IC Media: new integrated, color VGA, single-chip camera.
IC Media Corporation has announced it has expanded its single-chip camera portfolio with the addition of a new single-chip camera, targeted at the video cellular phone and personal digital assistant (PDA (Personal Digital Assistant) A handheld computer for managing contacts, appointments and tasks. It typically includes a name and address database, calendar, to-do list and note taker, which are the functions in a personal information manager (see PIM). ) markets. The new single-chip camera integrates a VGA-resolution (640 x 480 sensor array) CMOS image sensor A CMOS-based chip that records the intensities of light as variable charges similar to a CCD chip. Although initially used in less expensive digital cameras, the quality of CMOS sensors has improved steadily.
CMOS sensors have advantages over CCDs. with a state-of-the-art, color-processing engine. IC Media developed its new camera to mirror the cellular telephone industry's migration from CIF- to VGA-resolution technology.
"We are delighted to announce our newest product so closely on the heels of our recent 2.0 megapixel CMOS camera sensor. These announcements reflect our broad spectrum of technical achievements and our dedication to providing our customers with a wide range of complete visual communications solutions, regardless of application," said Dr. Ben Wu, president and chief executive officer of IC Media.
As cell phone cameras become more and more familiar to the public, quality and resolution become critical. VGA (Video Graphics Array) The display standard for the PC. All PC display adapters support VGA, and Windows machines boot up in "VGA mode" before switching to higher resolutions. resolution provides faster frame-per-second functionality, enabling clearer and faster imaging. IC Media's new cell phone camera, the ICM-205B, is designed for such specific requirements.
IC Media's ICM-205B is a highly integrated single-chip camera. Unique to IC Media's 205B integrated technology is an on-chip, color-processing, proprietary digital signal processor A digital signal processor (DSP) is a specialized microprocessor designed specifically for digital signal processing, generally in real-time computing. Characteristics of typical Digital Signal Processors
The ICM-205B operates at 30 frames per second in a progressive manner. Produced in 0.35-micron 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. technology, the device uses a 1/4" optical system. Pixel size is 6.0-micron x 6.0-micron, giving a sensor area of 5.1 mm x 3.8 mm. The chip includes an on-chip, nine-bit analog-to-digital converter (ADC (1) See A/D converter.
(2) (Apple Display Connector) A peripheral connector from Apple that combines digital video display, USB and power in one cable. ) performing correlated double sampling to improve image quality. The on-chip DSP coverts the sensor output and automatically adjusts exposure time as well as color settings. The ICM-205B also enables the output of different formats (including 8/16-bit YUV The color encoding system used for analog television worldwide (NTSC, PAL and SECAM). The YUV color space (color model) differs from RGB, which is what the camera captures and what humans view. or YCbCr, 16-bit or 24-bit RGB and 8-bit raw data) for the best suitable interface with a cell phone or PDA controller for either embedded or accessory cameras.
IC Media offers a complete line of tools for the ICM-205B, including demo boards and recommended circuit information.
The ICM-205B is currently available in shrunk plastic LCC (11.43 mm x 11.43 mm) packages. Pricing for the ICM-205B is $12.00 in 100,000-unit quantities.
