Abstract

An efficient image capture system is disclosed that integrates functions to control a lens including one or more of focus or object distance, zoom, temperature compensation, and stabilization within an image signal processor (ISP) with appropriate algorithms. In particular, the integrated ISP circuitry may control the motion of the focus and zoom optics of an optical assembly, control stabilization, control the flash, provide enhanced functions and features for controlling the zoom and focus lenses to enable enhanced image capture sequences and/or tracking lens data, provide a set of algorithms within the ISP to alter the aspect ratio (both height and width of an image) of the image, for example to compensate for the addition of an anamorphic lens, and integrate an anamorphic lens into the module to alter an image's projected aspect ratio onto the focal plane array.
