  • Patent number: 11822211
    Abstract: A focus adjustment device obtains a correction value for correcting a result of autofocus, from aberration information regarding at least one of an astigmatism, a chromatic aberration, and a spherical aberration of an imaging optical system, and focus detection information regarding the autofocus. The focus adjustment device then controls a position of a focusing lens that the imaging optical system has, based on a result of the autofocus corrected using the correction value. By correcting the result of the autofocus while considering at least a focus condition of a photographic image, a focus detection error caused by an aberration of the optical system can be accurately corrected.

  • Publication number: 20230209188
    Abstract: An image processing apparatus detects, from an image, a subject(s) of a first type and a subject(s) of a second type. The apparatus further detects a posture for each of the subject(s) of the first type. The apparatus then obtains, for each of the subject(s) of the first type, reliability that the subject is a main subject, based on the posture, and obtains a focus condition for each of the subject(s) of the first type and each of the subject(s) of the second type. The apparatus determines, based on the reliability and the focus condition, a main subject from the subject(s) of the first type and the subject(s) of the second type detected from the image.
