Samsung Expands Advanced 0.7μm-Pixel ISOCELL Image Sensor

The new Samsung image sensors are aiming to reduce physical space occupied by camera sensors and also offer high resolutions.

Following the launch of the 50MP ISOCELL GN1 image sensor earlier this year in May, Samsung has now announced a new lineup of ISOCELL image sensors for its 0.7μm pixel product lineup.

Other than shrinking the sensors, the light reception on them is also improved by the ISOCELL 2.0 which enhances the wall structure between cells. The new sensor is 15 percent smaller than the 0.8μm-based predecessors and reduces the height of the camera module by 10 percent.

The latest 0.7-micrometer pixel-based image sensors are up to 15 percent smaller than the products with 0.8-micrometer pixels of the same resolution and can reduce the height of the camera module by up to 10 percent, allowing smartphone manufacturers to develop handsets with sleeker designs, Samsung said. Alongside the size, the new lineup includes Samsung's latest image sensing technologies created to collect the maximum amount of light for better image quality.

Leading the charge is the Samsung Isocell HM2, which is Samsung's third 108MP sensor.

The new sensor of 108 MP is the successor of the models HMX and HM1, being slightly smaller than these components and allowing a better detection of the autofocus. Samsung is the world's second largest supplier of mobile image sensors after Sony. To retain the same bright photos, Samsung has incorporated advanced ISOCELL Plus and Smart-ISO technologies. It can double up as a telephoto (up to 5x optical zoom) and an ultra-wide-angle lens, depending on the use case.

Finally, the JD1 is indicated for front-facing pop-up cameras or with holes in the screen, as it is economical in space and still maintains high resolution. It is a 1/2.55-inch sensor with 48MP resolution, 2×2 pixel binning, and staggered HDR. 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.

Samsung, the world's leading memory chip and smartphone maker, said ISOCELL HM2, GW3 and JD 1 products are now in mass production, while sampling GM5. 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. In bright light, the sensor receives an image close to the declared resolution, and in case of a lack of light, adjacent pixels are combined into a 2 × 2 array, and diodes of 1.4 μm are obtained with a resulting resolution four times lower, but with increased sensitivity.

In June 2018, Samsung introduced an upgraded pixel isolation technology, the ISOCELL Plus.
