Abstract
A camera according has an interchangeable lens unit removably attached to a camera body, and an image-generating processor that generates image data of a subject captured by the lens unit. A memory provided in the lens unit stores distortion data. The distortion data is associated with an approximation function, which represents the correspondence relationship between image height and distortion aberration. The distortion data includes at least one of: coefficient data of the approximation function, and sample data of the image height and the corresponding distortion aberration. Furthermore, the camera has an approximation function processor that defines an approximation function used to process the image data on the basis of the distortion data read from the memory, and a distortion correction processor that carries out distortion correction processing on the image data based on the aberration distortion calculated for each image point by the defined approximation function.
