  • Publication number: 20240276119
    Abstract: An image capturing apparatus comprise a plurality of pixels and a correction unit. Each pixel includes: a photoelectric converter that photoelectrically converts incident light into charge; first and second charge holding sections that hold charge obtained by the photoelectric converter with first and second charge accumulation periods, respectively, and first and second floating diffusion portions that read out first and second signals corresponding to the charges held in the first and second charge holding sections. The correction unit corrects signal levels of the first signal and the second signal based on a difference in capacitance between the first and second floating diffusion portions.

  • Patent number: 11525665
    Abstract: To optimize an imaging range in a depth direction in terms of a relationship with a resolution, an OCT apparatus includes a signal processor that determines a reflected light intensity distribution of an imaging object on the basis of a spectrum of a detected interference light. The signal processor performs spectrum conversion, having a conversion characteristic with which a light source spectrum is converted to a Gaussian distribution curve, on the spectrum of the interference light, and determines the reflected light intensity distribution by Fourier-transforming a spectrum resulting from the spectrum conversion. In the conversion characteristic, the light source spectrum and the Gaussian distribution curve have center wavelengths differing from each other.

  • Patent number: 11467526
    Abstract: When a sheet jam is detected, a processor may perform the following process. In a case where a sheet is spanning a first conveyance path and a drawer unit, the processor maintains a lock unit in a locked state by supplying power to the lock unit via the drawer unit from a power supply without depending on whether a door is in an open state or a closed state. In a case where a sheet is not spanning the first conveyance path and the drawer unit, the processor controls supplying and disconnecting of power to the drawer unit from the power supply in accordance with whether the door is in a closed state or an open state.

  • Patent number: 11187519
    Abstract: In an OCT imaging, a focus position in a tomographic image is determined by a first distance, a second adjustment amount, a third adjustment amount and a refractive index of a medium. The first distance is a distance between a first surface and a second surface of a wall part of a container. The second adjustment amount is a focus position adjustment amount of an objective optical system at which an intensity of reflected light from the second surface is maximized when a reference mirror is positioned at a position where an object optical path length to the first surface and a reference optical path length are equal in a condition that the objective optical system is focused on the first surface. The third adjustment amount is a focus position adjustment amount in the imaging.
