Technology to drastically improve the image quality of cameras mounted on mobile phones Appears

While major mobile phone companies such as NTT DoCoMo, au and Softbank Mobile are launching mobile phones equipped with 12 million pixel cameras,In February this year NEC will announce LSI for mobile phones that supports 13 million pixel cameraAlthough I do not know where to increase the number of pixels for mobile phone cameras such as mobile phones, there is a limit to improving image quality by increasing the number of pixels.

Under such circumstances, a technology to dramatically improve the image quality of the camera with a new approach was announced.

Details are as below.
QuantumFilm Could Change the Way Your Camera Phone Takes Pictures

According to this article, the company called InVisage has developed a technology called "QuantumFilm" that dramatically improves the image quality of cameras installed in mobile phones.

Cellular phone cameras continue to increase in number of pixels, but as the number of pixels rises, it is said that more light is required for photography (= the picture becomes darker), so that the picture does not become dark It is necessary to increase the size of the CMOS sensor of the camera in order to acquire more light.

However, since it is a camera mounted on mobile phones, there are restrictions on the size, and it has been difficult to enlarge the CMOS sensor to match the improvement in the number of pixels, but "QuantumFilm" Without enlarging the sensor, it is said that succeeded in capturing the light which is four times as much as before.

This is the outline of "QuantumFilm" technology. The left is a conventional CMOS sensor and the right is a new CMOS sensor. With "QuantumFilm", CMOS sensors can capture twice the light compared to the conventional CMOS sensor, and by further doubling the efficiency of detecting light, it is now possible to capture four times the conventional light I will.


In addition, "QuantumFilm" is said to be able to apply the manufacturing process of conventional CMOS sensor, it is thought that it is going to be commercialized within 18 months after creating a prototype of the product in fall.
