 The OMAP3 processors in Gumstix' Overo COMs have dedicated hardware for capturing and processing data from image sensors. The Caspa camera sensor outputs raw 10-bit Bayer images which is transferred to the Image Signal Processor (ISP) via a parallel interface. The ISP contains various sub-modules that can be exported as Video for Linux (V4L2) devices in /dev. For additional hardware information see the external links section.
