The Sony HVR-A1 is the entry level HDV camcorder that records high definition video as well as DVCAM and DV standard-definition video. The camera uses a single three million pixel CMOS chip to capture images. The use of a CMOS (Complementary Metal Oxide Semiconductor) chip allows the camera to capture amazing high quality images while consuming less battery power and making the camera smaller overall. The Enhanced Imaging Processor (EIP), a Sony created technology, enables the camcorder to capture and process high-definition video and high resolution still images with the highest levels of contrast and detail. See the Most with CMOS The HVR-A1U realizes new levels of compact design and efficiency with a single 3 megapixel CMOS imaging chip. Compared to a CCD (Charged Coupled Device), a CMOS (Complementary Metal Oxide Semiconductor) works more efficiently and burns less battery power. It uses both positive and negative
