Color extrapolation from monochrome image sensor

A medical device, comprising:

• a sensor configured to:
• capture a first raw image into a first frame of raw pixel values, wherein the first frame of raw pixel values includes first pixel values that represent pixels of a first color;
• capture a second raw image into a second frame of raw pixel values, wherein the second frame of raw pixel values includes second pixel values that represent pixels of a second color;
• and
• capture a third raw image into a third frame of raw pixel values, wherein the third frame of raw pixel values includes third pixel values that represent pixels of a third color;
• and
• a processor and non-transitory computer readable medium storing imaging instructions that, when executed by the processor, causes the processor to:
• combine the first frame of raw pixel values and the second frame of raw pixel values with a first a prior frame of raw pixel values to generate a first extrapolated frame of pixel values in a YCrCb format;
• and
• create a processed image from the first extrapolated frame of pixel values.

An image processing method, comprising:

• capture a first raw image into a first frame of raw pixel values that includes (a) a plurality of first pixel values that represent pixels of a first color and (b) a plurality of second pixel values that represent pixels of a second color;
• capture a second raw image into a second frame of raw pixel values that includes (a) a plurality of third pixel values that represent pixels of the second color and (b) a plurality of fourth pixel values that represent pixels of a third color;
• convolve 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
• create a processed image from the first extrapolated frame of pixel values.
