Sony is expanding its lineup of HDV products for professionals with the new HVR-A1U model, based on a 1/3-inch, 3-megapixel Complementary Metal Oxide Semiconductor (CMOS) imager.
Sony has improved upon the key attributes of traditional CMOS sensors with proprietary technology, & this innovative CMOS device is also accompanied by Sonys EIP, which enables the high-speed processing required for capturing high-definition video images, & allows an HDV camcorder to record & playback high-quality still images.
The first professional high-definition application of this enhanced imaging technology is in the HVR-A1U model. EIP technology is also at the core of a new consumer product counterpart, the Sony HDR-HC1 Handycam.
The combination of a 3-megapixel CMOS sensor with Sony's Enhanced Imaging Processor enables a camcorder to capture & process high-definition video & still images with unprecedented levels of gradation & detailed image reproduction.
Building on Sony's long history of imager & camera development, Sony is now offering customers yet another option to choose from among the many diverse HD acquisition tools in the Sony product family.
The HVR-A1U HDV camcorder complements Sonys first entry into the professional HDV market, the HVR-Z1U. Introduced last fall, more than 37,000 units of Sony HDV products have already been delivered to customers worldwide.
The new HVR-A1U model now offers professional videographers another option for the capture and playback of HD images. The HVR-A1U offers many of the same features as the HVR-Z1U, such as balanced audio, XLR inputs, SMPTE timecode and a Carl Zeiss Vario-Sonnar T* Lens. However, its smaller footprint makes this camcorder ideal for applications where space is at a premium or extreme mobility is required. For example, potential applications may include mounting on a skydivers helmet or placement on the hood of a racecar.
Sonys CMOS sensor produces natural and rich tones for both light and dark areas of an image. To achieve wide dynamic range, EIP technology employs an algorithm that separates image data into its texture patterns and brightness components.
CMOS-based technology helps eliminate the presence of smear, which is created by vertical bands of bright light stretching from the top to the bottom of an images "bright areas" and occurs when something extremely bright like a pin-point light source is shot.
Sony has reduced the size of the transistors within an images pixel matrix, allowing for a larger area of the photo-sensitive portion of the pixel and enabling more light to be taken in than with a conventional CMOS sensor. In addition, the Correlated Double Sampling circuits on the sensor achieve extremely low-noise image quality.
Sonys CMOS-based sensor circuitry runs at lower voltage and consumes less power than conventional CCD-based processors, resulting in longer battery life, smaller batteries, & smaller cameras.
