Single-chip NTSC color camera eases
integration and power requirements
Based on the company's ColorMOS technology, the VV6405 color camera
was offered as the first color NTSC camera to integrate complete functionality
on a single standard CMOS chip. The chip draws 70% to 80% less power than
charge-coupled devices and offers greater ease of integration over alternative
CCD solutions, according to the company.
Offered as providing greater ease of integration over alternative
CCD solutions, the VV6405 color camera was introduced as the first color
NTSC camera to integrate complete functionality on a standard CMOS-chip.
Combining image-sensing and image-processing functions, the camera delivers
NTSC composite video using a single external crystal and a single-rail
5-V supply. Power consumption is 100 mA at 5 V. The part features 320 x
240 active pixels and produces quality color images in light conditions
ranging from 100,000 lux down to 50 lux.
Housed in a standard 48-pin LCC, the chip features a 1/4-in. ColorMOS
photoplane, video-timing controller, 8-bit A/D converter, 300-MIPS color-DSP
engine, and D/A converter for driving 75 ohm. It also includes five
video-line memories, auto exposure control, and color balance, as well
as an NTSC composite video encoder. (Lensed unit, $65 ea/prod qty–available
now.)
