ISOCELL Bright HMX packs in 108 million pixels to capture and produce well-defined image with the fine details. With 108 million individual pixels in a large 1/1.33-inch size sensor making up a single image, a photo can stay sharp even when zoomed in or cropped. Smart-ISO technology that intelligently selects the native ISO optimizes dynamic range and reduces noise. To enhance low light photography, the ISOCELL Bright HMX transforms the 0.8um pixels into 1.6um pixels with Tetracell technology which merges neighboring four pixels to work as one.
