From website: Monochrome-Dedicated CMOS Image Sensor
To pursue the highest level of monochrome expression, a dedicated image sensor was developed. It does not use a color filter to acquire color information; instead, each pixel captures the brightness information of the subject and directly translates it into a monochrome image. This allows the sensor to receive more light information than a conventional color image sensor, resulting in sharper images with enhanced detail and improved sensitivity.
