Proposed for the first time is a novel calibration empowered minimalistic multi-exposure image processing technique using measured sensor pixel voltage output and exposure time factor limits for robust camera linear dynamic range extension. The technique exploits the best linear response region of an overall nonlinear response image sensor to robustly recover via minimal count multi-exposure image fusion, the true and precise scaled High Dynamic Range (HDR) irradiance map. CMOS sensor-based experiments using a measured Low Dynamic Range (LDR) 44 dB linear region for the technique with a minimum of 2 multi-exposure images provides robust recovery of 78 dB HDR low contrast highly calibrated test targets.

Ccd Image

In this paper we present a CCD image sensor system with high dynamic range. This feature is achieved through double analog-to-digital convertors’(ADC) architecture and field programmable gate arrays(FPGA). By doing so, the system outputs high dynamic range images in real time. The proposed scheme is a low-cost solution in the sense that it can be built on top of any traditional sensor system with minor modifications on the system-level analog-to-digital module. Through the post-layout sensor system we show the experimental images to demonstrate the effectiveness.

This paper presents a prototype linear response single exposure CMOS image sensor with two-stage lateral overflow integration trench capacitors (LOFITreCs) exhibiting over 120dB dynamic range with 11.4Me- full well capacity (FWC) and maximum signal-to-noise ratio (SNR) of 70dB. The measured SNR at all switching points were over 35dB thanks to the proposed two-stage LOFITreCs.
