HDR (high dynamic range) image capture using line-scan camera
Říha, Radim ; Richter, Miloslav (referee) ; Honec, Peter (advisor)
This bachelor’s thesis is focused on designing a system for controlling line scan cameras, which allows HDR image acquisition. The thesis first explains line scan cameras and the principle of HDR acquisition. Design of the control system and explanation of the individual signals and interfaces follows. Next the components are chosen, and the controller is designed as a microcontroller with additional circuitry, allowing for communication and control of other system blocks. Design, assembly, and evaluation of the controller PCB including the design of the box follows. The next part of the thesis explains the firmware, which was designed and tweaked during the hardware design stage. The application for controlling the system and image processing is designed next. In the final part, the whole system functionality is tested with a prototype of the lighting and the system is evaluated.

HDR Tone-Mapping
Vančura, Jan ; Mlích, Jozef (referee) ; Seeman, Michal (advisor)
This thesis concerns with the introduction to the problematics of images with high dynamic range (HDR) and possibilities of HDR images compression options for display on devices with a low dynamic range (LDR). In the introduction is described historical evolution of recording of reality. It is focusing towards point of view of physics, human visual perception and digital recording. There are described the ways of generating and holding of HDR images. The thesis is corncerned to the techniques of HDR compression, it means the tone-mapping. The different techniques of tone-mapping are explained and specific aproach is targeted to the gradient domain high dynamic range compresion.
