HDR-Like Imaging

Improving image quality by expanding the dynamic range has been intensively used recently. This results in the presence of much more details in the image, which is very important in most applications. The spread of the dynamic range has its limits and they are defined by the physical limits of the sensor used, i.e. the limitations of its A/D converter. When the dynamic range of the scene is significantly wider than the dynamic range of the sensor, many details will not be adequately displayed in the image. However, situation is significantly different if a used sensor inherently supports a wide dynamic range. Expanding the dynamic range of the image itself introduces using a new image format that is intended to store more information about each pixel in the image. Image or video content in this format can be integrated into existing systems, but the solution can be very expensive. Special attention is devoted to the presentation of HDR and HDR-like technology. Finally, the forming of HDR-like images and the results are presented.
