Sony is going to be a three image sensors on the basis of the new ‘stacked’sensor technology release under the name of Exmor RS. The new light-sensitive cmos sensors are designed for smartphones and tablets.
Two of the three Exmor RS image sensors, “IMX135” and the “IMX134′, have both an rgbw structure, a white subpixel for a higher photosensitivity, as a built-in hdr movie feature. The IMX135 is a 1/3.06 model with 13,13 megapixels, while the IMX134 of the 1/4″type, with 8,08 megapixel. Also Sony releases a variant of the IMX134 without the rgbw structure, and hdr movie-option with the type ISX014.
The pixel size amounts to the three new sensors, designed for smartphones and tablets, 1,12 µm. Because of the addition of the white subpixel and the increase of the so-called aperture, the ratio between the photosensitive part and the total surface area of a pixel, claims Sony, and the light sensitivity of the pixels of the three Exmor RS sensors to current sensors with a pixel size of 1.4 µm. For comparison; an aps-c image sensor with 16 megapixels has a pixel size of roughly 4,8 µm.
Sony has the aperture increased by making use of its new stacked sensor technology. This is the hardware for the signal processing in a layer directly below the light-sensitive surface of the fotodiodes.
Sony announced in January this year, the new image sensors, but the company was still not flush with details of the stacked-image sensors. In June of this year, let the company know of extra to invest in the production of such sensors.
The new Exmor RS sensors will be starting in October, both loose and in a module, is supplied directly to be processed into end products. The IU135F3-Z-module with IMX135 sensor gets an f/2,2 lens, while the IU134F9-Z-module, the need to have of the small dimensions 8,5×8,5×4,2mm. All three modules are equipped with auto focus.
