NTT DoCoMo, Inc. will launch the "FOMA N902i," a mobile phone with a camera equipped with a still image stabilizer on November 18, 2005. The handset is developed and manufactured by NEC Corp. Although the effective pixel count of the image sensor is about two million, the camera may provide a 4-megapixel still image resolution by using pixel interpolation. While most digital cameras use an optical image stabilizer which moves the lens mechanically, this camera employs an electronic image stabilizer.
More specifically, a still image is corrected for blur correction using the following steps: First, four still images are shot within the exposure time that other existing cameras require to shoot one image. Although each of the four images lacks exposure, image blur caused by camera shake is reduced since the shutter speed becomes faster. In the subsequent step, the four images are superimposed after feature extraction processing is carried out for each image. Based on the results of the processing, images are superimposed so as not to offset each other. Sony Corp. previously released the QUALIA branded "Q016-WE1" which used this method.
