Sony Corporation has recently announced a new IMX230 1/2.4″ 21-megapixel Exmor RS stacked camera sensor for smartphones. Recently, OmniVision had announced a similar camera sensor for high-end smartphones.
The new Sony IMX230 Exmor sensor has onboard image plane phase detection AF signal processing function. The new sensor promises best focus tracking of fast-moving subjects and the HDR function will enable you to capture both backgrounds and subjects clearly even in high-contrast scenes such as backlit locations.
Sony IMX230 camera sensor also supports 4K (4096 x 2160 pixels) Ultra HD videos and still images. The HDR (High Dynamic Range) imaging enables the camera to record still images and videos that reproduce details and rich gradations in the highlights and shadows of high-contrast scenes. The dedicated image plane phase detection AF pixels will be discretely incorporated into the screen of the image sensor, and the distance to the subject (range) and lens position for focusing will be calculated based on the information obtained from these dedicated pixels.
