IMAGING APPARATUS AND CONTROL METHOD THEREOF - A simplified explanation of the abstract

This abstract first appeared for US patent application 18063183 titled 'IMAGING APPARATUS AND CONTROL METHOD THEREOF

Simplified Explanation

The patent application describes an imaging apparatus that includes an image sensor, acquiring unit, and at least one processor. The image sensor acquires paired signals from an imaging surface that captures an object image formed by an optical system. The acquiring unit determines defocus amounts from phase differences between the paired signals. The at least one processor functions as a detecting unit and a deciding unit. The detecting unit identifies an imaging object in an imaging frame, and the deciding unit determines the defocus amount to be used in focus control for the optical system based on the detected imaging object.

  • The imaging apparatus includes an image sensor, acquiring unit, and at least one processor.
  • The image sensor acquires paired signals from an imaging surface capturing an object image.
  • The paired signals are acquired by pupil division in different directions.
  • The acquiring unit determines defocus amounts from phase differences between the paired signals.
  • The at least one processor functions as a detecting unit and a deciding unit.
  • The detecting unit identifies an imaging object in an imaging frame.
  • The deciding unit determines the defocus amount for focus control based on the detected imaging object.

Original Abstract Submitted

An imaging apparatus includes an image sensor, an acquiring unit, and at least one processor. The image sensor is capable of acquiring, from an imaging surface that captures an object image formed by an optical system, first and second paired signals which are respectively acquired by pupil division in first and second directions different from each other. The acquiring unit acquires first and second defocus amounts from phase differences between the first paired signals and between the second paired signals, respectively. The at least one processor functions as a detecting unit and a deciding unit. The detecting unit detects an imaging object in an imaging frame. The deciding unit decides, based on the detected imaging object, at least one defocus amount to be used in focus control for the optical system from the first and second defocus amounts.
