Sony recently introduced the IMX586, the company's latest image sensor offering for smartphones. The Japanese technology company claims that their latest product is the first sensor to feature an ultra-compact 0.8 micron pixel size. In addition, this product with a resolution of 48 megapixels offers the highest number of pixels among image sensors, which are aimed at mobile phones. The increased resolution of the IMX586 sensor should enable smartphones to capture high-resolution images even when using digital zoom, and the compact size of the 8.0-millimeter product enables tech companies to incorporate the sensor into many smartphones.
While the pixel size is small If the sensor allows for higher resolution, this will negatively affect the quality of the images taken by the camera, especially in low light conditions. Therefore, Sony has integrated technologies that are designed to improve the product's ability to collect light. For example, the sensor uses a Quad Bayer color filter array that places the pixels in squares that each contain four pixels of the same color in low light conditions. While this setup reduces the effective resolution of the sensor to 1
Apart from Sony Tech companies are also developing sensors with smaller pixel sizes and increased resolution. For example, South Korean tech giants Samsung recently introduced a new imaging technology called ISOCELL Plus, which improves the photosensitivity and color fidelity of sensors by replacing the metal grid that separates the pixels with a new material that reflects less incident light. Samsung noted that this technology allows the development of sensors with pixel sizes of 0.8 microns and resolutions of 20 megapixels or even higher. Samples of Sony's IMX586 modules will ship to device manufacturers in September 2018. The price is JPY3,000, which equates to US $ 27 at the current exchange rate.
