摘要： An NchMOS transistor Q71 on the input side of a current mirror 70 is made function as a voltage operating-point setting portion so that a pixel signal line potential (voltage of a horizontal signal line 20) would be constantly stable nearly at the GND. Then, an amplification factor and linearity become good in an amplification transistor in the solid imaging device 3. A current copier 90 is made function as a current sampling portion so as to receive a signal current IIN of the solid imaging device 3 through the current mirror 70 to carry out sampling of a pixel signal in a resetting period in the shape of current component as the pixel signal is. Calculating differential between a current component in a detecting period and an offset current, which is the current component in a resetting period in sampling, allows an offset component included in the pixel signal to be removed and only pure signal Isig to be picked up at an output terminal Iout, so that the FPN restraining function can be fulfilled.

摘要： From a pixel array where imaging pixels are arranged, pixel signals of respective columns on a selected row are read in parallel in a horizontal blanking period of a horizontal period. The pixel signals of the respective columns are output to horizontal signal lines in an effective period of the horizontal period via charge integrating amps provided respectively for the columns, i.e., provided respectively for vertical signal lines, and are thereby transferred horizontally. In the charge integrating amps, it is possible to enter a standby state while holding the pixel signals by a holding voltage. Furthermore, in the charge integrating amps, a reference potential for precharging feedback capacitors for amps at the time of a reading operation is automatically controlled based on a black level. Furthermore, pixel signals from the respective charge integrating amps are horizontally transferred in parallel using a plurality of horizontal signal lines.

摘要： A solid-state image pickup apparatus and an image pickup method are disclosed which can detect and correct fixed pattern noise efficiently and accurately. Pickup image signals produced by reading out signals in parallel from a pixel sensor section are subject to an analog gain process, an A/D conversion process and a digital gain process. Within a period within which the pickup image signals which are based on a fixed value are inputted within a one-frame period, a reference signal average is produced from the signals. Sum values of difference values of the signals from the reference signal average are stored. Within a period within which the pickup image signals from valid pixels are inputted within the one-frame period, fixed pattern noise is removed from the pickup image signals using division averages obtained by dividing the stored sum values.

摘要： An imaging apparatus includes a solid-state imaging device that outputs a captured image signal in current mode, which in turn is subjected to CDS processing in current mode by a current signal detector, thus suppressing FPN noise. A captured image signal output by the current signal detector is amplified by a programmable gain amplifier to a certain level, and the amplified signal is converted by a current-to-voltage transducer into a voltage signal. In a clamp circuit including a current-output differential amplifier and a current adder, the differential amplifier compares the voltage signal with a reference voltage from a reference voltage source and feeds back a clamp current to the current adder so that the difference between the voltage signal and the reference voltage becomes substantially zero. The current adder is required to simply add a signal current and the clamp current.
