Speaking of multimedia capture on mobile phones means referring to the multiplicity of sensors: more and more cameras, also more megapixels. This also means referring to two main manufacturers: Sony and Samsung, leading brands in the key component that allows photography and video capture. Although they are not the only ones that equip smartphones since Omnivision is a third widespread competitor. And it has weapons to deal with the big two, like its new OV48C sensor.

Omnivision Technology is a Taiwanese company based in the United States (California) that designs and manufactures electronic components for image capture and processing. Theirs are the sensors of many mobile phones, especially in the mid and low range (also in front or wide-angle cameras). And he has just developed a product that aspires to compete directly with the best of Sony and Samsung: the Omnivision OV48C. Said sensor has aptitudes, at least according to its technical sheet.
If we review the mobiles presented during 2019, there is a sensor that stands out above the rest, at least in terms of installation: the Sony IMX586. The Japanese manufacturer is number one in smartphones, followed by Samsung with its ISOCELL. Both companies display 48 MP sensors with 0.8 µm pixels that are grouped four by four using Pixel Binning to obtain the size of each pixel of 1.2 µm. Well, the Omnivision OV48C reserves that size for each pixel integrated into the sensor.
Large sensor size and 1.2 µm pixels
Having a large size for each pixel of the sensor predicts two consequences: the camera should obtain a higher level of detail and should be brighter. According to Omnivision, the OV48C meets both requirements: given the dimensions of each pixel, the mobiles that equip the sensor will obtain bright and detailed images without reducing the image size, directly by 48 MP. In addition, the Omnivision OV48C offers 12 MP Pixel Binning; resulting in a combined pixel size of 2.4 µm.The new Omnivision sensor has a size of 1.2 µm for each pixel; with 2.4 µm when processing by pixel combination
The final sensor size is one of the largest equipped in a smartphone: 1 / 1.3 “. In addition, the brand ensures that it is the first mobile sensor on the market that applies a dual conversion in the HDR to eliminate noise and artifacts. sensor promises to be a great ally of night mode, also of video capture in 4K and 8K. It can capture up to 15 images per second at maximum resolution (48 MP) and up to 60 fps at 12 MP and with Pixel Binning; with recording in slow motion at 1080p and 240 fps (or 720p and 360 fps).
The new sensor is already ready, but it is still far from that we can see it on smartphones: the brand has not yet anticipated the mobile futures that will equip it. On paper, it is a good alternative to the usual sensors of Sony and Samsung.
