Abstract

A shading compensation method of an image capturing device, adapted to an image capturing device having a primary lens, a secondary lens, and a diffuser as well as pre-storing a primary-secondary lenses table and a secondary lens-diffuser table, includes the following steps. First, the secondary lens is covered by the diffuser. A scene is simultaneously captured by the primary lens and the secondary lens covered by the diffuser so as to generate a primary image and a diffused image. Next, according to the primary image and the diffused image, a shading compensation table corresponding to the scene is constructed by using the primary-secondary lenses table and the secondary lens-diffuser table. A shading compensation process is then performed on the primary image according to the shading compensation table so as to generate a compensated image.
