Following the introduction of the 50MP ISOCELL GN1 image sensor at the beginning of May this year, Samsung has now announced a new range of ISOCELL image sensors for its 0.7 μm pixel product line. The new range includes four sensors – 108 MP ISOCELL HM2, 64 MP ISOCELL GW3, 48 MP ISOCELL GM5 and 32 MP ISOCELL JD1 – that are 15 percent smaller than the 0.8 μm sensors with the same resolution and height of the camera module by up to 10 percent. Thanks to the smaller form factor, the new ISOCELL sensors could help OEMs reduce the size of the camera bump in future smartphones.
Yongin Park, Executive Vice President of the Sensor Business at Samsung Electronics, said of the new ISOCELL sensor range: “Samsung continues to lead innovations like ISOCELL Plus and Smart ISO to provide more pixels in a smaller package. Last year, Samsung introduced the industry’s first 0.7 μm pixel image sensor and the first 108 megapixel sensors. Now we’re bringing more advanced pixel technologies to mobile cameras in a variety of options, enabling high definition images and sleeker designs in a wider range of tomorrow’s mobile devices. “
In order to ensure that the new 0.7 μm ISOCELL sensors can collect enough light despite the smaller pixel size, Samsung has integrated the ISOCELL Plus and Smart ISO technologies into the sensors. In addition, Samsung has announced that it will introduce an improved pixel technology called ISOCELL 2.0 for upcoming 0.7 μm products later this year. It is expected that the new technology will further improve the wall structure between the cells, resulting in an additional light sensitivity of up to 12 percent compared to the current ISOCELL Plus technology.
Below is more information about the technologies used in Samsung’s latest line of ISOCELL image sensors:
- ISOCELL HM2 is Samsung’s third 108MP image sensor, following the HMX and HM1. The new sensor is 15 percent smaller than its predecessor based on 0.8 μm and reduces the height of the camera module by 10 percent. The HM2 has Super PD, a faster and more effective phase detection autofocus solution, and is similar to the HM1 with nine-pixel binning technology and loss-free 3x zoom.
- ISOCELL GW3 is a 64MP sensor that is optimized for mainstream devices. Due to its smaller pixel size, the optical size of the GW3 is almost identical to that of the Samsung 0.8 μm 48MP sensor. The sensor features technologies such as Tetracell and Smart ISO, which allow users to capture bright images with high color fidelity, as well as gyro-based electronic image stabilization (EIS) for sharper still images and more stable videos. The sensor supports video recordings with a resolution of up to 4K at 60 frames per second.
- ISOCELL GM5 is a 48MP sensor for use in telescope or ultra-wide angle cameras. When used as an optical 5x zoom sensor, the GM5 can take full advantage of its compact pixel size of 0.7 μm in order to minimize the bulging of the camera. For wide-angle shots, the sensor supports high-speed FHD shots at 480 frames per second. In addition, the sensor offers staggered HDR, a faster and more energy efficient HDR technology that improves image processing time by sending an indication of long, medium and short exposures of each row of pixels to the processor. Since the readout is based on Tetracells 1.4 μm two-by-two pixels, staggered HDR can deliver brighter and clearer images with less noise.
- ISOCELL JD1 is the smallest 32-megapixel sensor in the industry, measuring just 1 / 3.14 inch. This makes it an ideal selfie camera for smartphones with a punch cutout or a motorized opening mechanism. The height of the sensor is comparable to that of the 0.9 μm 20MP or 1.0 μm 16MP sensors, which makes it a great fit on the front of a device. Similar to the GM5, the JD1 also supports staggered HDR technology.
Of the four new sensors, ISOCELL HM2, GW3 and JD1 are already in mass production and we expect these new sensors to be seen in upcoming smartphones sometime later this year or early next year. Samsung is currently testing the ISOCELL GM5 and devices with this 48MP sensor may be released at a later date.
