  • Patent number: 11854239
    Abstract: An imaging device acquires an input image using a lens unit and an imaging element and detects a subject. The imaging device calculates a reliability of detection of a subject and compares the reliability with a threshold value. When the reliability of detection of a subject is less than the threshold value, the imaging device performs a defocus calculating process and a background area determining process. The imaging device performs a low-pass filtering process on the determined background area, decreases a high-frequency component in the background area, and then detects a subject again.

  • Publication number: 20230276117
    Abstract: A main object determination apparatus includes an image acquisition unit configured to acquire images captured at different timings, a selection unit configured to select main object candidate(s) from objects in the images, a determination unit configured to determine whether the main object candidate(s) each selected at the respective different timings are the same, and an input unit configured to receive an operation. In a case where the determination unit determines that the main object candidate(s) selected by the selection unit in an image of interest and one or more images captured within a predetermined time before the image of interest is captured are the same, the determination unit determines the main object candidate(s) to be a main object. In a case where the input unit receives an instruction to specify a new main object, the determination unit switches the main object according to the instruction.
