<P>PROBLEM TO BE SOLVED: To provide a technique for an imaging device improved in delayed response of photometry from the start of reception of light without using a light source for auxiliary lighting. <P>SOLUTION: The imaging device 1 includes: photoelectric conversion elements PD1-PD20 that generate photoelectric current by receiving the light from an object; a photometry circuit 50 having operational amplifiers OP1-OP20 that amplify the output based on the photoelectric current, and element groups EF1-EF2 that are connected between the input termini and output termini of each operational amplifiers OP1-OP20; and a current supply unit 30 that supplies auxiliary current to the element groups EF1-EF2 during the no-light period when the light from the object is not received at the photoelectric conversion elements. <P>COPYRIGHT: (C)2009,JPO&INPIT |
