ABSTRACT

    Techniques are provided for enlarging shared content during a web conference or other video conference setting in such as manner so as to avoid missing any important information.

DETAILED DESCRIPTION

     Sharing (desktop sharing, application sharing etc.) in a web conference meeting is an important feature. It improves communication and collaboration. However, with many users choosing to participate in web conference meetings with mobile devices, a small screen user has to endure poor user experience.

    It has been discovered that the active region in a sharing session is not always properly detected and conveyed to other participates. The active region should be considered as multiple active regions. This is illustrated in Figure 1 below.

device user. S/he can choose to enlarge one active region, but in so doing, s/he could lose content in other active regions.

    Presented herein are techniques designed to track multiple active regions simultaneously. These techniques allow for enlarging multiple active regions but keep them on one screen. This allows a mobile device user to enlarge content but not miss important information.

Figures 3-5 demonstrate the entire process.

In the original image (Figure 3), the red box regions (Figure 4) are active regions.

After enlarging, the result is as shown in Figure 5.

between the "important part" (active regions) and "whole content" (in one screen). Simultaneously, some unimportant information is removed. This improves user experience.

    Implementation of this idea is described with respect to an example. Assuming the original image size is W/H. When displaying on small screen device, such as a mobile phone, the image size changes to Wm/Hm. The width-height ratio is the same between W/H and Wm/Hm.

    When a user enlarges the content on a mobile device, assuming the destination size is 1.2Wm/1.2Hm, in the previous method, the content will be enlarged to this size and edge parts will be cut/cropped.

    However, in this method an image processing is performed to convert content from 1.2Wm/1.2Hm to Wm/Hm. After that processing, the weakest 0.2Wm/0.2Hm information is removed. This removed part is not always equal to the edge...
