Cutting-edge Imaging System for New Camcorder
1. 1/3 Inch-type 3 ClearVid CMOS
Sensor System
The 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 the 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, this 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 because it can always produce maximum
resolution, regardless of the balance between color
elements, thanks to its unique and sophisticated
interpolation technology.
2. Enhanced Functionality with the
Technology of Exmor
The new HVR-Z5U boasts cutting-edge features
such as the technology of Exmor, which utilizes the
full potential of the 3 ClearVid CMOS Sensor
system. Exmor features the column-parallel A/D
conversion technique and the dual noise-
cancelling method also used in Sony’s top-of-the-
line models. 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-type 3 ClearVid CMOS Sensor system
enables the HVR-Z5U to achieve a low light
sensitivity of just 1.5 lux*
