摘要： A solid-state image pickup device according to an embodiment is a solid-state image pickup device including a first pixel row, a second pixel row, and a third pixel row that are arranged in a horizontal direction. In the solid-state image pickup device, a first control pulse for transferring charges of first accumulation portions of the fourth and sixth CCD registers in a vertical direction perpendicular to the horizontal direction and a second control pulse for transferring charges of second accumulation portions of the fourth and sixth CCD registers in the horizontal direction are input to the fourth and sixth CCD registers such that an Hi period of the first control pulse and an Hi period of the second control pulse do not overlap each other in a timing period in which charges accumulated in the first, second, and third pixel rows are transferred.

摘要： The present disclosure relates to a solid-state imaging device and an electronic apparatus that can reduce the influence on an OPB pixel in a case where blooming has occurred in an aperture pixel. A solid-state imaging device that is one aspect of the present disclosure has a first photoelectric conversion portion, an upper electrode, and a lower electrode formed outside a substrate, the first photoelectric conversion portion performing photoelectric conversion in accordance with incident light, the upper electrode and the lower electrode being formed to sandwich the first photoelectric conversion portion. The solid-state imaging device includes: an aperture pixel that is disposed on a pixel array, and generates a normal pixel signal; an OPB pixel that is disposed at an end portion on the pixel array, and generates a pixel signal indicating a dark current component; and a charge releasing portion that is disposed between the aperture pixel and the OPB pixel, and releases electric charge flowing out from the aperture pixel. The present disclosure can be applied to back-illuminated vertical spectroscopic CMOS image sensors.

摘要： An image sensor pixel includes a photodiode disposed in a semiconductor material to generate image charge in response to light incident on a backside of the semiconductor material, and a pinning layer disposed in the semiconducting material and coupled to the photodiode. The pixel also includes a vertical overflow drain disposed in the semiconductor material and coupled to the pinning layer such that the pinning layer is disposed between the vertical overflow drain and the photodiode. A floating diffusion disposed in the semiconductor material proximate to the photodiode, and a vertical transfer transistor is disposed in part in the semiconductor material and coupled to the photodiode to transfer the image charge from the photodiode to the floating diffusion in response to a transfer signal applied to the gate terminal of the vertical transfer transistor.

摘要： The present disclosure relates to an imaging device, a driving method, and an electronic apparatus that can capture an image with a higher dynamic range. The imaging device includes a pixel region in which pixels are arranged, the pixels each including a photoelectric conversion unit that converts incident light into electric charges through electric conversion and stores the electric charges, and two or more charge storage units that store the electric charges transferred from the photoelectric conversion unit; and a drive unit that drives the pixels. The drive unit drives each pixel to cause the photoelectric conversion unit to repeatedly transfer electric charges with different exposure times to the two or more charge storage units during the light reception period of one frame. The present technology can be applied to an imaging device capable of capturing an HDR image, for example.
