Image Sensor Simulator Upgrade
First, we would like to thank everyone who has given us feedback about our image sensor simulator. Based on the feedback we have added couple new features to it, i.e. Point Spread Function (PSF) to simulate cross-talk and pixel size which is now decoupled from light intensity and dark current settings. Cross-talk can be divided Read the Rest…
Modified Internal Gate (MIG) Technology in Security and Surveillance Applications
Updated Sep 26, 2012 In security and surveillance applications identifications is often done from a stored video stream. Especially in the low light outdoor applications the signal-to-noise ratio in single video frames is often too low for identification. However, one can look after periods in the stored video stream when the subject remains more or Read the Rest…
Difference between MIG and IG
There is often confusion about how Modified Internal Gate (MIG) technology differentiates from Internal Gate (IG) technology. We prepared a video presentation about the two technologies where we present the challenges found in IG imagers and how MIG imagers overcome them. The video is targeted to technical audience — enjoy! Please don’t hesitate Read the Rest…
Charge Transfer in Double MIG Pixel
The Non-Destructive Correlated Double Sampling (NDCDS) is enabled by the ability to transfer signal charge continuously between two MIGs. Below is a video which demonstrates how charge can be transferred in a basic double MIG pixel. Both simulation and measurement results are shown. The measurement is taken from a single pixel test structure which don’t Read the Rest…
1T MIG Pixel
We think that future image sensor pixels should be more simple and elegant and that they should offer better performance than is possible today. The present 4T CMOS pixel has been pushed towards its limits and yet the image quality should be improved. New approaches are needed to overcome the challenges in today’s technologies. Please Read the Rest…
Nokia 808 PureView Camera – Yes There is Also a Phone Feature
Nokia’s new PureView Pro imaging technology was announced today at Mobile World Congress. The first phone including this technology is Nokia 808 PureView which has pretty amazing camera specs, Carl Zeiss optics, 41 MP sensor with 1.4 micron pixel size (White paper here). There has been some debate whether or not anyone needs 41 MP Read the Rest…
Image Sensor Simulator
There are multiple low light applications that need or benefit from multiple readouts taken during a long exposure time. With present destructive CDS readout technology, sampling multiple times means that the read noise increases compared to a single exposure image. With Pixpolar’s non-destructive CDS readout it is finally possible to sample as often as needed Read the Rest…
Lytro is Shaking the Camera Industry
Until recently, light field imaging has been performed with systems including several large cameras and a supercomputer. Yesterday, Lytro presented a first consumer level light field camera which will certainly shake the whole camera industry. Pictures taken with conventional cameras are two dimensional light intensity maps. Light field pictures include also information of the directions Read the Rest…
