Samsung Electro-Mechanics announced on the 1st that it has developed an optical 10x zoom folded camera module and is supplying it to global smartphone makers. It is the first in Korea to implement a folded-type optical 10x zoom in a smartphone camera.
Optical zoom is a function that pulls a distant subject closer and takes a picture without deteriorating the image quality. As the distance (focal length) between the image sensor and the lens increases, high magnification optical zoom is implemented.
Samsung Electro-Mechanics developed a dual folded camera module that doubled the focal length by refracting light twice and increased the camera module length by only 25%.
In addition, Samsung Electro-Mechanics applied its own lens cut off the top and bottom of the lens to reduce the height of the camera module. This lens is difficult to manufacture because it is difficult to adjust the flatness that affects the light transmittance.
In particular, the loss that may occur in the process of refraction of light is minimized with a low-loss surface coating technology. By applying a high-sensitivity sensor ball guide actuator, it is possible to obtain a clear picture with precise image stabilization even at a long lens working distance.
Ik-chan Shim, head of the module development team at Samsung Electro-Mechanics, said, “Recently, the camera module is used as a key differentiating point for smartphones, and the market demand for ultra-compact, high-magnification optical zoom is growing.” We are supplying differentiated products that customers want with our technology.”
Meanwhile, the camera module is used in various fields such as smartphones and automobiles. High-level technology such as high definition, compact size, slimming and low power consumption, and high rigidity is required.
