Cutting-edge imaging System for New Camcorders

✜1/3 inch-type 3 ClearVid CMOS Sensor system

The newly developed 1/3-inch type 3 ClearVid™ CMOS Sensor system has 45-degree rotated pixels on each chip in order to increase the signal density, while each pixel maintains sufficient surface area.

In combination with Enhanced Imaging Processor™ (EIP), the 3 ClearVid CMOS Sensor system achieves high resolution, high sensitivity, wide dynamic range, and excellent color reproduction.

The pixel shift interpolation technique has been traditionally used in small 3CCD camcorders. However, it normally requires the combination of all three color element (RGB) signals to maximize resolution. If an object lacks one or more color elements, the resolution of the object may be degraded.

The 3 ClearVid CMOS Sensor system is different. It can always produce maximum resolution, regardless of the balance between color elements, thanks to its unique and sophisticated interpolation technology.

✜Enhanced Functionality via the Technology of Exmor

Both the HVR-Z7U and HVR-S270U offer cutting-edge features, such as the technology of Exmor™ developed by Sony, which utilizes the full potential of the 3 ClearVid CMOS Sensor system.

The technology of Exmor, which features the column-parallel A/D conversion technique and the dual noise cancelling method are also used in other camera products from Sony.

Multiple A/D (analog to digital) converters on each pixel row convert analog signals to digital as soon as they are generated, unlike traditional technology that only has one A/D converter on each chip. The technology of Exmor can eliminate the influence of external noise that enters the signal chain during transfer to the A/D converter, resulting in high-quality digital signals with extremely low noise. This significantly enhances shooting in low-light environments.

By adopting this groundbreaking technology, the new 1/3-inch 3 ClearVid CMOS Sensor system enables the HVR-Z7U and HVR-S270U to achieve a low light sensitivity of just 1.5 lux*.
