Abstract

See full text

A camera testing system for determining performance of a camera comprising an imaging sensor and a lens, the system comprising a processing system comprising at least one processor and memory. The processing system may be configured to: control the camera to capture, using the imaging sensor, a first image through the lens of a target disposed at a first distance from the camera; determine a first modulation transfer function (MTF) value from the first image; control the camera to capture, using the imaging sensor, a second image through the lens of the target disposed at a second distance from the camera that is different from the first distance; determine a second MTF value from the second image; and determine performance of the camera based on the first MTF value, the second MTF value and a difference between the first MTF value and the second MTF value.
