With more than 83dB DR, 1/50,000 shutter efficiency and wide angular response, the GMAX4651 is aimed to advanced optical inspection and machine vision applications (Automated Optical Inspection (AOI) and Flat Panel Display (FPD) inspection) as well as high-end 8k/4k video broadcast and aerial imaging applications.
“The GMAX4651 is a really unique addition to our GMAX series, outperforming existing CCD solutions on all performance levels,” commented Wim Wuyts, Chief Commercial Officer of Gpixel. “It combines the dual gain HDR used in our successful GSENSE sensors, with excellent global shutter pixel technology and unprecedented frame rates. All together this will set a new industry standard for high-end industrial inspection and the video industry.”
Based on a 4.6 µm charge domain global shutter technology with true CDS, the GMAX4651 delivers more than 25 ke- linear FWC and up to 50 ke- when using 1x2 binning and ultra-low noise read out down to 1.5 e-RMS. Under dual gain HDR mode, where the sensor reads out the same exposure with two different gain settings for off-chip HDR reconstruction, DR can reach 83dB.
GMAX4651 mono sensor sample and evaluation kit will be commercially available in March 2019. Color samples will be made available in Q2 2019 and volume production is targeted for Q3 2019.
Really impressive. However the fact of acquire an HDR image with two separated linear images with different exposure time and external reconstruction is fully trivial and I don't understand why the HDRZ is limited up to 83dB.
ReplyDeleteIn fact, a single image at full frame should be able to have a DR or more than 83dB in linear mode.
Something is wrong in the announcement.
The HDR is done actually with a single exposure but sampled twice with different DN/e gain. This is the principle Gpixel always use I believe. The halved fps is because two images have to be produced.
