A medical device that includes a sensor including a filter array. The sensor is configured to capture a raw image and the filter array is configured to filter the raw image into a frame of raw pixel values including first, second, and third pixel values. The medical device includes non-transitory computer readable medium storing demosaicing instructions that, when executed, causes a processor to exclude the first pixel values from the frame of raw pixel values. The processor generates estimated second pixel values at locations of the excluded first pixel values and the third pixel values on the frame, and generates estimated third pixel values at locations of the excluded first pixel values and the second pixel values on the frame. The processor creates a processed image having a partial-resolution frame from the second pixel values, estimated second pixel values, third pixel values, and estimated third pixel values.
