New Full-Body 49MP Sensor Can Shoot 8K at 120FPS, 4K at 240FPS


Gpixel GCINE4349

Sensors are the primary battleground within the digicam business, and Gpixel’s newest seems to be properly conscious of that truth. The corporate has created a 49-megapixel, HDR, backside-illuminated, stacked sensor able to as much as 8K at 120 frames per second.

Gpixel has been producing sensors for the safety and industrial functions house since 2012, however within the final 12 months it has produced not less than three sensors that look extraordinarily promising for the patron imaging house. In August, the corporate stated it had developed a brand new international shutter 4/3-inch 10-megapixel sensor that it claims will probably be able to capturing 4K video at as much as 2,000 frames per second. In September, it launched what it billed because the world’s highest-resolution international shutter sensor: 152-megapixels.

Extra not too long ago, Gpixel introduced what it calls a next-generation sensor: a full-frame, backside-illuminated (BSI), stacked sensor designed particularly for images and cinematography. Whereas not a world shutter design, that’s nonetheless an impressive-looking sensor.

The GCINE4349 is the primary in what Gpixel says will probably be a flagship household of sensors and incorporates a 49-megapixel (35.2 x 25.8 mm) full-frame picture sensor with 4.3 μm2 BSI pixels. It has a most decision of 8,192 by 6,000 pixels and a number of other readout modes that may help 8K or binned 4K with most body charges of as much as 120 frames per second at 8K decision and as much as 240 frames per second at binned 4K resolutions, all with a pixel bit depth of as much as 16 bit/pixel interfaced over 64 sub LVDS channels at 1.2 Gbps/channel.

In full-frame, Gpixel says the sensor offers full 8K DCI widescreen (8,192 pixels), but in addition helps 2.4:1 8K extensive or scope format, 8K open gate, and numerous different artistic imaging codecs. The native 8K decision at its 3:2 side ratio permits filmmakers to shoot oversampled in a method that ideally matches a completed 6K or 4K movie.

“GCINE4349 is developed utilizing a two-wafer stage stacked BSI structure. The highest layer consists of a BSI pixel array with 49M 4.3 um pixels attaining a most QE of as much as 75% at 525 nm. The underside digital CMOS layer consists of an array of core cells every together with 16-bit ADC blocks and SRAM reminiscence blocks that are used to sum and retailer as much as 4 subsequent sub-frames with seamless publicity, enabling an in-pixel full properly cost of as much as 160k e- for a dynamic vary of 80 dB,” Gpixel explains.

The structure permits for 2 HDR modes that Gpixel says permits it to realize wonderful picture high quality in quite a lot of lighting situations. The primary is a proprietary “Variable Slope Excessive Dynamic Vary” methodology that the corporate says lets the sensor obtain 110 dB of dynamic vary (what it says is “exceptionally excessive”). The second is a basic twin achieve learn out that achieves as much as 87 dB of dynamic vary. Gpixel additionally has a devoted nonetheless digicam mode with low noise readout and a devoted shutter controller.

Gpixel’s GCINE4349 appears, on paper, to be one of many extra spectacular high-resolution, low noise sensors to be developed, but it surely’s unclear who the corporate intends to promote its product to. Sony and Canon make their very own sensors, and Nikon usually works with Sony to supply the sensors in its cameras. Nonetheless, hopefully, Gpixel’s continued funding within the house will end in continued good points in efficiency, and even perhaps extra spectacular capabilities are to return to the subsequent era of cameras.
