Wide dynamic range function3

Under adverse backlighting conditions, conventional cameras can not make

clear images. In this case, images in dark areas become almost black as

pitch and images in bright areas become almost white. JVC's new digital

signal processor (DSP) circuit, which enables the realization of a wide

dynamic range function, solves these problems. By capturing clear images

through the use of a low-speed shutter in dark areas and a high-speed

shutter in bright areas and then combining these two images, a uniformly

easy-to-view image can be achieved.

JVC's innovated technology featuring a

wide dynamic range function performs by

multi sampling method. TK-WD310U(B)

automatically adjust luminance by pixel

with 14-bit digital processing as well as

implement 5 level multi sampling, in order

to realize an accurate color reproduction.
