Abstract
According to various embodiments, the system and method disclosed herein serve to at least partially compensate for departures of an actual main lens of a light-field camera from the properties of an ideal main lens. Light-field data may be captured and processed through the use of product calibration data and unit calibration data. The product calibration data may be descriptive of departure of a main lens design of the light-field camera from an ideal main lens design. The unit calibration data may be descriptive of departure of the actual main lens of the light-field camera from the main lens design. Corrected light-field data may be generated as a result of the processing, and may be used to generate a light-field image.
