Systems and methods for lens characterization

摘要

Methods and systems for analyzing camera lenses and presenting information regarding camera lenses performance are described. An interactive user interface is provided over a network for display on a user terminal by a computer system. A user request is received at the computer system from the user terminal for lens data from a first lens. Lens data, including test data obtained via a first digital image captured using the first lens at the first focal length setting and the first aperture setting is accessed from memory and transmitted to interactive user interface. The interactive user interface is configured to display an identification of the first camera body, an identification of the first lens, the first focal length setting used to capture the image, and the first aperture setting used to capture the image. Using the lens test data, the interactive user interface generates and displays sharpness graph data.

主权项

1. A method comprising:
receiving over a network at a computer system a user request for lens performance data for a first lens from a user terminal, wherein the first lens comprises an optical lens; providing for display on the user terminal an interactive user interface; accessing from computer readable memory, via the computer system, lens data corresponding to the user request, wherein the lens data includes test data obtained via a first digital image frame captured using the first lens with a first focal length setting using a first aperture setting, and where the lens data includes chromatic aberration data; and transmitting the lens data to the interactive user interface, and enabling the interactive user interface to:
display an identification of the first lens;display the first focal length setting used to capture the first digital image frame;display the first aperture setting used to capture the first digital image frame;render a sharpness plot for the first lens, wherein the sharpness plot includes sharpness plot data generated at least partly based on the lens data by mapping sharpness to frame locations; andrender a chromatic aberration graph for the first lens, wherein the chromatic aberration graph includes chromatic aberration graph data corresponding to at least one portion of the first digital image frame.
