An optical system includes, in order from an object side to an image side, a first unit and a second unit. The first unit includes a first substrate, and a first lens having a negative refractive power and disposed on the image side of the first substrate. The second unit includes a second substrate, and a second lens having a positive refractive power and disposed on the image side of the second substrate. An absolute value of the refractive power on an optical axis of the second lens is larger than that of the first lens. A surface on the image side of the first lens is an aspheric surface. In the aspheric surface of the first lens, a refractive power at an outermost peripheral portion of an effective area is smaller than a refractive power on the optical axis.

An aberration correction method and apparatus. The apparatus includes at least one processor, and an input/output unit configured to receive an captured image, wherein the processor is configured to initialize a first matrix or a second matrix by reducing a matrix of a point spread function (PSF) of a lens included in a capturing device used to capture the captured image, iteratively perform an aberration removal and a noise removal based on the captured image and the first matrix or the second matrix, and output a final original image as a result of the iteratively performing. Here, the first matrix is a matrix obtained by reducing the number of indices indicating light arrival points of the matrix of the PSF, and the second matrix is a matrix obtained by reducing the number of indices corresponding to light arrival points of a transposed matrix of the PSF.

A display device (e.g., in a contact lens) is mounted on the eye. The eye mounted display contains multiple sub-displays, each of which projects light to different retinal positions within a portion of the retina corresponding to the sub-display. Additionally, a “locally uniform resolution” mapping may be used to model the variable resolution of the eye. Accordingly, various aspects of the display device may be based on the locally uniform resolution mapping. For example, the light emitted from the sub-displays may be based on the locally uniform resolution mapping.

An example optical substrate, according to aspects of the present disclosure, includes a support structure, a plurality of lenses, and a plurality of flexures. Each flexure is engaged with the support structure and a respective lens for allowing independent lateral movements of the lenses during assembly of the optical substrate with another layer of an optical assembly. A first lateral movement provided by a first flexure of the plurality of flexures during the assembly is different from a second lateral movement provided by a second flexure of the plurality of flexures.

An image pickup apparatus includes an image pickup member and a laminated optical member that is fixed in frame-shaped fixed areas around respective optical path areas. The fixed areas include a first area and a second area. A width of the first area is greater than a width of the second area. In the laminated optical member, an optical surface central axis deviates from an optical axis toward the first area. In the image pickup member, an image pickup surface central axis that is a central axis of a first main surface deviates from the optical axis.

The present invention discloses a lens module and a system for producing an image. The lens module includes a print circuit board, a spacer, attached onto the print circuit board, and the spacer having a through hole; a lens assembly, supported by the spacer and covered the through hole; an image sensor, mounted on the print circuit board and electrically connected with the print circuit; the lens assembly is configured for capturing light reflected by an object and transmitting the light into the image sensor; the image sensor is configured for converting the light into raw image signals. The lens module may be a simple optics module and thinner than a related lens module.
