Sony Develops 24.81-Megapixel Full-Size CMOS Image Sensor

Sony Corporation today announced the development of a full-size 35mm 24.81-megapixel (effective) CMOS image sensor designed for digital SLR cameras.

The newly developed CMOS image sensor combines unique circuit design technology with Sony's advanced fabrication expertise, such as advanced planarization for minimizing fluctuation, to realize 35mm, full size, 24.81 effective megapixel resolution. Sony's "Column-Parallel A/D Conversion Technique" also provides each column within the sensor with its own A/D converter, minimizing image degradation caused by the noise that arises during analog processing while at the same time delivering an extremely high signal conversion speed.

Sony will target for mass production of this CMOS image sensor within this year.

Features:

• "Column-Parallel A/D Conversion method":
  • CDS/PGA(24dB)Circuit (PGA: Programmable Gain Amplifier)
  • 12bit-AD Converter on chip
  • Diversified readout mode: all-pixel scan mode, 6.3 frame/s (12bit)
  • Window readout
• High-speed digital output (12 channel parallel LVDS output)

Device structure:

• Total number of pixels: 6236(H) x 4124(V) approx. 25.72M pixels
• Number of effective pixels: 6104(H) x 4064(V) approx.24.81M pixels
• Number of active pixels: 6096(H) x 4056(V) approx.24.73M pixels
• Chip size: 41.0mm (H) x 31.9 mm (V)
• Unit cell size 5.94µm (H) x 5.94µm (V)
