The Venus Engine is an image processing engine for digital cameras. It is developed by Panasonic, and almost all of their Lumix cameras use a version of it. It is based on the Panasonic MN103/MN103S. Image processors operate in four steps: receive data from the CCD sensor, create the Y-color difference signal (image processing), perform JPEG compression, and save the image data. Panasonic claims that its VENUS II processing engine performs all of these simultaneously.
