Aptina is offering has a new 1/3,2″-bsi-cmos image sensor for mobile phones released. The AR0833 sensor has 8 megapixels and makes a higher quality video is possible because of the compression, no image information is lost.
In current image sensors for mobile phones uses subsampling or pixelbinning to data for video read-out. In the first method, only information of the video resolution required pixels spread across the sensor, read. This can lead to image defects as rough edges and leading to color faults. At pixelbinning is the loading of different photodiodes are merged into a single, lichtgevoeligere pixel. Also with this technology, can image defects occur.
Aptina is offering grabs it with his new AR0833 image sensor otherwise. It is possible to image with the full resolution of the sensor at 30 frames per second can be read out. It is only a 16:9 crop for the video used. This is then downsampled to the final resolution of up to full hd. Because prior to the compression, no image information is lost, can a higher quality video to be obtained. An additional advantage is that with this method, the angle of view in video remains the same.
It is also possible to simultaneously full-hd video and a photo in the full sensor resolution to shoot. The same functionality is possible with the Nikon 1-series, which also features an aptina is offering image sensor. The manufacturer claims furthermore, the shutter lag time due to the switch between the preview mode with low resolution, and the image in the full sensor resolution to have taken away. In combination with an hdr image processing is also possible for the sensor with hdr photos and videos.
Aptina is offering at the AR0833-sensor use of his A-PixHS-pixeltechnologie with a pixel size of 1.4 µm. The 1/3,2″-sensor of the bsi-cmos type, and makes modules as possible, with a size of 8,5×8,5×5,9mm. Of the sensor, intended for smartphones and tablets, roles have now the first samples of the band, and with the mass production would be in the second quarter started.
