Bionz
BIONZ is a line of image processors used in Sony digital cameras. It is currently used in many Sony α DSLR and mirrorless cameras. Image processing in the camera converts the raw data from a CCD or CMOS image sensor into the format that is stored on the memory card. This processing is one of the bottlenecks in digital camera speed, so manufacturers put much effort into making, and marketing, the fastest processors for this step that they can. Sony designs the circuitry of the processor in-house, and outsources the manufacturing to semiconductor foundries such as MegaChips and (mostly) GlobalFoundries, as they currently do not own any fabrication plant capable of producing a system on a chip (SoC). Sony also sources DRAM chips from various manufacturers namely Samsung, SK Hynix and Micron Technology. BIONZ utilizes two chips in its design. The first chip is an SoC that manages overall functionality of the camera such as SD card storage management, wired connection such as USB ...

Image Processor
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. Function Bayer transformation The photodiodes employed in an image sensor are color-blind by nature: they can only record shades of grey. To get color into the picture, they are covered with different color filters: red, green and blue (RGB) according to the pattern designated by the Bayer filter - named after its inventor. As each photodiode records the color information for exactly one pixel of the image, withou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CxProcess III
CxProcess is the trademark of an image processing technology used in Minolta and Konica Minolta digital cameras. Image processing in a camera converts the raw image data from a CCD image sensor into the format that is stored on the memory card. This processing is one of the bottlenecks in the speed of digital cameras. Between 2001 and 2006, CxProcess was used in various Minolta and Konica Minolta digital compact cameras, bridge cameras and DSLRs. In order to distinguish the image processing algorithms from the image processor, the image processor was named SUPHEED (for ''superior image and speed'') since 2003. It can be seen as the predecessor of Sony's Bionz image processor since their taking-over of Konica Minolta's camera business in 2006. CxProcess was originally introduced with the Minolta Dimage 5 in 2001. SUPHEED was introduced with the Minolta Dimage A1 in 2003, which was also the first to implement CxProcess II. Cameras such as the Minolta Dimage 7 series (Dimage 7, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Konica Minolta DG-7D
The Maxxum 7D, labelled Dynax 7D in Europe/Hong Kong and α-7 Digital in Japan and officially named "DG-7D", is a 6.1 megapixel digital single-lens reflex camera, or DSLR, produced by Konica Minolta. It was the top model of their DSLR range; the Maxxum/Dynax 5D consumer-grade model was the other. The 7D was first announced on 2004-02-12 at the PMA show, with full details released just before the 2004 photokina show on 2004-09-15. The production camera was released in late 2004. Production ceased when Konica Minolta announced their exit from the camera business in January 2006. Regardless of its high specification (for the time) and innovative feature set, it came with a very high price tag. The 7D was available as body only, but also with a kit lens; a 17-35mm 2.8. Like the Nikon 18-70 kit lens found with many Nikon DSLRs, this lens was regarded as of high enough quality to do justice to the sensor within the body, unlike the cheap zoom kit lenses found with many DSLRs.

Sony DSLR-A100
Sony α100 (DSLR-A100) is the first digital single-lens reflex camera (DSLR) marketed by Sony in 2006. It is the successor to the previous Konica Minolta DSLR models (primarily the Maxxum/Dynax 5D and 7D) through Sony's purchase of the Konica Minolta camera division. The α100 retains a similar body design and claimed improvements on Konica Minolta's Anti-Shake sensor-shifting image stabilization feature, renamed Super SteadyShot. It uses a 10.2 megapixel APS-C sized CCD sensor. Another notable feature inherited from Konica Minolta is Eyestart, which provides for automatic autofocus activation by detecting the presence of the photographer's eye on the viewfinder, thus quickening the camera's response. Another notable feature is an automatically vibrating CCD to remove dust each time the camera is shut off. The α100 shipped from Sony and resellers by the end of July 2006 with MSRP prices of US$1000 with the 18–70 mm 3.5–f/5.6 kit lens and US$900 for the body only. Th ...

R3000
The R3000 is a 32-bit RISC microprocessor chipset developed by MIPS Computer Systems that implemented the MIPS I instruction set architecture (ISA). Introduced in June 1988, it was the second MIPS implementation, succeeding the R2000 as the flagship MIPS microprocessor. It operated at 20, 25 and 33.33 MHz. The MIPS 1 instruction set is small compared to those of the contemporary 80x86 and 680x0 architectures, encoding only more commonly used operations and supporting few addressing modes. Combined with its fixed instruction length and only three different types of instruction formats, this simplified instruction decoding and processing. It employed a 5-stage instruction pipeline, enabling execution at a rate approaching one instruction per cycle, unusual for its time. This MIPS generation supports up to four co-processors. In addition to the CPU core, the R3000 microprocessor includes a Control Processor (CP), which contains a Translation Lookaside Buffer and a Memory Manag ...

MIPS Technologies
MIPS Technologies, Inc., formerly MIPS Computer Systems, Inc., was an American fabless semiconductor design company that is most widely known for developing the MIPS architecture and a series of RISC CPU chips based on it. MIPS provides processor architectures and cores for digital home, networking, embedded, Internet of things and mobile applications. MIPS was founded in 1984 to commercialize the work being carried out at Stanford University on the MIPS architecture, a pioneering RISC design. The company generated intense interest in the late 1980s, seeing design wins with Digital Equipment Corporation (DEC) and Silicon Graphics (SGI), among others. By the early 1990s the market was crowded with new RISC designs and further design wins were limited. The company was purchased by SGI in 1992, by that time its only major customer, and won several new designs in the game console space. In 1998, SGI announced they would be transitioning off MIPS and spun off the company. After se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RISC
In computer engineering, a reduced instruction set computer (RISC) is a computer designed to simplify the individual instructions given to the computer to accomplish tasks. Compared to the instructions given to a complex instruction set computer (CISC), a RISC computer might require more instructions (more code) in order to accomplish a task because the individual instructions are written in simpler code. The goal is to offset the need to process more instructions by increasing the speed of each instruction, in particular by implementing an instruction pipeline, which may be simpler given simpler instructions. The key operational concept of the RISC computer is that each instruction performs only one function (e.g. copy a value from memory to a register). The RISC computer usually has many (16 or 32) high-speed, general-purpose registers with a load/store architecture in which the code for the register-register instructions (for performing arithmetic and tests) are separate fr ...

32-bit
In computer architecture, 32-bit computing refers to computer systems with a processor, memory, and other major system components that operate on data in 32-bit units. Compared to smaller bit widths, 32-bit computers can perform large calculations more efficiently and process more data per clock cycle. Typical 32-bit personal computers also have a 32-bit address bus, permitting up to 4 GB of RAM to be accessed; far more than previous generations of system architecture allowed. 32-bit designs have been used since the earliest days of electronic computing, in experimental systems and then in large mainframe and minicomputer systems. The first hybrid 16/32-bit microprocessor, the Motorola 68000, was introduced in the late 1970s and used in systems such as the original Apple Macintosh. Fully 32-bit microprocessors such as the Motorola 68020 and Intel 80386 were launched in the early to mid 1980s and became dominant by the early 1990s. This generation of personal computers coincided ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
