An '''image processor''' ('''image processing engine''' or '''image processing unit''' ('''IPU''') or '''Image Signal Processor (ISP)'''), also called [[media processor]], is a specialized [[digital signal processor]] (DSP) used for [[image processing]] in [[digital camera]]s, or other devices.<ref>[http://www.robots.ox.ac.uk/~sjrob/Teaching/B4_SP/b4_sp.pdf DIGITAL SIGNAL & IMAGE PROCESSING]</ref><ref>[http://homepages.inf.ed.ac.uk/rbf/BOOKS/VERNON/Chap004.pdf Fundamentals of digital image processing]</ref>
Image processors often employ [[parallel computing]] even with [[SIMD]] or [[MIMD]] technologies to increase speed and efficiency. The [[digital image]] processing engine can perform a range of tasks.
To increase the system integration on embedded devices, often it is a [[system on a chip]] with [[multi-core processor]] architecture.
