Abstract: Methods, systems, and apparatus for image processing are provided. In one aspect, a method includes: acquiring an image to be processed that involves a target object, extracting image noise information and contour information of the target object from the image to be processed, generating a noise distribution image based on the image noise information and the contour information of the target object, and obtaining a target image by performing noise reduction on the image to be processed with the noise distribution image.

Abstract: An assembling method of a coil and an elastic plate of a voice coil motor assembly includes step 1: winding a coil around a support body of a coil support of a sleeve having an upper flange and a lower flange, and the support body disposed between the upper flange and the lower flange, an outer edge of the upper flange having at least two opposing protrusions; step 2: installing two opposing lower elastic plates on an upper surface of the support through an automation apparatus, two opposing lower elastic plates being respectively stacked above the two opposing protrusions; step 3: placing the support stacked with the lower elastic plates in a welding apparatus, contact positions of the two lower elastic plates and the two protrusions being an area of contact positions of the lower elastic plates; and step 4: soldering tin on the solder paste or fixing by laser welding.

Abstract: A voice coil motor includes a coil support, a coil wound on the coil support, and two opposing lower elastic plates disposed on an upper part of the coil support. The outer edge of an upper flange of the coil support has at least two opposing protrusions which are arranged radially. The coil has a head end and a tail end which are respectively wound on the two protrusions. The two lower elastic plates are respectively connected with the coil wound on the two protrusions by welding. To prevent the head end from slanting, the lower elastic plates are mounted on the coil support through the operation of an automation apparatus to be soldered with the coil wound on the protrusions. The connection of the coil and the lower elastic plates is thus firm.
