High speed video recording requires a high frame rate with short exposure time, resulting in underexposed images. T4K82 incorporates "Bright Mode" technology that boosts imaged brightness up to four times. The sensor also adopts a newly developed low power circuit design that reduces power consumption to 82% that of T4K37, a 13MP/1.12um sensor in mass production. Although the full resolution mode speed is the same 30fps as its predecessor, the new sensor's video modes are much faster:
Other than interlaced to progressive conversion, the sensor features HDR and Color Noise Reduction (CNR) modes, lens shading correction, and many other functions:
Sample shipments are scheduled to start in March, with mass production to start in Sept 2014 with projected volume 2 million per month.
Why interlaced?
ReplyDeleteIn the interlaced mode, the exposure time can be doubled. you can refer this http://www.semicon.toshiba.co.jp/eng/profile/news/newsrelease/sensor/topics_140107_e_1.html
DeleteWhy interlaced?
ReplyDeleteBecause the progressive mode need double throughout. Therefore, for progressive mode the maximum frame rate will be 120fps instead of 240fps.
In addition, using interlaced scan allows you to double the exposure time - which is part of their so-called "bright mode".
