IMAGE CAPTURING APPARATUS, ASSISTING METHOD FOR FOCUS CONTROL, AND STORAGE MEDIUM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18358138 titled 'IMAGE CAPTURING APPARATUS, ASSISTING METHOD FOR FOCUS CONTROL, AND STORAGE MEDIUM

Simplified Explanation

The abstract describes an image capturing apparatus that includes an operation member to move the focus lens in an attached optical system. The apparatus also has a recording unit that records the position of the focus lens as an index value in a memory, along with information about the attached optical system. An acquisition unit is used to acquire information for identifying the attached optical system, and a readout unit reads out the index value from the memory if there is a recorded index value associated with the acquired information. A control unit then controls a display device to show the read index value and the current position of the focus lens.

  • The apparatus includes an operation member to move the focus lens in the attached optical system.
  • A recording unit records the position of the focus lens as an index value in a memory.
  • The index value is associated with information about the attached optical system.
  • An acquisition unit is used to acquire information for identifying the attached optical system.
  • A readout unit reads out the index value from the memory if there is a recorded index value associated with the acquired information.
  • A control unit controls a display device to show the read index value and the current position of the focus lens.

Potential applications of this technology:

  • Photography: The image capturing apparatus can be used in cameras to accurately record and display the position of the focus lens, allowing photographers to easily adjust and track the focus.
  • Videography: The apparatus can also be used in video cameras to ensure precise focus during video recording.
  • Microscopy: The technology can be applied in microscopy systems to track and display the position of the focus lens, aiding in precise sample imaging.

Problems solved by this technology:

  • Accurate focus adjustment: The apparatus allows for precise control and tracking of the focus lens position, ensuring accurate focus in image capturing.
  • Indexing of focus lens position: The recording and readout of the index value allows for easy reference and retrieval of the focus lens position information.
  • Identification of attached optical system: The acquisition unit helps identify the specific optical system attached to the apparatus, allowing for customized control and display.

Benefits of this technology:

  • Improved image quality: Accurate focus adjustment ensures sharper and clearer images.
  • Ease of use: The display of the focus lens position and index value provides a user-friendly interface for adjusting and tracking focus.
  • Customization: The identification of the attached optical system allows for tailored control and display, optimizing the user experience.


Original Abstract Submitted

An image capturing apparatus comprises: an operation member used to move a position of focus lens included in an attached optical system; a recording unit that records the position of the focus lens as an index value in a memory in association with information of the attached optical system including the focus lens in response to a registration instruction; an acquisition unit that acquires information for identifying the attached optical system; a readout unit that, if there is an index value recorded in association with the information of the attached optical system corresponding to the information acquired by the acquisition unit, reads out the index value from the memory; and a control unit that controls a display device to display the read index value and a current position of the focus lens.
