    Abstract: The present invention provides a solid-state imaging apparatus that can significantly reduce kTC noise by using a negative feedback amplifying circuit. A solid-state imaging apparatus includes a pixel unit including a plurality of pixels arranged on a semiconductor substrate in a matrix, the pixel unit including, for each column, a source line and a column signal line, each of the plurality of pixels including: a photoelectric conversion unit that generates a signal charge corresponding to incident light; a storage unit storing the signal charge; a reset transistor; an amplifying transistor; and a cutoff transistor, wherein the amplifying transistor and the cutoff transistor form a negative feedback amplifying circuit. With this configuration, kTC noise can significantly be reduced.

    Abstract: A solid-state imaging device includes a substrate of P type and a wiring layer. The substrate includes: a first semiconductor region disposed on a first principle surface and extending in a direction from the first principal surface toward the second principal surface; a second semiconductor region disposed between the second principal surface and the first semiconductor region and connected to the first semiconductor region; a P type semiconductor region disposed between the second principal surface and the second semiconductor regions of two pixels; and a pixel isolation region disposed inside the substrate, between the first semiconductor regions of the two pixels. The second semiconductor region and the P type semiconductor region form an avalanche multiplication region.

    Abstract: An image forming apparatus includes an imager that is electrically connected to an image sensor disposed at a position where light that has passed through a sample slice is incident on the image sensor, and an illumination system that emits illumination light successively in different illumination directions relative to a sample slice to illuminate the sample slice with the illumination light and that emits a first light having a peak in a first wavelength range and a second light having a peak in a second wavelength range. The image forming apparatus obtains a plurality of first-color images with the image sensor while the sample slice is being illuminated with the first light serving as the illumination light successively in the different illumination directions. The image forming apparatus obtains at least one second-color image with the image sensor while the sample slice is being illuminated with the second light in at least one of the different illumination directions. The image forming apparatus generates a high-resolution image on the basis of the plurality of first-color images and the at least one second-color image.

    Abstract: A solid-state imaging device includes a detector, a count value storage, and a reader. The detector includes an avalanche amplification type light receiving element that detects a photon, and a resetter that resets an output potential of the light receiving element, and outputs a digital signal that indicates the presence or absence of incidence of a photon on the light receiving element. The count value storage performs counting by converting the digital signal output from the detector to an analog voltage, and stores the result of counting as a count value. The reader outputs an analog signal indicating the count value.
