Abstract:
Embodiments of the invention include an apparatus including an enclosure configured to receive an endoscope having an electromagnetic radiation sensor. The apparatus also includes an electromagnetic radiation source having at least a portion disposed within the enclosure. The electromagnetic radiation source is configured to emit electromagnetic radiation based on a calibration instruction. The electromagnetic radiation sensor is configured to receive at least a portion of the electromagnetic radiation when at least a portion of the endoscope is coupled to the enclosure.
Abstract:
A method of calibrating an image sensor may include detecting a response from a pixel of the image sensor as a result of light having an intensity impinging on the pixel, and measuring the actual standard deviation of the response of the pixel at the intensity of light. The method may also include determining an averaging number for the pixel at the intensity. The averaging number may be a number of responses of the pixel at the intensity to be averaged to attain an average response having a standard deviation less than or equal to a target value. The method may further include determining the average response of the pixel using the determined averaging number.

Abstract:
In one embodiment, an imaging method may include receiving an intensity value of a first spectral channel associated with a pixel location. The intensity value of the first spectral channel may be based on electromagnetic radiation reflected from an object after being emitted from a narrow-band electromagnetic radiation source. The method may further include defining an intensity value of a second spectral channel based on the intensity value of the first spectral channel. The second spectral channel may be associated with a spectral region of electromagnetic radiation different from a spectral region of electromagnetic radiation associated with the first spectral channel. The method may also include associating the intensity value of the second spectral channel with the pixel location.
