Super Dynamic Range of 65dB

SANYO’s Advanced WDR camera has achieved super dynamic range of 65dB in the industry top class by combining with the new WDR CMOS sensor and SANYO’s Advanced Image Processing Engine. (Advanced WDR Image Processing System)

550 TV Lines of Horizontal Resolution Ensure High-Definition Images

The camera is equipped with a new 1/3-inch CMOS sensor and newly developed SANYO Advanced Image Processing Engine to provide maximum information density. The result is a 480,000 pixels resolution with images having the industry’s top-ranking level 550 TV lines of horizontal resolution.

CMOS Sensor of Super Dynamic Range

Conventional CCD drawbacks included electrons that overloaded when receiving too many electrons and allowed signals to leak. This in turn reduced the device’s dynamic range. The newly developed CMOS sensor is engineered to handle leaked electrons and can transmit virtually complete receiving image information to image signals, effectively reproducing images having a wider dynamic range for clearer images that reveal more. The new CMOS sensor features an extremely wide dynamic range that far surpasses conventional cameras.

Progressive Scan System

In a conventional CCD, an image is produced by using high-intensity and low-intensity signals to obtain dynamic range, and this generates time lag. A progressive scan system eliminates image composition processing, preventing time lag from being generated and delivering a high-quality clear image without misaligned contours from the composition process even if capturing a quick-moving subject.

“Retina-Morphic Processing Algorithm”

The newly developed “SANYO Advanced Image Processing Engine” utilizes a “retina-morphic processing algorithm” for effective real-time dynamic range correction. Processing is with an algorithm developed after extensive research into the human optic system including eyes, the optic nerve and brain. Utilizing a model of the human retina’s dynamic range adjustment ability, this algorithm provides revolutionary corrective effects that set a new reference standard. Every pixel has its luminance dynamically changed in reference to areas inside the frame. Images can therefore be realistically repro- duced even when luminance varies dramatically. Color reproduction under backlit conditions is optimized.
