CMOS Image Sensors feature Bright Mode technology.
January 13, 2014 -
With Bright Mode CMOS Image Sensor technology, smartphones and tablet PCs can record Full-HD video at 240 fps. Additionally, Bright Mode realizes quality, slow motion video playback at 1/8 standard speed. Technology doubles exposures time by adopting interlaced video output. It also employs charge binning, which doubles electrical charge of each pixel, resulting in images that are 4x brighter than those from CMOS image sensors without Bright Mode.

Toshiba Announces Bright Mode High-Speed Movie Technology for CMOS Image Sensors in Smartphones and Tablets
Bright Mode Enables 240 fps Equivalent High-Speed, Full-HD Movie Capture
LAS VEGAS, -- CONSUMER ELECTRONICS SHOW (CES) -- Toshiba America Electronic Components, Inc. (TAEC)*, a committed leader that collaborates with technology companies to create breakthrough designs, today announces its Bright Mode technology. The Bright Mode CMOS image sensor technology allows smartphones and tablet PCs to record Full-HD video at 240 frames per second (fps), the industry's highest frame rate(1). Additionally, Bright Mode realizes high quality, slow motion video playback at one-eighth the standard speed(2 )offering new dimensions in camera imaging during high-speed video.
"Bright Mode technology continues the Toshiba track record of delivering best-in-class image quality through continuous innovation," says Andrew Burt, vice president of the Image Sensor Business Unit, System LSI Group at TAEC. "Bright Mode technology contributes to a wide variety of movie applications, such as high-speed recording, slow-motion movie, and fast-action cameras. It improves video viewing, especially in slow motion, which is timely given the explosion of mobile applications where the exchange of short movie clips is gaining in popularity."
High-speed video recording requires a high-frame rate with short exposure time, which results in under exposed images. Bright Mode technology doubles the exposure time by adopting interlaced(3) video output, not the progressive(4) output that standard CMOS sensors use. Bright Mode also employs charge binning(5), which doubles the electrical charge of each pixel, resulting in an image four times brighter than that from a CMOS sensor without Bright Mode. 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.
Sample sensors incorporating Bright Mode will be available in Q1 2014.
