Increased Low Light Sensitivity & Boost

Double Scan CCD With
Conventional WDR

Single Scan CCD With WideLux WDR

WideLux offers +7dB boost in light sensitivity at all levels. Low Light Boost dramatically improves low-light scenes. Competing solutions depend on multi-frame integration (i.e. Sens-up), which results in motion smear and slow refresh. WideLux enables pixel binning of the sensor raw data, which boosts visibility in extremely dark situations. Detail normally lost during binning is reconstructed by the ISP, making images sharper.

Superior WDR at all contrast ratios

Normal WDR CCD

WideLux Controlled CCD

A normal WDR sensor has difficulty with low-contrast scenes. This non-linear characteristic prevents the conventional WDR solution from resolving shadow detail in many scenarios. WideLux balances the wide dynamic process, resolving detail under a wider range of lighting environments.

Increased Resolution

WideLux employs a special timing generator and operation to allow optimal vertical resolution from the Imager, as well as horizontal.

Color Rolling Suppression

Color Shift (ceiling and walls)

Color Shift (ceiling and walls)

WideLux (uniform ceiling and walls)

Fluorescent lighting can adversely affect color when a camera is in WDR mode. “Color Rolling” can occur as a result of asynchronous operation of the camera and the light. Color shift, changing tint and Shimmering edges are common. WideLux WDR technology uses adaptive timing to sync to fluorescent light. This virtually eliminates the color rolling effect!

Intelligent IR Control

Without

WideLux IR Control

When the objects come close to the IR light source, the objects become over exposed, crushing detail in conventional IR cameras. IR reflection is continuously tracked, and IR output is adjusted for proper exposure within 1 second. VHT has dramatically improved IR control performance with the latest design.

Extended IR LED Protection

Conventional IR assisted cameras operate LED’s at maximum brightness, requiring fewer LED’s. This design can easily overheat and shorten the lifespan. Visionhitech integrates special LED protection technology to regulate IR LED operation, which greatly extends performance and lifetime.
