Venus Engine

From Wikipedia, the free encyclopedia
Jump to: navigation, search
The Lumix DMC-F1 was Panasonic's first digital camera to use the Venus Engine.

The Venus processing engine for digital cameras is an image processor 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.


Venus II[edit]

Panasonic claims that their Venus II engine used in the DMC-FZ7 and other cameras has chromatic aberration correction.

Venus III[edit]

In addition to the features claimed for the Venus II, the Venus III engine used in the Lumix DMC-FZ8 and other cameras claims enhanced noise reduction at high ISO numbers and lower power consumption.[citation needed]

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[edit]

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 than earlier versions. It works at 10.1-megapixel resolution. Panasonic published a detailed comparison of Venus III and IV, claiming better noise response by preserving detail, quick-response shutter release time-lag of around 0.008 second minimum and high power-efficiency for Venus IV.

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

Venus HD[edit]

Venus HD is the processing engine used by the first generation Panasonic Lumix DMC-G1 and Panasonic Lumix DMC-GF1 Micro Four Thirds System cameras with large sensor.[1] It supports HDMI output to a high-definition television screen.

Venus V[edit]

As of February 2009 (based on all information available at official Panasonic Lumix Web pages), it appears that the LSI hardware chip-set that Panasonic Lumix refers to as the "Venus Engine V" (when describing the DMC-FX40, see Reference #4[which?] below) is (substantially, if not actually) identical to the LSI hardware chip-set that Panasonic Lumix (also) refers to as the "Venus Engine HD" when describing their (released) DMC-G1, as well in all of the current Panasonic Lumix descriptions of the other (to be) released implementations of this image-processing LSI hardware chip-set (see Reference #5[which?] below).

It appears that the Panasonic Lumix marketing department has chosen to refer to this LSI hardware chip-set primarily using the phrase "Venus Engine HD" as a way to draw attention the capabilities of the included "Motion Picture" mode(s) of the upcoming camera models that will contain the LSI hardware chip-set. However, this choice of marketing phraseology does not (according to Panasonic Lumix's information as currently released) appear to indicate any identifiable difference in the LSI hardware chip-set that they have chosen to (also) identify as "Venus Engine V". This use of dual phraseology appears to have generated a degree of (understandable) confusion on the part of consumers and reviewers awaiting the release of several camera models in 2009 that will (in addition to the already released DMC-G1) feature this LSI hardware chip-set. If, in fact, there exists an identifiable difference(s) (on the level of the internal LSI hardware chip-set) between "Venus Engine HD" and "Venus Engine V", Panasonic Lumix has so far failed to identify it (or them).

Why the Panasonic Lumix marketing department (at the United Kingdom location, at least) has chosen to (in the lone case of the DMC-FX40) refer to the LSI hardware chip-set using the alternate descriptive phrase "Venus Engine V" is unclear, since the DMC-FX40 (as is the case with all the other upcoming models with the exception of the already released DMC-G1) is, indeed, advertised as featuring a "Motion Picture" mode that (it appears) will be a very similar implementation to that of all the other upcoming models to be released that will also include this LSI hardware chip-set. Perhaps the reasoning for this is that the Panasonic Lumix marketing department (at the United Kingdom location, at least) is (in part) describing the DMC-FX40 as a "digital still camera" (despite the fact that it is also specifically advertised as including the above described "Motion Picture" mode(s), see Reference #6[which?] below).

Venus VI[edit]

According to Panasonic, Venus VI adds “Intelligent Resolution”, better Face Recognition and an advanced noise reduction system which applies noise reduction (NR) to luminance noise and chromatic noise separately.

Venus HD II[edit]

According to Panasonic, Venus HD II adds “Intelligent Resolution”, AVCHD Lite at a higher processing speed that utilizes twin CPUs and an advanced noise reduction system that applies noise reduction (NR) to luminance noise and chromatic noise separately. The only difference between Venus HD II and Venus VI are the AVCHD Lite improvements. This engine is used in second-generation Panasonic m43 cameras, the DMC-G2 and G10.

Venus FHD[edit]

This engine is used in third-generation Panasonic m43 MILC's cameras, including the DMC-G3, GF2, GF3, GX1 and the GH-2.

Venus VII FHD[edit]

This engine is used in fourth-generation Panasonic m43 MILC's cameras, including the DMC-G5, G6, GF7, GX7, GM1, GM5 and the GH-3.

Venus IX[edit]

Venus Engine IX is a quad-core processor first introduced in Panasonic's fifth-generation m43 MILC, the GH4, and later used in the FZ1000, LX100 and DMC-G7. In the GH4 the IX processor allows 4K video, 12 fps continuous shooting and 1080p shooting at bitrates as high as 200Mbps.[2]

May 18th Panasonic introduced the G7, which shoots 4K Ultra HD (3840*2160, 24/25/30p) and uses the Venus IX ISP. [3]
