Sony applied for a patent about Honeycom Image Sensor. It is not normal the Honeycom. Because Sony made a device on an electronic circuit, it can expect low cost and number of the pixels increase.

• Patent Publication No. 2010-161200
  • published 2010/07/22
  • filled 2009/01/08
• A square matrix imager of the conventional
  • 78.5% slight filling factor
    • 90.7% in the case of a honeycom
  • It has bad resolution of the diagonal course
    • Slippages is different from XY in the distance of the pixel/li>
    • Distance of the pixel is equal with all courses in the case of a honeycom
• A honeycom imager of the conventional
  • There is much number of the transistors
  • High cost
• A honeycom imager of the Sony's patent
  • There is little number of the transistors
    • Low cost
    • It can increase the number of the pixels
    • Good sensitivity
  • It assumes seven pixels one unit
  • It shares a transistor with seven pixels, and it reduces transistors

In fact, there was already omen. Sony α900 and α850 or others adopts 40-Segment Multi-Pattern Metering. Sony will have already had technology about the honeycom.

Speaking of a honeycom CCD or CMOS, the Super CCD Honeycom EXR of Fujifilm is famous. As for the merit of honeycom, form of a pixel is almost a circle. They which formed a line are equal in an interval. Because the conventional pixel was a square, the space of the slippage direction was large and harmed a feeling of definition.

I want Sony competes with Fujifilm and to make a better product.
