This thesis presents an overview of an automated system for measuring various camera timings, such as exposure time, rolling shutter time and shutter lag. Comprehension of these timings as well as the ability to rely on them are crucial for professional photography, since they have a significant effect on the image quality. In order to characterize the timings, it is possible to perform measurements utilizing a specific setup, following the ISO standard 15781. The standard requires to use a certain type of a timer for the measurements. The DxO Timer is utilized for the current research, since it follows the standard and allows measuring the aforementioned timings. In addition, the DxO Timer can be used for measuring negative shutter lag, which is a common feature of modern cameras. The thesis describes the algorithm for automatic timing extraction from the setup and provides experimental verification of the proposed automation.
