1. An endoscope system comprising:
an image sensor comprising an image sensor output; and
a processing device comprising an input connected to the image sensor output, the processing device is configured to:
consecutively receive at a first frame rate, via the input, frames captured by the image sensor;
receive a first capture signal, indicative of an operator performing a first action associated with capturing a still image of the frames received via the input;
receive a second capture signal after receipt of the first capture signal, indicative of the operator performing a second action associated with capturing the still image of the frames received via the input;
temporarily store a first plurality of frames of the frames received via the input after receipt of the first capture signal, wherein the first plurality of frames are frames received via the input after receiving the first capture signal, wherein, in accordance with more than a first number of frames being received via the first input between receipt of the first capture signal and receipt of the second capture signal, the first plurality of frames consists of the first number of frames received via the first input immediately prior to receipt of the second capture signal, and wherein, in accordance with less than the first number of frames being received via the first input between receipt of the first capture signal and receipt of the second capture signal, the first plurality of frames consists of the first plurality of frames received via the first input after receipt of the first capture signal, the first plurality of frames including, additionally, frames received after receipt of the second capture signal;
determine one or more quality properties of each of the first plurality of frames; and
select a designated frame of the first plurality of frames based on the one or more quality properties.
