Toshiba Expands Range of PDAF-equipped CMOS Image Sensors
Toshiba has expanded its range of backside illumination (BSI) CMOS image sensors equipped with Phase Detection Auto-Focus (PDAF). The range expansion features the 8MP T4KA3-121, the 16MP T4KC3-121, the 13MP T4KB3-121 and the 20MP T4KA7-121.
Originally developed for SLR cameras, PDAF locks in focus at speeds much faster than the autofocus systems currently used in smartphones and tablets – making it easier for mobile devices to capture not only the still objects, but also fast moving objects.
Toshiba’s Bright Mode technology increases image brightness by 4 times and these sensors also support HDR capture.
The T4KA3-121 offers output speeds of up to 30fps at full 8MP resolution with power consumption figures of just 140mW or lower. Full-HD outputs are supported at frame rates of up to 60fps, and HD outputs are supported at 120fps in normal mode and 240fps in Bright Mode.
The T4KB3-121 and T4KC3-121 achieve output speeds of up to 30fps at 4K2K resolutions, Full-HD at frame rates of up to 60fps, and HD outputs at 120fps.
The T4KA7-121 achieves output speeds of up to 22ps at full 20MP-resolution 24fps at 18.8MP and 28fps at 16.3MP, with a power consumption of 440mW.Tags: Phase-Detection Auto-Focus, Toshiba, Backside illumination, BSI CMOS image sensors, Autofocus systems, Toshiba’s Bright Mode technology
