FOCUS CONTROL APPARATUS, IMAGE PICKUP APPARATUS, AND FOCUS CONTROL METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18466329 titled 'FOCUS CONTROL APPARATUS, IMAGE PICKUP APPARATUS, AND FOCUS CONTROL METHOD

Simplified Explanation

The patent application describes an apparatus designed to perform focus tracking on an object within a detection area to detect a defocus amount within an imaging angle of view. The apparatus includes a memory storing instructions and a processor executing the instructions to determine whether focus tracking should be performed using information about the defocus amount and acquiring information about a shield against the object from image data generated by imaging. The processor then uses the acquired shield information in the focus tracking determination within the detection area.

  • Apparatus for focus tracking on an object within a detection area

Original Abstract Submitted

An apparatus configured to perform focus tracking on an object within a detection area to detect a defocus amount within an imaging angle of view includes a memory storing instructions, and a processor configured to execute the instructions to perform focus tracking determination to determine whether or not the focus tracking is to be performed using information about the defocus amount, and acquire information about a shield against the object from image data generated by imaging. The processor is configured to perform the focus tracking determination using information about the shield acquired in the detection area.
