GPixel Unveils Full-Frame Sensors for High End Photography and Video

Gpixel announces GCINE4349, a first product in the new GCINE product series based on BSI stacked image sensor technology for cinematography, drones, production imaging and other video applications. The GCINE product line features BSI for high QE and good angular response, as well as wafer stacking with exposure summing for HDR modes up to 110 dB (18+ f-stops) and 8K frame rates up to 120 fps.

GCINE4349, the first new product of this family, is a 49MP (35.2 x 25.8 mm) full frame image sensor with a 4.3 μm^2 BSI pixels supporting 8K or binned 4K video with maximum frame rates of up to 120 fps at 8K resolution and up to 240 fps at binned 4K resolutions, all with a pixel bit depth of up to 16 bit/pixel interfaced over 64 sub LVDS channels @ 1.2 Gbps/channel. In full frame you can use the full width of the sensor (8192 pixel) for 8K DCI widescreen, 2.4:1 8K wide or scope format, 8K open gate and various other creative imaging formats.

GCINE4349 is developed using a 2-wafer level stacked BSI architecture. The top layer consists of a BSI pixel array with 49M 4.3 um pixels achieving a maximum QE of up to 75% at 525 nm. The bottom digital CMOS layer consists of an array of core cells each including 16-bit ADC blocks and SRAM memory blocks which are used to sum and store up to 4 subsequent sub-frames with seamless exposure, enabling an in-pixel full well charge of up to 160k e- for a dynamic range of 80 dB.

The GCINE4349 architecture also supports two additional HDR modes. Firstly, a proprietary Variable Slope High Dynamic Range method achieving an exceptionally high 110 dB of Dynamic Range. Secondly, a classic dual gain read out achieving up to 87 dB of Dynamic Range. An additional DSC mode can be enabled for low noise read out down to 1.7 e- and dedicated shutter control for DSC operation.

GCINE4349 is packaged in a 431-pin LGA ceramic package and comes with a double side AR coated glass lid.

Gpixel plans to expand the GCINE sensor series and offer a broad portfolio of products suitable for high-end video and photography.
