Isp(Image Signal Processor) - LG KF600d Service Manual

3.13. ISP(Image Signal Processor)

MV9319 is high-end Image Signal Processor (ISP) supporting image sensors up to 5 mega pixels.
MV9319 can be applied to various image sensor modules and camera applications. MV9319 is
especially suitable for camera phones or smart-phones with built-in MCP (Mobile Camera
Processor) or MMP (Mobile Multimedia Processor). Its powerful image processing functions such as
edge enhancement, color correction, advance interpolation, Auto White Balancing significantly
increases the quality of sensor image. Moreover, real time JPEG output mode in MV9319 makes
Back-end processor easier to capture and process JPEG image. MV9319 also supports various
serial interfaces to communicate with external device flexibly. MV9319 is the best solution to create
high image quality for camera phones demanding high performance.
