Toshiba on Friday launched the T4K35, a 1.12µm, 8-megapixel BSI CMOS image sensor with color noise reduction (CNR) designed for cell phones, smartphones and tablets.
The product integrates a CNR circuit and realizes a signal-to-noise ratio equal to Toshiba’s equivalent products fabricated with 1.4µm pixel process.
The "T4K35" also incorporates a high dynamic range (HDR) function that faithfully reproduces dark and bright areas in high contrast images. A frame rate of 30fps at full resolution reduces delays in imaging, resulting in less release time lag, and allows continuous shooting.
The CMOS image sensor will enter mass production on November 15, Toshiba said.
