Over the past three years, cellular phones with embedded cameras have progressed from novelty status to mainstream products. Initially, handset makers preferred CMOS image sensors for their low power consumption and ready availability. With the advent of higher resolution camera phones featuring one million pixels or more, the balance of power swung to CCD-based sensors, particularly in Asia. Recent improvements in CMOS technology, however, have initiated a new round of competition between CMOS and CCD that is under way now.
This report provides an update on technology and market issues related to image sensors and camera modules for application in cellular phones, with emphasis on the battle between CMOS and CCD.
Also included is a table that identifies and provides data on image sensors currently offered by leading manufacturers. |
