Method and apparatus for maintaining a minimum pixel density across an object of interest

Apparatus for maintaining a minimum pixel density across an object of interest, the apparatus comprising:

• an interface configured to receive a frame of video, wherein the received frame contains an object of interest and receive an indication of available throughput of a wireless network used for transmitting the video to a viewing device;
• a processing device configured to:
• determine a current pixel density of the object of interest within the received frame;
• compare the current pixel density to a minimum pixel density for the object of interest to generate a comparison result;
• select a pixel density compensation method from a plurality of pixel density compensation methods used to adjust the current pixel density, wherein the selecting is based on the comparison result and the indication of available throughput, wherein the plurality of pixel density compensation methods comprises a first method of adjusting a zoom feature of a camera used to capture the video and a second method of adjusting encoded frame resolution for at least one of the camera or an encoder used to encode the video for transmission to the viewing device over the wireless network;
• determine, using the selected pixel density compensation method, a pixel density compensation parameter to adjust the current pixel density with respect to the minimum pixel density for the object of interest;
• wherein the interface is further configured to provide the pixel density compensation parameter to at least one of the camera or the encoder.
