Apparent magnitude is the brightness of an object as it appears to an observer onEarth. TheSun’sapparent magnitude is −26.7, that of the fullMoonis about −11, and that of the bright starSirius, −1.5. The faintest objects visible through theHubble Space Telescopeare of (approximately...

The device includes a brightness controller configured to selectively control a brightness controlling range based at least in part on the magnitude of the video data input in one frame, and a gamma correcting unit configured to control the portion of maximum luminance corresponding to full scale ...
powder, which has a general formula (Y1-p-q-rGdpCeqSmr)3(Al1-sGas)5O12, where 0≦p≦0.8, 0.003≦q≦0.2, 0.003≦r≦0.08, 0≦s≦1. The blue LED irradiates a fluorescent material to general yellowish light that is complementary to the blue light. The blue light and the yellowish ...
The data normalization process is to convert all data into data between 0 and 1, which is to eliminate the order of magnitude difference of data of various dimensions and avoid large network prediction errors caused by a large order of magnitude difference in input data. The data normalization ...
