Low-Power ISP
Low-Power ISP
The Innosilicon’s Image Signal Processing (ISP)-- ISI700 receives camera sensor data via the 4-channel DVP interface. It is designed for multi-camera, multi-exposure high dynamic range (HDR) image signal processor (ISP) for the mid- to high-end consumer and surveillance market. The ISI700 offers the following functions: It brings advanced imaging technologies and chromatic aberration correction to provide unrivalled image quality and support to a large number of HDR sensor formats.
