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.
Image processing engines are categorized as follows for each generation. The Venus Engine is a chip based on UniPhierproducts. The image processing engine of the attached RAW image development software is made by Ichikawa Soft Laboratory and outputs images of a trend (Silkypix style) different from those developed by the Venus engine in the camera.
Developed to achieve both high image quality and high speed processing, Venus Engine Plus is based on this chip.
This chip was limited to the top range models, such as the DMC-FZ7. It was developed mainly aiming at high image quality. After this chip (excluding Venus Engine · Plus) the camera shake correction is hardware processed.
This chip was developed for mounting in an entry model. Reproducibility[clarification needed] is inferior to Venus Engine II, but it realizes power saving and high speed processing comparable to Venus Engine 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.
It is a chip realizing power saving based on the Venus Engine II, but we changed high sensitivity shooting, which LUMIX was the most difficult to do, to hardware processing.
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.
Intelligent ISO sensitivity control is changed to hardware processing. By incorporating the iA (Intelligent Auto) function, the name is also set to Random iA.
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. It supports HDMI output to a high-definition television screen.
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" 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.
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".
It is a chip whose cost reduction of Venus engine HD is planned. For that reason, it is enhanced from Venus Engine IV in terms of specifications. 2 CPU configuration, cost reduction, high-speed playback speed, high-precision recognition, power saving, high-speed processing
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. This engine is used in DMC-ZS5 and ZS10.
There are many things in common, but in each case some functions have been added as a minor change from the previous chip.
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/DMC-G10 and DMC-ZS7/DMC-TZ10.
This engine is used in third-generation Panasonic m43 MILC's cameras, including the DMC-G3, GF2, GF3, GX1 and the GH-2.
Based on the Venus Engine HD II, this chip was developed with the aim of strengthening the movie shooting function and achieving high-speed processing.
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.
As a minor change of the previous year's chip, added several functions.
No numbering will be attached after this generation. First adopted in G 5 of Lumix G series.
Suppressing large size noise that was difficult to deal with conventional chips, achieving grain-free image quality. First adopted by G6 of Lumix G series. It is mainly mounted on 4K incompatible models.
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 200Mbit/s.
First adopted by GH4 of Lumix G series.
On May 18 Panasonic introduced the G7, which shoots 4K Ultra HD (3840*2160, 24/25/30p) and uses the Venus IX ISP.
