Sony is to compete against Canon and Nikon with its own entry into the 24x36mm imaging sensor market.

The company has announced that it is developing its own 24.81 megapixel, full frame CMOS offering.

The chip is claimed to output all pixels at 6.3fps with lower noise than other designs of similar pixel-pitch because of its Column-Parallel A/D Conversion Technique.

Sony explains that this design means that each column of photosites is given its own 12-bit analogue to Digital Converter.

The sensor, aimed at DSLRs, is expected to be in production by the end of the year.

Key features at a glance for Sony's new CMOS sensor:
- 35mm full size image sensor with 24.81 megapixels
- Column-Parallel A/D Conversion method
- High-speed digital output (12 channel parallel LVDS output)
- 12 bit-AD Converter on chip
- All-pixel scan mode: 6.3 fps
- Total number of pixels: 6236(H)x4124(W)
- Number of effective pixels: 6104(H)x4064(W)
- Chip size: 41.0mm(H)x31.9 mm(W)
