A lens unit and a camera module in which the electrical wiring extending from the electrically functional component in the lens barrel can be guided to the image side without interfering with an assembly operation, without the need of ensuring a wiring space in the lens barrel, and without forming an elongated through hole in the lens barrel. The lens barrel includes: i) a first through hole extending in the longitudinal direction inside the side wall to guide the electric wiring from the component to the image side end of the flange; ii) a second through hole extending radially on the side wall so the first through hole can communicate with the outside of the barrel; iii) an accommodation groove on the outer peripheral surface of the side wall to communicate with the second through hole, in order to accommodate the wiring and guide the wiring to the image side.

The pixel region includes a first phase difference pixel group including a plurality of the phase difference pixels of which the first side of the photoelectric conversion element is blocked by the light blocking layer in a first side region of the first side, and a second phase difference pixel group including a plurality of the phase difference pixels of which the second side of the photoelectric conversion element is blocked by the light blocking layer. The first phase difference pixel group includes a first A pixel and a first B pixel in which a light blocking area of the photoelectric conversion element using the light blocking layer is smaller than that of the first A pixel. The controller performs addition readout processing in which at least one of a pixel signal of the first A pixel or a pixel signal of the first B pixel is weighted in accordance with optical characteristics of the imaging lens.

A method to perform a well maintenance operation is disclosed. The method includes obtaining, using a downhole camera, a downhole image comprising a pixel-based dimension of an object inside the wellbore, generating, using a laser distance pointer, a distance measurement of the object with respect to the downhole camera, determining, based on the distance measurement, a physical dimension of the object from the pixel-based dimension of the object, and performing the well maintenance operation based at least on the physical dimension of the object.

An auxiliary support and an external image capturing device. The auxiliary support includes a hooking member, a supporting member and a buffer member. The hooking member is configured to be hooked to a top of a first external structural member. One end of the supporting member is connected to the hooking member. The buffer member is connected to the end of the supporting member away from the hooking member and can deform plastically. The supporting member can be bent or curved such that the buffer member can abut against a second surface when the hooking member is hooked to the first external structural member. The buffer member can increase a supporting area, prevent the auxiliary support from shaking, reduce the pressure of the auxiliary support on the first external structural member, and prevent scratch or deformation of the first external structural member.
