“Yes. It is correct to say that this is an epoch-making technology that has changed in a fundamental way the usual thinking about cameras. While 3D color matrix metering has vastly improved exposure accuracy with information obtained from the sensor, in the Scene Recognition System the recognition of various other elements beyond brightness has been improved to a level close to that of the human brain. The idea with the Scene Recognition System is that complex judgments that photographers make while viewing the subject through the viewfinder, such as “What is coming into the photo here?” or “How is the subject moving?”, can now to some extent be left up to the camera. “Until now, we have been improving AE, AF, and AWB technologies independently, but when these technologies matured, there was no technology capable of linking them. The Scene Recognition System is thus a core technology that links the superior aspects of these three technologies. It is second nature for professional photographers in particular to make detailed calculations in their head concerning exposure, focusing, and white balance based on experience, but color and brightness information captured by the 1,005-pixel RGB sensor provides support for these complex calculations.”
Isn't the diffraction grating a major point in the hardware that supports the ability of the Scene Recognition System to make judgments closer to those made by the brain of a professional photographer?
“Yes, at first glance, the diffraction grating only looks like a small plastic plate, but the zigzags you see here are actually very important. The diffraction grating is a special filter with a minute, nanometer-order structure. It diffracts light into red, green and blue, and radiates it more appropriately to the 1,005-pixel RGB sensor. By more fully bringing out the capabilities of the sensor, the light that has been separated into red, green and blue is reproduced in more vivid colors, allowing high-grade calculation of information for AE, AF, and AWB. Since the calculation process itself is a technology that combines various types of information, the calculations are of an extremely large scale. The development behind the Scene Recognition System could thus be described as a synthesis of advanced optical technologies and data processing technologies.”
