摘要： A DSP calculates time integration of the light amount received by a CCD, using an input image. Determination is made regarding whether or not the light amount is equal to or smaller than a predetermined threshold. In a case that the light amount is equal to or smaller than the predetermined threshold, the DSP outputs a control signal to an AD converter for operation in the 8-bit mode. In a case that the light amount is greater than the threshold, the DSP outputs a control signal to the AD converter for operation in the 10-bit mode. The AD converter has a function of dynamic adjustment of conversion bits according to control from the DSP.

摘要： A multi-stage pipelined AD converter has n stages of conversion units, such as a first conversion unit, a second conversion unit, an (n−1)th conversion unit, and an nth conversion unit, which successively convert an analog signal into a digital signal each by several bits starting from the most significant bit. Each of the converted digital signals of several bits is combined in a digital output circuit. A first voltage source supplies a higher voltage than a second voltage source. The first voltage source supplies a high voltage to the first stage or the first conversion unit, while the second voltage source supplies a low voltage to the second and subsequent stages of the second conversion unit to the nth conversion unit which require a lower analog accuracy.

摘要： A first amplifier circuit samples and holds an input analog signal and outputs the same to a subtracting circuit. An AD converter circuit converts the input analog signal into a digital value so as to retrieve a predetermined number of bits. A DA converter circuit converts the digital value derived from conversion by the AD converter circuit into an analog value. A subtracter circuit subtracts an output analog signal from the DA converter circuit from the analog signal input via a first switch or the first amplifier circuit. A second amplifier circuit amplifies an output analog signal from the subtracter circuit by a gain of 2 and outputs the amplified signal. An input switching circuit controls the order of inputs, i.e. the input analog signal and a reference voltage, to voltage comparison elements constituting the Ad converter circuit.

摘要： A set of voltage output units outputs the light intensity detected by a photodetection device in the form of a voltage value. With the set of voltage output units, the capacitance of the cathode terminal of a photodiode PD provided within the pixel is charged or discharged using the photoelectric current. A current output unit outputs photoelectric current Iph flowing from the photodetection device. The current output unit includes a current output transistor provided between one terminal of the photodetection device and the data line. A pixel circuit effects control of the pixel so as to activate either the set of the voltage output units or the current output unit, thereby outputting either voltage value or photoelectric current to the data line connected to the pixel.
