Sony Corp announced that it developed a full-frame 35mm (diagonal: 43.3mm) CMOS sensor (image sensor) with an effective pixel count of about 24.81 million.
The pixel size of the sensor is 5.94 × 5.94µm. And its read speed is 6.3 frames per second when it reads all the pixels in 12-bit color. The sensor is targeted at digital SLR (single-lens reflex) cameras. Sony will begin commercial production of it within 2008.
The total pixel count of the CMOS sensor is about 25.72 million.
"(The count) was realized by manufacturing technologies, such as an advanced planarization technique to enhance the uniformity, in addition to self-developed circuit design techniques," Sony said.
The company used "Column-Parallel A/D Conversion Technique," where an A/D converter is arranged in parallel in each column of pixels. This technique reduces deterioration of picture quality caused by noise inherent in analog transmission and enables to read signals at high speed.
