    摘要: A global shutter readout circuit includes a reset transistor coupled between a reset voltage and a bitline. A pixel enable transistor is coupled between the reset transistor and a source follower transistor. First and second terminals of the pixel enable transistor are coupled together in response to a pixel enable signal coupled to a third terminal of the pixel enable transistor. A first storage transistor coupled to the second terminal of the pixel enable transistor and the gate of the source follower transistor. A first storage capacitor is coupled to the first storage transistor. A second storage transistor coupled to the second terminal of the pixel enable transistor and the gate of the source follower transistor. A second storage capacitor is coupled to the second storage transistor. A row select transistor is coupled to the source follower transistor to generate an output signal from the global shutter readout circuit.

    摘要: Provided are a leakage light detection device, an imaging device, a leakage light detection method, and a non-transitory computer readable recording medium storing a leakage light detection program capable of improving quality of a captured image. A determination unit (11A) compares a pixel value (Gu3) of a pixel (G12) with a pixel value (Gb1) of a pixel (G14) and determines that the pixel (G12) has leakage light from a pixel (G11) in a case where the pixel value (Gu3) is larger than the pixel value (Gb1) by a threshold (TH) or more, and compares a pixel value (Gd3) of a pixel (G13) with the pixel value (Gb1) of the pixel (G14) and determines that the pixel (G13) has the leakage light from the pixel (G11) in a case where the pixel value (Gd3) is larger than the pixel value (Gb1) by the threshold (TH) or more.

    摘要: Imaging elements and imaging devices that reduce leakage of electric charges in a photoelectric conversion unit are disclosed. In one example, an imaging element includes photoelectric conversion units for generating an image signal corresponding to incident light. A charge retaining unit receives and retains sequentially transferred electric charges from the photoelectric conversion units. Charge transfer units are disposed for each of the photoelectric conversion units and transfer the electric charges to the charge retaining unit. Charge transfer signal lines are capacitively coupled to the charge retaining unit and are respectively connected to the charge transfer units to transmit a control signal. The charge transfer signal line connected to an earliest charge transfer unit that transfers the electric charges earliest in an image signal generation period is configured to have higher capacitance in the capacitive coupling than the other charge transfer signal lines.
