An optical apparatus evaluating method includes the steps of acquiring first data on a performance of an optical apparatus, which changes along with use of the optical apparatus, acquiring second data on a reference performance of the optical apparatus, and evaluating the performance of the optical apparatus using the first data and the second data.

A wearable device includes: a body, a driving assembly, and a camera assembly. The body includes a working surface and a side wall connected to an edge of the working surface. The driving assembly is connected to the body and includes an adjusting component and a supporting component that protrude from the side wall. The adjusting component and the supporting component are rotatable relative to each other in a plane perpendicular to the working surface. The camera assembly includes a lens connected to the adjusting component and an image sensor connected to the supporting component. The relative rotation of the adjusting component and the supporting component drives the lens to move linearly in a direction perpendicular to a photosensitive surface of the image sensor.

[Object] To provide a vehicle-mounted camera that is capable of capturing a high-quality image. [Solving Means] A vehicle-mounted camera includes an imaging device, a housing, and an optical system. The housing includes an accommodation portion that accommodates the imaging device, an outer face that is exposed to an outer space, an opening that causes the accommodation portion and the outer space to communicate with each other, and a functional portion that forms at least a portion of the outer face, the functional portion being a functional portion that absorbs visible light from among light entering from the outer space and off which infrared light from among the light entering from the outer space is reflected. The optical system causes light entering the opening from the outer space to be imaged onto the imaging device.

An instrument manipulator and a robotic surgical system including an instrument manipulator are provided. In one embodiment, an instrument manipulator includes a plurality of independent actuator drive modules, each of the plurality of actuator drive modules including an actuator output, wherein each of the actuator outputs are configured to independently actuate a corresponding actuator input of a surgical instrument without force input from another actuator output. The instrument manipulator further includes a frame housing the plurality of independent actuator drive modules, the frame including a distal end from which each of the actuator outputs distally protrude for engaging the corresponding actuator inputs of the surgical instrument.

Systems and methods for macro stereo time-lapse photography, producing a stereographic time-lapse digital video, and macro stereographic time-lapse digital videos. A method of producing a sequence of time-lapse stereographic images of a subject, by positioning a camera with a macro lens at a first position relative to the subject; using the camera to obtain a first stack of images of the subject from the first position; positioning the camera at a second position relative to the subject; using the camera to obtain a second stack of images of the subject from the second position; and storing the first stack of images and the second stack of images as a stack pair; and then selectively repeating.

A liquid lens module includes a first plate comprising a cavity accommodating a conductive liquid and a non-conductive liquid; second and third plates disposed above and below the first plate, respectively; and first and second electrodes disposed on one side and another side of the first plate, respectively, wherein a ratio of a thickness of the first plate to a width of an incidence opening formed below the second plate in the cavity is greater than 0.3.

A projection lens, which is a projection lens to be attached to a projection apparatus body having an electro-optical device, includes: a first focus optical system; a first holding portion that has an attachment portion and on which light along a first optical axis extending in first directions is incident; and an adjustment frame that holds the first focus optical system. When one of the first directions is defined as a first A direction and the other of the first directions is defined as a first B direction, the first focus optical system is positioned further in the first A direction than the attachment portion, and light along the first optical axis travels in the first B direction. The adjustment frame is movable in the first directions relative to the first holding portion.

A photographing device includes a body, an optical assembly mounted at the body, a display assembly, a focus adjustment assembly, and a control apparatus including a memory storing program codes and a processor. The processor is configured to execute the program codes to, obtain a current adjustment position of the focus adjustment assembly, calculate a current focus value corresponding to the current adjustment position of the focus adjustment assembly according to the current adjustment position of the focus adjustment assembly, and, in response to the current focus value being equal to a focus parameter peak value and the adjustment position of the focus adjustment assembly continuing to change, control the focus adjustment assembly to stop focusing within a preset time period starting from a time at which the current focus value is equal to the focus parameter peak value.
