Cameras in smartphones will get even better. Sony introduced 2×2 On-Chip Lens technology

According to rumors, such sensors will appear very soon.
Sony has introduced a new technology that will find application in image sensors for smartphones. If you believe the rumors, the upcoming Oppo Find X2, which will be released in the next quarter, will be one of the first to receive a camera with such a sensor. It is worth noting that the sensors themselves with the new technology, Sony has not yet represented.

Итак, технология называется 2×2 On-Chip Lens (OCL). Sony утверждает, что она повышает скорость фокусировки, обеспечивает высокое разрешение, высокую чувствительность и широкий динамический диапазон. Суть технологии достаточно проста и хорошо показана на изображении ниже.

In modern sensors, each pixel receives its own collective lens (lens-on-chip), and in the new technology, as you can see, four identical neighboring pixels receive a common lens. Apparently, the technology is designed for use only in Quad Bayer sensors.

In modern sensors, only certain selected pixels with no imaging functionality are used to determine the phase difference, and the number of such pixels is small. In the case of 2×2 On-Chip Lens (OCL) technology, all pixels can be used for these purposes, which increases the speed and accuracy of focusing, and also allows you to focus on small objects.

Sony itself does not say anything about the timing of the introduction of this technology in its image sensors.
