摘要： An image sensor is provided including a pixel array, a correlated double sampling (CDS) unit, an analog-digital converting (ADC) unit, a control unit, and an overflow power voltage control unit. The pixel array includes at least one unit pixel that generates accumulated charges corresponding to incident light in a photoelectric conversion period and outputs an analog signal based on the accumulated charges in a readout period. The CDS unit generates an image signal by performing a CDS operation on the analog signal. An ADC unit converts the image signal into a digital signal. A control unit controls the pixel array, the CDS unit, and the ADC unit. An overflow power voltage control unit controls an overflow power voltage to have a low voltage level in the photoelectric conversion period and controls the overflow power voltage to have a high voltage level in the readout period.

摘要： To measure the distance to points on an object by radiating a periodic amplitude-modulated optical signal to the object and detecting the phase difference between the radiated optical signal and a reflected optical signal from the object, a first photo-detection control signal is generated to control the radiation of the optical signal. A mask signal is generated such that the mask signal is activated at least during a shuttering duration for resetting the voltage level at a sensing node (associated with an operation of a previous frame). A second photo-detection control signal is generated based on the first photo-detection signal and the mask signal such that the second photo-detection signal is deactivated or masked at least during the shuttering duration.

摘要： A linear-logarithmic image sensor includes a pixel array, a signal generation unit, and a control unit. The pixel array includes at least one unit pixel that generates a leakage signal corresponding to leakage photo-charges and that sequentially generates a first analog signal corresponding to a portion of accumulated photo-charges and a second analog signal corresponding to a whole of the accumulated photo-charges by resetting a floating diffusion node and transferring the accumulated photo-charges from a storage node to the floating diffusion node in response to first and second transfer control signals that are sequentially activated. The signal generation unit includes at least one signal generation block that generates a final analog signal based on the leakage signal, the first analog signal, and the second analog signal. The control unit controls the pixel array and the signal generation unit.
