AI Technical Summary

Benefits of technology

This patented describes methods for displaying videos alongside images based upon their qualities. It involves comparing each pair of pixels (called pixel) within two consecutive frames called segments), showing if they match up well enough together when displayed properly. If this happens, it suggests adding those areas around them instead of just giving everything downright. Additionally, some systems include displays with automatic adjustment capabilities by analyzing how many times certain parts of these scenes have been shown better than others during playback. Overall, these technical improvements help improve visual experience while playing back videos.

Problems solved by technology

This patented method involves complex steps involved with creation of videos by capturing scenes on digital cameras (DC). However this process can result in low-quality output due to imperfections like compression distortion caused during recording processes. Additionally it requires manual selection of good ones based solely upon visual inspection without any consideration given how well these choices affect overall viewers experience. Therefore automatic selecting optimal pictures has been proposed but existing solutions still lack efficiency and usability across different types of devices.

Embodiment Construction

(s)

[0023]FIG. 1 illustrates one embodiment of a system 100 in which aspects of the disclosed embodiments can be used. Although aspects of the disclosed embodiments will be described with reference to the embodiments shown in the drawings and described below, it should be understood that these aspects could be embodied in many alternate forms of embodiments. In addition, any suitable size, shape or type of elements or materials could be used.

[0024]The disclosed embodiments generally allow a user of a device or system, such as the system 100 shown in FIG. 1 to select one or more frames of a video sequence. The video sequence may be captured by the system or acquired by the system in any suitable manner. The disclosed embodiments select the highest quality frames (e.g. the sharpest and clearest frames) from a video sequence. In the disclosed embodiments a sharpness value is calculated for each frame of the video and a relative sharpness measure compares the sharpness between adjacent vide
