The Japanese company Hitachi is not particularly well-known in the world for its achievements in the field of photo and video equipment; nevertheless, this area is very interesting for the manufacturer, and its specialists are constantly doing some research in this direction. In one of the latest press releases, the company said that at the moment a unique camera is being developed in its laboratories, the design of which does not use lenses at all. Moreover, this camera first takes a picture, and only then the user can adjust the focus of the image, as it was already implemented in the cameras of the manufacturer Lytro.
The press release of the Japanese manufacturer sheds light on how the future camera will work. Of course, some important nuances are not revealed to us, however, they explain that the technology is based on a special film with concentric circles applied to it, which covers the optical sensor. Because of this film, light falls on the surface of the sensor in a special way, which makes it possible to reconstruct an image using special algorithms. As for the focus, it can be done after the image is received. True, the developers immediately clarify that the focus will vary slightly less than it is implemented in the cameras of the manufacturer Lytro.
Of course, the quality of the final image will certainly be somewhat worse than that of traditional cameras using optics. But the goal of Hitachi is not to replace existing cameras at all. The manufacturer hopes that by reducing the size of the cameras, they can be embedded in places where it was simply impossible to imagine them before. For example, in the thin material of your clothes. It is the optics that today prevent further reduction in the size of the cameras, which is clearly seen in the latest models of iPhone smartphones, from the case of which the cameras stick outwards.
