Abstract: A driving method is provided which enables a liquid feeding apparatus using a driving element in a membrane shape to feed a liquid at high liquid feeding accuracy. To this end, a voltage applied to the driving element is controlled in such a way as to repeat a first period in which the voltage is changed from a first voltage to a second voltage and a second period which is a longer period than the first period and in which the voltage is changed from the second voltage to the first voltage, and such that an inflection point is provided to each predetermined interval during the first period based on a Helmholtz vibration period unique to the liquid feeding apparatus.

Abstract: An image capturing apparatus is provided. The apparatus comprises an image sensor comprising pixels and a controller. The pixels include a photoelectric converter, a holding unit, an output unit and a first and second transfer unit. The controller causes the sensor to repeatedly perform a holding operation that the first transfer unit transfer charge from the photoelectric conversion unit to the holding unit, and a transfer operation that the second transfer unit transfer the charge from the holding unit to the output unit. The controller causes the sensor to perform, as the holding operation, holding operations including a first holding operation for performing the first transfer unit transfer charge generated in a first exposure time and a second holding operation for performing the first transfer unit transfer charge generated in a second exposure time longer than the first exposure time.

Abstract: Provided is a solid state imaging device including a plurality of pixels, a signal line on which a pixel signal is transmitted, a load transistor having a drain connected to the signal line, a readout circuit that reads out the pixel signal from the signal line, and a control unit that controls a current flowing in the load transistor in accordance with a potential of a control terminal. When a reference potential of the pixel fluctuates relatively to a reference potential of the readout circuit, a potential of the control terminal relative to a potential of a source of the load transistor is changed in a same phase with a fluctuation of the reference potential of the pixel.
