<P>PROBLEM TO BE SOLVED: To provide a light source detection sensor capable of easily discriminating a blue flood lamp from a flood lamp, and a camera using the sensor. <P>SOLUTION: This sensor includes a visible light sensor for detecting light via an IR cut filter 2, an infrared light sensor for detecting light via a visible light cut filter 4, a blue light sensor for detecting light via a blue filter 3 for allowing transmission of only a component corresponding to blue from the light via the IR cut filter, and a light source determination part 100 for determining a light source. The light source determination part is constituted to determine the light source based on the ratio between a component of visible light and a component of infrared light, and on the ratio between the component of visible light and a component of blue light. <P>COPYRIGHT: (C)2010,JPO&INPIT |
