of first pixel values that represent pixels of a first color and a plurality of second pixel values that represent pixels of a second color. The sensor captures a second raw image into a second frame of raw pixel values including a plurality of third pixel values that represent pixels of the second color and a plurality of fourth pixel values that represent pixels of a third color. The processor convolves the first frame of raw pixel values with the second frame of raw pixel values to generate a first extrapolated frame of pixel values in a YCrCb format and creates a processed image from the first extrapolated frame of pixel values.
Abstract:
A method is provided for enhancing video images in a medical device. The method includes receiving a first image frame and a second image frame from an image sensor. First image sub-blocks are generated by dividing the first image frame. Second image sub-blocks are generated by dividing the second image frame based on the first image sub-blocks. Histogram data of the first image sub-blocks is generated. Histogram data of the second image sub-blocks is generated based on the histogram data of the first image sub-blocks. A histogram enhanced image frame is generated based on the histogram data of the second image sub-blocks. A video image stream is generated based on the histogram enhanced image frame.
