LIGHT SOURCE POSITION DETECTION DEVICE, LIGHT SOURCE TRACKING DEVICE, CONTROL METHOD, AND PROGRAM |
摘要 |
A light source position detection apparatus (10) has a condensing lens (32) that condenses light emitted from the sun, an image pickup device (33) that receives the light condensed by the condensing lens (32), and a CPU (21) that detects the position of the sun based on per-pixel light reception information received by the image pickup device (33), and the CPU (21) changes the shutter speed of the image pickup device (33) and adjusts the quantity of the light received by the image pickup device in response to the quantity of light emitted from the sun. The light source position detection apparatus (10) can detect the position of a light source with high accuracy, and can detect the position of the light source with high accuracy even when the light source is hidden behind clouds, for example. |
