| description | This work investigate the problem of the process of preparing high-dynamic range images (HDR-image) for hosting on websites. The proper functioning of websites it is necessary to take into account the effect of the large volume of HDR-image information. Therefore, the result of present research work will allow to determine the rational values of visual quality and file size of digital images, as well as to enhance the functionality of websites with HDR-image.
According to the analysis of the previous research works of the technologies for the creation of HDR-photographs was determined of perspective directions of HDR-technologies: development of new effective image processing schemes, the creation of sensors in cameras with increased photosensitivity and the improvement of the devices design for the creation of HDR images.
It was proposed the algorithm for the preparation of HDR-image with main steps: setting the camera and selecting rational modes (aperture, shutter speed and light sensitivity); preparation of the function of automatic change of exposure modes; receiving a series of RAW-images with different exposure indicators; the process of creating HDR-images using the Adobe Camera RAW utility.
The Nikon D5100 camera and various photographic modes was used for capture RAW photos with various features (range of exposure compensation, exposure steps, and image compression). The evaluation of the relative quality index (the average value of contrast in 12 local gradation photo areas) was used to creating HDR-photos.
According to the results of the research, the influence of the main modes and parameters of the process of creating images with an expanded dynamic range on the functionality of the site was established. The main recommendations for improving the websites functionality was developed. |
