Assessing daylight performance in use: A comparison between long-term daylight measurements and simulations

Climate-Based Daylight Modelling (CBDM) methods have been validated against long-term measurements in laboratory settings and found to exhibit errors small enough to make such assessments useful for daylight performance prediction. However, real occupied spaces are affected by a higher number of uncertainties than laboratory or controlled...

Adding Bloom to High-Dynamic-Range Tone Mapping

We present a technique for enhancing high-dynamic-range tone mapping algorithms by adding the bloom effect to bright areas. Bloom is based on the fact that real-life lenses convolve light and make bright areas emit a glow. The algorithm takes a set of images with different exposures as input, and performs a tone mapping algorithm on these. It...

A 1-Mega Pixels HDR and UV Sensitive Image Sensor With Interleaved 14-bit 64Ms/s SAR ADC

This thesis presents a 1-Mega pixels high-dynamic range and UV sensitive image sensor in 0.18 µm technology with 14-bit interleaved 64Ms/s SAR ADC. It can achieve 64 fps and 101 dB dynamic range. The pixel array contains three kinds of pixel: UV pixel, visible pixel and low blue pixel. Those three kinds of pixel form a special 4×4 kernel to meet...

The Design of a Stitched, High-dynamic Range CMOS Particle Sensor

This thesis presents the design of a stitched, high-dynamic range particle sensor in 0.18 µm technology, which has three different configurations of 4096*4096 (4K), 8192*8192 (8K) and 12288*12288 (12K) pixels. It can be operated at 65 MHz with a target of 5 e- RMS noise and 92 dB dynamic range. The architecture of the whole sensor is explained...

The Desigh of a High Dynamic Range CMOS Image Sensor in 110nm Technology

This thesis presents the design of a dual-transfer-gate high dynamic range CMOS image sensor. Several methods that can be applied to extend the dynamic range have been developed. However, all of these solutions have undesired problems, such as nonlinearity response, higher dark current shot noise and discontinues signal-to-noise ratio. In this...
