A system includes a storage device storing a set of instructions and at least one processor in communication with the storage device. When executing the instructions, the at least one processor is configured to cause the system to obtain a first operation mode of the optical filter and determine a brightness value of visible light of ambient light. The at least one processor may also cause the system to obtain a brightness threshold related to the first operation mode, compare the brightness value of the visible light of the ambient light with the brightness threshold, and determine whether a switching condition is satisfied based on the comparison result. Upon the determination that the switching condition is satisfied, the at least one processor may further cause the system to switch the first operation mode of the optical filter to a second operation mode.

Disclosed is a device for processing a camera image. The device for processing the camera image is configured to linearly control a noise removal intensity in accordance with a sensor gain amplification in an image obtained by an image capture device in a low luminance environment, and, when an object in the image is recognized, reduce the noise removal intensity in accordance with the speed of movement of the object, and thus, maintain a noise removal intensity having minimized motion blur.

To ensure high operability regarding a manipulation ring, without causing a decline in functionality.

An interlock member configured to be operated by rotational force of a rotationally-manipulated manipulation ring, and operate an optical element by transmitting the rotational force of the manipulation ring to the optical element is included, and a changeover mechanism configured to change over an operation direction of the optical element with respect to a rotation direction of the manipulation ring is provided at least on the interlock member. With this configuration, because an operation direction of the optical element with respect to a rotation direction of the manipulation ring is changed over by the changeover mechanism and the optical element is operated by the rotational force of the manipulation ring that is transmitted by the interlock member, the optical element is operated so as to follow a manipulation performed on the manipulation ring, an operation delay of the optical element rarely occurs, and high operability regarding the manipulation ring can be ensured without causing a decline in functionality.
