VENUS Engine
This article is licensed under the GNU Free Documentation License. It uses material from the Wikipedia article "VENUS_Engine".

The Venus processing engine for digital cameras is an image processing engine developed by Panasonic, and almost all of their Lumix cameras use a version of it. 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.

Venus

With the Venus engine, Panasonic claims "super fast"^{cite this quote} shutter speeds and less energy consumption.^{citation needed}

Venus II

Panasonic claims many features^{weasel words} in their Venus II engine,^{cite this quote} including chromatic aberration correction, enhanced resolution, and "super fast" shutter response. An example of a camera that uses the Venus II engine is the Panasonic Lumix DMC-FZ7.^{citation needed}

Venus III

In addition to the enhanced resolution and "super fast" shutter response claimed with Venus II, the Venus III engine has enhanced noise reduction at high ISOs and lower power consumption.^{citation needed} An example of a camera that uses the Venus III engine is the Panasonic Lumix DMC-FZ8.

There have been detailed complaints^who? that the Venus III noise reduction is achieved by smudging the fine image details, and that even in raw mode there is a significant reduction of noise accompanied by loss of fine detail, giving results worse than could be obtained by reducing the noise in a totally raw file by processing with appropriate computer software.^{citation needed}

Venus IV

Panasonic claims that the 2008 Venus Engine IV gives higher-quality images, and includes more accurate detection and better correction for its Optical Image Stabilizer and Intelligent ISO Control functions. It works at 9.1-megapixel resolution. Panasonic have published a detailed comparison of Venus III and IV; better noise response by preserving detail, quick response shutter release time lag of around 0.008 second minimum and high power-efficiency are claimed for Venus IV.

Reviews of cameras which compare the Venus IV engine to Venus III suggest that the newer engine is better, but the issue of noise reduction techniques losing detail remains, though improved^{citation needed}.

Venus HD

The processing engine used by the Panasonic Lumix DMC-G1 Micro Four Thirds System camera with large sensor[1]. Supports HDMI output to a high-definition television screen.
