OmniVision has introduced a 64-megapixel mobile image sensor with large 1-micron pixels

This year, OmniVision has already released two 64-megapixel sensors for smartphones – OV64B (with a pixel size of 0.7 μm) and OV64C (with a pixel size of 0.8 μm). But miniaturization means reducing the light falling on the matrix, so now there is a sensor OV64A with larger pixels of 1 μm.

As it is accepted today, the Quad Bayer structure (a method of placing Bayer light filters to cover not individual pixels, but cells of four light-sensitive elements) with a hardware demosaic algorithm to increase energy efficiency is used. Like other similar matrices, the novelty can display a picture in 64 MP (9248 × 6944 pixels) and in 16-MP mode with improved light sensitivity and dynamic range (in the latter case, the size of quadropixels is 2 microns).

The physical size of 64-MP OV64A is 1 / 1.34 “- about the same as modern 108-MP matrices with 0.8-μm pixels. The sensor uses PureCel Plus-S technology – the equivalent of Samsung ISOCELL Plus. In other words, special partitions between pixels are used, which allow to capture photons more efficiently and accurately, increasing the light sensitivity and color rendering compared to conventional BSI sensors.

As for video, the OV64A sensor is capable of recording 8K at up to 30 fps, 4K at up to 120 fps and even writing 64-megapixel video (conventionally 10K) at 15 fps (if anyone needs it).

The new sensor is designed to expand OmniVision’s share of the smartphone market, which is currently 9%. It is possible that the company will be able to take second place after Sony and bypass Samsung. The OV64A sensor will be available to smartphone manufacturers by the end of this year, and will appear in ready-made devices in early 2021.
