Mobile phone image sensor hits 108Mpixels
The HM3 is in a 1-inch by 1.33-inch format with 0.8-micron pixels.
For faster auto-focus, the HM3 integrates an improved Super PD Plus feature. Super PD Plus adds autofocus-optimized micro-lenses over the phase detection focusing agents, increasing measurement accuracy of the agents by 50-percent. The enhanced phase detection auto-focusing (PDAF) solution helps to keep moving subjects in sharp focus and delivers optimum results in dark environments.
In mixed light environments, such as at the end of a tunnel, the HM3 adopts Smart ISO Pro, a high-dynamic-range (HDR) imaging technology which uses an intra-scene dual conversion gain (iDCG) solution. Smart ISO Pro simultaneously captures a frame in both high and low ISO, then merges them into a single image in 12-bit color depth and with reduced noise. As Smart ISO Pro does not require multiple exposure shots to create a standard HDR image, it can significantly reduce motion-artifacts. In addition, with a low-noise mode, it improves the light sensitivity by 50-percent to capture brighter and clearer results in low-light environments than its predecessor.
The HM3’s pixel layout is especially arranged in three-by-three single color structures suitable for nine-pixel binning. By merging nine neighboring pixels, the 108Mp HM3 mimics a 12Mp image sensor with large 2.4μm-pixels, heightening light sensitivity when taking photographs in low-light environments. With an improved binning hardware IP, the HM3 supports seamless transitions between 108Mpixel and 12Mpixel resolutions.
Designs of the new sensor has also been optimized to reduce energy usage under preview mode by 6.5-percent, offering added power efficiency to the overall mobile device.
The HM3 is currently in mass production.
