Transmission apparatus, non-transitory computer readable medium, and reception apparatus

A reception apparatus comprising:

• a communication interface configured to communicate with a transmission apparatus that acquires a depth image obtained by at least one depth camera measuring distances to a subject within a measurement range;
• and
• a controller configured to receive, from the transmission apparatus via the communication interface, a window identifier identifying a window corresponding to a position of the subject among a plurality of windows set within the measurement range and aligned in a depth direction, receive as pixel data, from the transmission apparatus via the communication interface, a converted value obtained by converting a measured distance into a relative distance within the window for each pixel of the depth image, identify the window corresponding to the received window identifier from among the plurality of windows, and restore the depth image by converting a relative distance within the identified window, indicated by the received pixel data, into a measured distance for each pixel of the depth image.
