Abstract
An imaging device includes an imaging unit configured to generate a moving-image signal by capturing an image of a subject formed by an imaging optical system, a focus adjustment information acquisition unit configured to acquire focus adjustment information related to human subjective focus adjustment, and a focus adjustment determination unit configured to determine behavior of the focus adjustment of the imaging unit using the focus adjustment information obtained by the focus adjustment information acquisition unit.
Claims18
An imaging device comprising:
- an imaging sensor configured to capture an image of a subject formed by an imaging optical system and to generate a moving-image signal based on the captured image;
- and
- a processor comprising hardware, wherein the processor is configured to implement:
- a focus adjustment information acquisition unit configured to acquire focus adjustment information related to human subjective focus adjustment;
- and
- a focus adjustment determination unit configured to determine behavior of a focus adjustment of the imaging optical system based on the focus adjustment information obtained by the focus adjustment information acquisition unit,
- wherein the focus adjustment information is information based on a physical focus adjustment characteristic of a human eyeball, or information obtained by approximating the physical focus adjustment characteristic of the human eyeball, and
- wherein the physical focus adjustment characteristic of the human eyeball is a temporal characteristic from a focus adjustment start to a focused state.
A non-transitory computer-readable storage medium storing a program for causing an imaging device having an imaging sensor configured to capture images of a subject formed by an imaging optical system and to generate a moving-image signal based on the captured images, to execute:
- a focus adjustment information acquisition step of acquiring focus adjustment information related to human subjective focus adjustment;
- and
- a focus adjustment determination step of determining behavior of a focus adjustment of the imaging optical system based on the focus adjustment information acquired in the focus adjustment information acquisition step,
- wherein the focus adjustment information is information on a physical focus adjustment characteristic of a human eyeball or information obtained by approximating the physical focus adjustment characteristic of the human eyeball, and
- wherein the physical focus adjustment characteristic of the human eyeball is a temporal characteristic from a focus adjustment start to a focused state.
