    摘要： An overlight amount detection circuit (1) according to the present disclosure includes a MOS transistor and a high-impedance element (Ca). A source of the MOS transistor (Mn1) is connected to a vertical signal line (VSL) of an image sensor. The high-impedance element (Ca) is connected to a drain of the MOS transistor (Mn1). The overlight amount detection circuit (1) detects a potential fluctuation of the vertical signal line (VSL) based on a potential defined by a gate potential of the MOS transistor (Mn1), and outputs a potential of a contact point between the drain of the MOS transistor (Mn1) and the high-impedance element (Ca) as a signal indicating an overlight amount detection result.

    摘要： To prevent leakage of incident light to a charge holding unit of an imaging element. The pixel includes a photoelectric conversion unit disposed on a side of the light receiving face of the semiconductor substrate, a charge holding unit disposed on a side different from the light receiving face of the semiconductor substrate, and a charge transfer unit that transfers a charge to the charge holding unit, and is configured to have a rectangular shape in a light receiving face view. The charge holding unit light shielding film is configured to have a band shape adjacent to three sides including a first side that is one of the sides of the rectangle and parallel to the first side in a light receiving face view, is adjacent to a semiconductor region including the charge transfer unit in a light receiving face view, and is disposed in the pixel between the photoelectric conversion unit and the charge holding unit to shield incident light. The charge transfer unit light shielding film is configured to have a band shape adjacent to three sides including a second side that is a side facing the first side in a light receiving face view and parallel to the second side, and is configured to be disposed in the pixel between the photoelectric conversion unit and the charge transfer unit to shield incident light and have a shape which has an end portion overlapping an end portion of the charge holding unit light shielding film in a light receiving face view.

    摘要： An image processing device includes a memory for storing reference color ratios and crosstalk values of each of light source images acquired by sensing light sources having different wavelengths. The image processing device also includes a processor for receiving an image including a plurality of regions each including outer pixel values and inner pixel values of the same color, and correcting the outer pixel values or the inner pixel values by using difference values between the respective reference color ratios and a color ratio of the image as weights of the crosstalk values.

    摘要： An examination apparatus detecting first reflected light from a first eye of a subject and second reflected light from a second eye of the subject includes an imaging device, and a processing unit. The imaging device includes pixels each including a first photoelectric conversion unit and a second photoelectric conversion unit. The processing unit includes a unit configured to acquire a first signal based on the first reflected light entering the first photoelectric conversion units and a second signal based on the second reflected light entering the second photoelectric conversion units, a unit configured to acquire crosstalk amounts of the first and second signals based on information about positions of the first and second eyes, and a unit configured to generate correction signals based on the first and second signals and amounts of the crosstalk.
