CCD Camera Chip Set for Portable Equipment Developed Reduced power consumption and the industry's lowest drive voltage achieved
LC99262GL, LC89904V, LC99503/502
Overview
Since it is now possible and useful for portable equipment to provide image-handling functionality, we expect the needs for embedded cameras to grow in the near future. In particular, since data communication capacities are increasing rapidly, there are now stronger incentives to, for example, develop a portable TV telephone by incorporating a camera in a cellular telephone. Due to these directions in the portable equipment market, there are now strong demands for lower costs, further miniaturization, and reduced power consumption in digital camera systems. To respond to these needs, Sanyo has developed a CCD digital camera system IC chip set, consisting of LC99262GL, LC89904V, and LC99503/502, that is optimal for this rapidly expanding portable equipment market. The LC99262GL is a 1/5-inch 330,000-pixel (VGA) CCD that supports both progressive scan and interlaced scan readout. It is provided in a newly-developed miniature leadless package that allows reflow soldering to be used for mounting. The LC89904V is a vertical driver that includes an on-chip voltage step-up circuit that provides the +8 V and -6 V levels required for CCD drive. The LC99503 and LC99502 are CCD controller/signal-processing ICs. The LC99503 is a high-end device that provides two-dimensional outline correction and wide dynamic range signal-processing functions, whereas the LC99502 is a low-cost low-power device. This chip set features the ability to operate from a single-voltage power supply with the industry's lowest supply voltage (+3.3 V) for this type of system. Furthermore, it includes a power management function that can set each functional block in the system to standby mode independently, and thus achieves reduced power consumption. Image quality is improved by achieving smearless imaging by combining a newly-developed CCD drive technique with digital signal-processing technology to eliminate the smear phenomenon (residual images above or below the actual image) that occurs due to imaging conditions such as intense or high-contrast illumination. As a camera system, this chip set
