摘要: A two-by-two pixel array within an image sensor includes a first pixel, a second pixel, a third pixel, and a fourth pixel. A red filter covers the first pixel, a first blue filter covers the second pixel, a second blue filter covers the third pixel, and a green filter covers the fourth pixel. The red filter is configured to allow the first pixel to collect a red component of visible light and prevent the first pixel from collecting blue and green components of the visible light. The first and second blue filters are configured to allow the second and third pixels to each collect the blue component and prevent the second and third pixels from collecting the red and green components. The green filter is configured to allow the fourth pixel to collect the green component and prevent the fourth pixel from collecting the red and blue components.

摘要: An illustrative system includes an image sensor comprising a first pixel, a second pixel, a third pixel, and a fourth pixel. The system further includes a pixel-level broadband infrared cutoff filter that covers the second pixel and that is configured to prevent the second pixel from collecting infrared light having wavelengths included in a first range of wavelengths. The first, third, and fourth pixels are not covered by pixel-level broadband infrared cutoff filters configured to prevent the first, third, and fourth pixels from collecting infrared light having wavelengths included in the first range of wavelengths.

摘要: Systems and methods for reducing noise in a computer-assisted medical system are described herein. In certain illustrative examples, a system may direct an imaging device to capture one or more pseudo dark frame images of an environment of the imaging device. The system may determine a noise pattern within the set of one or more pseudo dark frame images associated with a coupling of the imaging device and an image processing system. They system may process, based on the noise pattern, additional images captured by the imaging device.
