Systems and methods for reducing noise in imagery in a computer-assisted medical system

A method comprising:

• directing, by a computing device, an imaging device to capture a pseudo dark frame image of an environment of the imaging device, the directing comprising directing the imaging device to capture an image of the environment of the imaging device using a minimal exposure time of the imaging device;
• determining, by the computing device, a noise pattern within the pseudo dark frame image associated with a coupling of the imaging device and an image processing system;
• and
• performing, by the computing device, an operation based on the noise pattern.

A system comprising:

• an imaging device interface;
• and
• a processor configured to:
• direct, after an imaging device is coupled to the imaging device interface, the imaging device to capture a pseudo dark frame image of an environment of the imaging device, the directing comprising directing the imaging device to capture an image of the environment of the imaging device using a minimal exposure time of the imaging device;
• determine a noise pattern within the pseudo dark frame image associated with the system and the imaging device coupled to the imaging device interface;
• and
• process, based on the noise pattern, additional images captured by the imaging device coupled to the imaging device interface.

A non-transitory computer-readable medium storing instructions executable by a processor to:

• direct an imaging device to capture a set of one or more pseudo dark frame images of an environment of the imaging device, the directing comprising directing the imaging device to capture an image of the environment of the imaging device using a minimal exposure time of the imaging device;
• determine a noise pattern within the set of one or more pseudo dark frame images associated with a coupling of the imaging device to an image processing system;
• and
• provide the noise pattern for processing of additional images captured by the imaging device.
