Samsung Electro-Mechanics (009150)Developed an optical 10x zoom folded camera module and started supplying it to global smartphone makers. It is the first in Korea to implement a folded-type optical 10x zoom in a smartphone camera.
According to Samsung Electro-Mechanics on the 1st, the product developed this time refracts light twice to double the focal length while increasing the camera module length by only 25%. Optical zoom is a function to take a picture by pulling a distant subject closer without deterioration in image quality. As the distance between the image sensor and the lens, that is, the focal length increases, a high magnification optical zoom is realized.
Previously, in 2019, Samsung Electro-Mechanics developed a folded camera module that secured a focal length by refracting light in the form of a periscope, and succeeded in implementing a 5x optical zoom without a’katuktu’. However, even if the folded method is applied, if the optical zoom magnification is enlarged, the length of the camera module increases and the space efficiency in the smartphone decreases. To solve this problem, Samsung Electro-Mechanics introduced a new product by applying a dual folded camera module in a way that refracts light twice. When implementing the optical 10x zoom in a general way, the thickness of the smartphone is at least 3 times thicker than the current product, but it is a camera module that solves this.

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, this new product minimizes the loss that may occur in the process of refraction of light with a low-loss surface coating technology, and 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 operating distance. Ik-chan Shim, executive director of the module development team at Samsung Electro-Mechanics, said, “Recently, camera modules are used as a major differentiating point for smartphones, and the market demand for ultra-small and high-magnification optical zoom is growing.” , We are supplying differentiated products that customers want with our own technology to manufacture.”
Meanwhile, the camera module is used in various fields such as smartphones and automobiles. Camera module production requires high-level technology that can meet high-definition, miniaturization, slimming, and low power consumption. Samsung Electro-Mechanics supplies camera modules to major smartphone makers based on core technologies required for camera modules, such as lens design, mold technology, and internalization of high-performance actuator manufacturing, and expands transactions with global automobile companies based on the technologies accumulated in mobile.
