  1. 6. Strobed IR Illumination for Image Quality Improvement in Surveillance Cameras

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Steve Darmadi; [2018]
    Keywords : surveillance camera; infrared; strobing; rolling shutter; license plate recognition; övervakningskamera; infraröd; strobing; rullande slutare; registreringsskyltigenkänning;

    Abstract : Infrared (IR) illumination is commonly found in a surveillance camera to improve night-time recording quality. However, the limited available power from Power over Ethernet (PoE) connection in networkenabled cameras restricts the possibilities of increasing image quality by allocating more power to the illumination system.

  3. 7. Ionizing Radiation Effects on Image Sensors: Method on Evaluation from an Image Quality Perspective

    University essay from Lunds universitet/Högskoleingenjörsutbildning i datateknik

    Author : Johan Fagerström; [2016]
    Keywords : image sensor; cmos; ov7949; electronic camera; radiation effects; ionizing radiation; image quality assessment; radiation tolerance; Technology and Engineering;

    Abstract : Surveillance cameras are vital in the nuclear power industry where the reactor equipment must constantly be kept under surveillance to maintain safety. Constant monitoring is however difficult due to the highly radioactive environment, which cause cameras to malfunction and eventually break. READ MORE

  4. 8. A Cyclic Analog to Digital Converter for CMOS image sensors

    University essay from Elektroniksystem; Tekniska högskolan

    Author : Deyan Levski Dimitrov; [2014]
    Keywords : CMOS; Image Sensor; ADC; Cyclic ADC; Algorithmic ADC; MDAC; Switched Capacitor; Comparator; OTA; Logic; IC; VLSI; Circuit; System;

    Abstract : The constant strive for improvement of digital video capturing speeds together with power efficiency increase, has lead to tremendous research activities in the image sensor readout field during the past decade. The improvement of lithography and solid-state technologies provide the possibility of manufacturing higher resolution image sensors. READ MORE

  5. 9. Full frame 3D snapshot : Possibilities and limitations of 3D image acquisition without scanning

    University essay from Institutionen för systemteknik

    Author : Björn Möller; [2005]
    Keywords : Datorteknik; Snapshot 3D imaging; depth measurement; triangulation; interferometry; time-of-flight; CMOS image sensors; Datorteknik;

    Abstract : An investigation was initiated, targeting snapshot 3D image sensors, with the objective to match the speed and resolution of a scanning sheet-of-light system, without using a scanning motion. The goal was a system capable of acquiring 25 snapshot images per second from a quadratic scene with a side from 50 mm to 1000 mm, sampled in 512×512 height measurement points, and with a depth resolution of 1 µm and beyond.
