[b]SONY Starvis 2 sensor generation with ClearHDR feature[/b]=p-technology-detail-full__function-top__text u-SST-Light p-w55-text__mbImage sensors can adjust the length of time to take in light (exposure time) to output images, optimized according to the brightness of the scene. A short exposure time in a bright environment avoids oversaturation of the photodiode and a long exposure time in a dark environment ensures the collection of a sufficient amount of light.=p-technology-detail-full__function-top__text u-SST-LightIn contexts where both extremely bright and dark areas are in view, such as a strong light source next to a tunnel exit, these areas of the image may be over- or under-exposed and details could be lost. When we can see details in both bright and dark areas of an image, it is said to have a high dynamic range, and the attribute for realizing this is called a high dynamic range (HDR) feature.[b]Clear HDR[/b]=p-technology-detail-full__function-top__text u-SST-Light p-w55-text__mbWhen the Clear HDR feature is on, the image sensor captures two images simultaneously, one with a low gain level set to the bright region and the other with a high gain level adjusted to the dark region. The images are then synthesized.
