Milbeaut

Last updated

The Socionext Milbeaut image/video processors are media processors in multi-processor system on a chip architecture. [1] [2] Started by Fujitsu with the M-1 Series in 2000 each generation (2013: 7th) has several variants regarding included modules and processor-cores, built for mobile phones, digital compact cameras, MILCs and DSLRs like Leica M (Typ 240) and Leica S2, [3] Nikon DSLRs (see Nikon Expeed), some Pentax K mount [4] cameras and for the Sigma True-II processor. [5]

Technology

Multiple FR-V processor cores, with even each single processor-core able to compute many instructions/operations in parallel are used for image- and video-processing. Storage- and display-interfaces and other modules are added and a digital signal processor (DSP) increases the number of simultaneous computations.

An on-chip 32-bit Fujitsu FR microcontroller (6th generation in 2011 introduced the dual-core ARM architecture) initiates and controls the operation and data transfers of all processors, modules and interfaces and can be seen as the main control unit of the camera. The Milbeaut is also used as an application-specific integrated circuit (ASIC) or application-specific standard product (ASSP).

The 7th generation uses a 55  nm low-power process (SuVolta) and ARM Cortex-A5 microcontroller. [6]

Digital camera Camera that captures photographs or video in digital format

A digital camera is a camera that captures photographs in digital memory. Most cameras produced today are digital, largely replacing those that capture images on photographic film. Digital cameras are now widely incorporated into mobile devices like smartphones with the same or more capabilities and features of dedicated cameras. While there are still dedicated digital cameras, many more cameras are now incorporated into mobile devices like smartphones. High-end, high-definition dedicated cameras are still commonly used by professionals and those who desire to take higher-quality photographs.

System on a chip Integrated circuit that incorporates the components of a computer

A system on a chip is an integrated circuit that integrates all or most components of a computer or other electronic system. These components almost always include a central processing unit (CPU), memory, input/output ports and secondary storage, often alongside other components such as radio modems and a graphics processing unit (GPU) – all on a single substrate or microchip. It may contain digital, analog, mixed-signal, and often radio frequency signal processing functions.

Pentax Japanese optics company and brand owned by Ricoh

Pentax is a brand name used primarily by the Japanese multinational imaging and electronics company Ricoh for DSLR cameras, lenses, sport optics, and CCTV optics. The Pentax brand is also used by Hoya Corporation for medical products & services, TI Asahi for surveying instruments, and Seiko Optical Products for certain optical lenses.

APS-C Image sensor format

Advanced Photo System type-C (APS-C) is an image sensor format approximately equivalent in size to the Advanced Photo System film negative in its C ("Classic") format, of 25.1×16.7 mm, an aspect ratio of 3:2 and Ø 31.15 mm field diameter. It is therefore also equivalent in size to the Super 35 motion picture film format, which has the dimensions of 24.89 mm × 18.66 mm and Ø 31.11 mm field diameter.

In photography, through-the-lens (TTL) metering refers to a feature of cameras whereby the intensity of light reflected from the scene is measured through the lens; as opposed to using a separate metering window or external hand-held light meter. In some cameras various TTL metering modes can be selected. This information can then be used to set the optimal film or image sensor exposure, it can also be used to control the amount of light emitted by a flash unit connected to the camera.

FR-V (microprocessor)

The Fujitsu FR-V is one of the very few processors ever able to process both a very long instruction word (VLIW) and vector processor instructions at the same time, increasing throughput with high parallel computing while increasing performance per watt and hardware efficiency. The family was presented in 1999. Its design was influenced by the VPP500/5000 models of the Fujitsu VP/2000 vector processor supercomputer line.

Image processor Specialized digital signal processor used for image processing

An image processor, also known as an image processing engine, image processing unit (IPU), or image signal processor (ISP), is a type of media processor or specialized digital signal processor (DSP) used for image processing, in digital cameras or other devices. Image processors often employ parallel computing even with SIMD or MIMD technologies to increase speed and efficiency. The digital image processing engine can perform a range of tasks. To increase the system integration on embedded devices, often it is a system on a chip with multi-core processor architecture.

Mirrorless camera Compact camera with a user-removable and replaceable lens

A mirrorless interchangeable-lens camera (MILC) or simply mirrorless camera, also called digital single-lens mirrorless (DSLM) or electronic viewfinder interchangeable lens (EVIL) camera, is a photo camera featuring a single, removable lens and a digital display. The camera does not have a reflex mirror or optical viewfinder like a digital single-lens reflex (DSLR) camera. Many mirrorless cameras retain a mechanical shutter. Like a DSLR, a mirrorless camera accepts any of a series of interchangeable lenses compatible with its lens mount.
