  • Publication number: 20240129630
    Abstract: An image-capturing system includes circuitry to receive multiple phase images for each of multiple phases. The multiple phase images include multiple first phase images captured under a first condition and one or more second phase images captured under a second condition different from the first condition, and the multiple first phase images are greater in number than the one or more second phase images. The circuitry calculates, for each of the multiple phases, a motion amount, at least, among the multiple first phase images of a same phase; performs correction on the multiple first phase images of the same phase based on the motion amount; and performs addition processing on the multiple first phase images of the same phase, so as to generate a summed phase image for each of the multiple phases.

  • Publication number: 20240123728
    Abstract: An image forming apparatus includes a head, a detector, and circuitry. The head forms an image on a recording medium. The detector detects a vertical movement of the recording medium and a distance to the recording medium in a vertical direction. The detector includes an optical sensor to project light to the recording medium and receive the light reflected from the recording medium. The circuitry sets a first area based on a result of detection performed by the detector. The first area is an area in which the recording medium and the head collide with each other. The circuitry retracts the head to prevent the recording medium and the head from colliding with each other, in a case where a position of the head is in the first area.
