Toshiba today announced the development of
"Bright Mode", a CMOS image sensor technology that allows
smartphones and tablets to record Full HD video at 240 frames
per second (fps).
High speed video recording requires a high frame
rate with short exposure time, which results in underexposed
images. "Bright Mode" technology secures double the exposure
time by adopting interlaced video output, not the progressive
output that standard CMOS sensors use. "Bright Mode" also
employs charge binning, which doubles the electrical charge of
each pixel, resulting in an image four times brighter than that
from a CMOS sensor without "Bright Mode". The technology also
realizes 240 fps equivalent Full HD video recording.
Toshiba will also provide an interlace-progressive conversion
program that enables users to offer high quality progressive
video with low deterioration, without changing frame rate.
In addition, CMOS image sensors incorporating "Bright Mode" can
playback high quality video in slow motion at one-eighth
standard speed, bringing new dimensions to imaging.
Toshiba's will start offering sample sensors incorporating
"Bright Mode" in Q1 2014.
