摘要： A differential amplifier has a first input terminal to which a voltage of a noise signal of the solid-state imaging device is supplied and a second input terminal to which a voltage of a temporary data signal having the noise signal of the solid-state imaging device superposed thereon is supplied. The differential amplifier inverts an output signal when a magnitude relationship in voltage between the first and second input terminals becomes reverse. A measurement circuit measures a variation amount of a voltage of the second input terminal from when the voltage of the second input terminal begins to vary in a direction to reverse the magnitude relationship to when the output signal of the differential amplifier is inverted, and outputs a measurement result as a digital value indicating a voltage of a real data signal obtained by removing the noise signal from the temporary data signal.

摘要： A solid-state image pickup device and image pickup method eliminate a dark-current component by adjusting the black level appropriately even if the dark-current component varies among horizontal lines. A pixel array includes light-receiving pixel elements and light-blocking pixel elements disposed such that horizontal lines include the light-blocking pixel elements individually. A readout circuit block reads pixel signals of each of the horizontal lines from the pixel array, inputs the pixel signals to ADC circuits (column ADC circuit block), and outputs the pixel signals of the light-blocking pixel elements. A ramp signal generation circuit obtains the pixel signals of the light-blocking pixel elements output from the readout circuit block, generates a ramp signal by using a reference level of AD conversion adjusted for each of the horizontal lines in accordance with the obtained pixel signals of the light-blocking pixel elements, and inputs the ramp signal to the ADC circuits.

摘要： The challenge of the present invention is to suppress a variation in brightness of an image and make a reference value of a black level converge at an appropriate value in a short time. Acondition judgment circuit judges whether or not a frame of an amount of change in gains of a variable gain amplifier being equal to or greater than a threshold continues for a predefined frames or more. If a frame of an amount of change in the gains being equal to or greater than the threshold continues for the predefined frames, a black level value of the current frame is set for new black level reference. If not continues for the predetermined number, the previous black level reference value is retained in lieu of correcting the black level.
