摘要: In a converting method relating to picture luminance according to one aspect of the present disclosure, the picture luminance is formed by luminance values in a first luminance range. In this method, a first luminance signal that indicates code values obtained by quantizing the luminance value of the picture is obtained, code values, which are associated with the code values indicated by the obtained first luminance signal by quantization for a second luminance range different in a maximum value from the first luminance range are determined as converted code values, and the first luminance signal is converted into a second luminance signal indicating the converted code values. As a result, the converting method is further improved.

摘要: Systems, methods, and modes are disclosed for live presentation sharing between meeting presenter's and meeting attendees' portable electronic devices during a meeting, and more specifically for viewing presentation content on a portable electronic device displayed on a meeting room display during a meeting. The system comprises a presentation gateway configured for receiving and transmitting presentation content to a meeting room display during a meeting. The system further comprises a portable electronic device that pairs with the presentation gateway. The presentation content is displayed on the portable electronic device substantially in synch with the presentation content displayed on a meeting room display by repeatedly capturing a new image from the presentation content, comparing each new image to a previously saved image to determine whether the new image is substantially identical to the previously saved image, and saving a new image that is not substantially identical to the previously saved image, wherein the newly saved image is displayed on the display of the portable communication device.
