Abstract: 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.

Abstract: A method controls access permission to an image including receiving session information from a first camera at a first position, the session information indicating a subject to be photographed and a session in which the first camera joins, receiving an image of the subject from the first camera, updating the session information such that a second camera, at a second position, joins the session, and monitoring whether the second camera joins the session. A first period is calculated in which the second camera joins the session, a second period is calculated based on the first period, and access permission to a shared image is controlled such that the second camera downloads the shared image during the second period and does not download the shared image outside of the second period, the shared image being one of the image and an image generated based on the image.
