Inventor: KOSEKI MASARU
IPC: H04N5/378
Filed: 2002-04-04
Abstract: <P>PROBLEM TO BE SOLVED: To realize an FPN (Fixed Pattern Noise) suppression function with excellent amplification factor and linearity and a simple configuration in the case of using an imaging device of a current output type.  <P>SOLUTION: An Nch MOS transistor at an input side of a current mirror 70 is functioned as a voltage operating point setting section to always stabilize a level of a pixel signal (a voltage of a horizontal signal line 20) around a GND level. Thus, the amplification factor and the linearity of an amplification transistor in a solid-state image pickup device 3 are improved. A current copier 90 is functioned as a current sampling section, receives a signal current IIN of the solid-state imaging device 3 via a current mirror 70, and samples the pixel signal for a reset period as without modifying a current component. An offset component included in the pixel signal is eliminated by obtaining a difference between the current component for the detection period and the offset current being a current component sampled for the reset period, only a pure signal I<SB>sig</SB>is extracted at an output terminal IOUT to realize the FPN suppression function.  <P>COPYRIGHT: (C)2004,JPO
