Crescentec Introduces 4 Megapixel Digital Camera Controller Solutions -- DC1200.Business Editors/High-Tech Writers SAN JOSE, Calif.--(BUSINESS WIRE)--March 25, 2002 Crescentec(R) Corporation, a company providing highly integrated ASIC (Application Specific Integrated Circuit) Pronounced "a-sick." A chip that is custom designed for a specific application rather than a general-purpose chip such as a microprocessor. solutions for digital video and imaging devices, today announced the CT-DC1200 camera controller. The DC1200 is a high performance, high integration single chip digital-still-video and live video camera controller for digital camera manufacturers. The DC1200 is targeted specifically at mainstream multi-megapixel CCD CCD in full charge-coupled device Semiconductor device in which the individual semiconductor components are connected so that the electrical charge at the output of one device provides the input to the next device. and CMOS (Complementary Metal Oxide Semiconductor) Pronounced "c-moss." The most widely used integrated circuit design. It is found in almost every electronic product from handheld devices to mainframes. digital cameras. About the CT-DC1200 The highly integrated DC1200 camera solution will reduce system cost and will also reduce the form factor of today's camera systems. Integrated inside the DC1200 are: baseline JPEG JPEG in full Joint Photographic Experts Group Standard computer file format for storing graphic images in a compressed form for general use. JPEG images are compressed using a mathematical algorithm. compression engine, embedded CPU CPU in full central processing unit Principal component of a digital computer, composed of a control unit, an instruction-decoding unit, and an arithmetic-logic unit. , TV encoder, USB USB in full Universal Serial Bus Type of serial bus that allows peripheral devices (disks, modems, printers, digitizers, data gloves, etc.) to be easily connected to a computer. 1.1 device controller, TFT LCD interface, Audio processor, Real-time-clock and a flexible electronic film interface. Based on the DC-Core(R) architecture that utilizes a pipelined dataflow and a proprietary internal bus scheme, the DC1200 is a highly modular design that provides performance optimization, power management and portability. The device can process and transfer up to a 4Mpixel raw image from the sensor device, at two clocks per pixel at up to a 96MHz clock rate. An on-chip DMA engine can transfer data to an external flash memory/flash card. The DC1200 also integrates a hard-coded image enhancement engine that simplifies user implementation while optimizing performance, power consumption and cost. The image enhancement engine performs statistical collection, color interpolation interpolation In mathematics, estimation of a value between two known data points. A simple example is calculating the mean (see mean, median, and mode) of two population counts made 10 years apart to estimate the population in the fifth year. , Gamma correction, color compensation, edge detection and enhancement, image scaling and many other color processes that are essential to medium and high end digital cameras. Although implemented with hard coded logic, the DC1200 keeps most image parameters and algorithms configurable so that user can set their own image process flow via the internal CPU. Most color parameters such as Auto-Exposure, Auto-White-Balance, Brightness, Contrast, Hue, Saturation, Gamma table and the JPEG quantization (1) The division of a range of values into a single number, code or classification. For example, class A is 0 to 999, class B is 1000 to 9999 and class C is 10000 and above. (2) In analog to digital conversion, the assignment of a number to the amplitude of a wave. table are all programmable. Samples of the DC1200 camera controller are available today. The DC1200 is manufactured with advanced 0.25um CMOS technology and packaged in a 176-pin LQFP See QFP. package. Device drivers for major operating systems and baseline firmware are included. Evaluation boards, reference application software and reference system schematics are available for immediate design in.
