IMAGING DEVICE, CONTROL METHOD, AND PROGRAM - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240337826 titled 'IMAGING DEVICE, CONTROL METHOD, AND PROGRAM
Simplified Explanation: The imaging device described in the patent application includes an imaging element, a neutral density (nd) filter unit with multiple filter holders containing optical nd filters of varying transmittances, and a control unit that can adjust the transmittance by switching filters in and out of the optical path.
- The imaging device features a neutral density filter unit with multiple filter holders.
- Each filter holder contains optical nd filters with different transmittances.
- The control unit can adjust the transmittance by switching filters in and out of the optical path.
- When changing to a specific transmittance, the control unit simultaneously moves all filter holders in a coordinated manner.
Potential Applications: 1. Photography equipment for adjusting light exposure in different settings. 2. Cinematography tools for controlling light levels during filming. 3. Scientific imaging devices for precise light manipulation in experiments.
Problems Solved: 1. Inability to quickly adjust light exposure levels in imaging devices. 2. Limited control over light transmission in optical systems. 3. Difficulty in achieving consistent lighting conditions in various environments.

Original Abstract Submitted
an imaging device includes: an imaging element; a neutral density (nd) filter unit including a plurality of filter holders, each of the filter holders being mounted with a plurality of optical nd filters having different transmittances and being able to selectively insert the optical nd filters into an incident optical path for the imaging element; and a control unit. the control unit can variably set the transmittance of the nd filter unit by performing drive control of switching the optical nd filter to be inserted into the incident optical path for each of the plurality of filter holders, and in a case where driving of the plurality of filter bodies is required for switching to a target transmittance, performs control such that the plurality of filter holders to be driven is simultaneously displaced in a direction and a displacement amount equal to each other.
