Samsung hat seine Reihe an Isocell-Kamerasensoren um neue Modelle mit 0,7 μm Kantenlänge vorgestellt und will in erster Linie die Größe der Kameramodule damit schrumpfen können. Der bis dato 108 MP starke HM-Sensor bleibt in seiner maximalen Auflösung unverändert, aufgrund der reduzierten Kantenlänge konnte Samsung den neuen HM2-Sensor allerdings um 15 Prozent verkleinern und die Höhe um 10 Prozent. Neu ist außerdem die effektivere Lösung zur Phasendetektion beim Autofokus.
Samsung: Mehr Pixel auf weniger Fläche
Auch bei den weiteren neuen Sensoren hat Samsung die Größe verringern können, sodass der GW3 mit 64 MP jetzt so groß wie der 48 MP Sensor der vorherigen Generation ist. Weiterhin kann man viel darüber streiten, ob derartige Kamerasensoren für den Alltag eines Smartphone-Nutzers überhaupt sinnvoll sind, weil eine niedrigere Pixelgröße eigentlich gegen den üblichen Weg der Fotografie schwimmt.
Samsungs neue Kamerasensoren für Smartphones von 32 bis 108 MP:
- ISOCELL HM2 is Samsung’s third 108Mp image sensor following the HMX and HM1. The new 108Mp-sensor is around 15-percent smaller than the 0.8μm-based predecessors, and reduces the height of the camera module by 10 percent. The HM2 features Super PD, a faster and more effective phase detecting auto focus solution, and like the HM1, comes with a nine-pixel binning technology as well as 3x lossless zoom.
- ISOCELL GW3 is a 64Mp-image sensor optimized for mainstream devices. Thanks to the smaller pixel size, the GW3’s optical size is nearly identical to that of Samsung’s 0.8μm 48Mp image sensor. In addition to Tetracell and Smart-ISO technologies that help the sensor take bright images with high color fidelity, the GW3 is ideal for active lifestyles, featuring gyro-based electronic image stabilization (EIS) for sharper still photos and steadier videos. The image sensor supports video recording at up to 4K resolution at 60 frames-per-second (fps).
- ISOCELL GM5 is a versatile 48Mp-image sensor designed for use in telescoping or ultra-wide angle cameras. When used as a 5x optical telescoping sensor for folded-zoom, the GM5 takes full advantage of the compact 0.7μm pixel size that minimizes the camera bulge. For ultra-wide shots, the GM5 supports high-speed full-HD recording at 480fps. The sensor also offers a staggered-HDR feature, a faster and more power-efficient HDR technology that expedites image processing by sending a readout of long, medium, and short exposures of each row of pixels respectively to the mobile processor. As the readout is performed based on Tetracell’s 1.4μm two-by-two pixels, rather than at the individual 0.7μm-pixel level, staggered-HDR can provide brighter and clearer images with less noise.
- ISOCELL JD1 is the industry’s smallest 32Mp-image sensor at 1/3.14-inches, making it an ideal solution for smartphones with bezel-less displays that incorporate a hole-in-active-area or motorized pop-up mechanism for the front-facing camera. Even with 32-million pixels to capture a highly detailed selfie, the camera sits comfortably under the display as the height of the sensor’s camera module is comparable to those of 0.9μm 20Mp or 1.0μm 16Mp sensors. Like the GM5, the JD1 is also the one the first ISOCELL image sensors to offer staggered-HDR.
