Scene Recognition System

Nikon's Scene Recognition System (SRS) recognizes the position, color, tones and characteristics of a subject or overall scene prior to capture; then, using information from the 1,005-pixel RGB sensor, compares that information to the camera's built-in image database to achieve more accurate autofocus, auto exposure and auto white balance control.

The Scene Recognition System's accuracy and precision are made possible by the image recognition capability of the sensor. Data supplied to the camera's system by the RGB sensor includes subject tracking and identification, highlight analysis and light source identification.

Even changes of subject position within the viewfinder can be recognized as image information, and this capability is used by the autofocus system as a 3D-tracking function to give greater priority to the subject’s position. For subject tracking, the sensor recognizes the color of a subject within a user-selected focus point, then follows the subject’s movement by detecting the identical color segment. The 3D-tracking mode shifts the focus point automatically to respond to the subject’s movements. The AF and SRS are in constant communication with each other, improving tracking performance even for subjects quickly approaching the camera.             

As an auto white balance function, better image recognition combined with an advanced auto white balance algorithm achieves higher-performance white balance control.

For subject identification, the SRS uses color information from the sensor to automatically detect people and skin tones. In this way it can quickly focus on the most important element—the human face—in Auto area AF mode. Even if similar colors exist both in the foreground and background, the Scene Recognition System uses distance information from a D- or G-type AF NIKKOR lens to determine where the main subject is.
