Before shooting a scene, a professional photographer adjusts focus,
exposure and white balance based on his or her experience. Nikons
Scene Recognition System represents a completely new concept whereby
the camera makes this series of judgments as if it were the photographers
Scene Recognition System furthers the use of Nikons 1,005-segment
RGB metering sensor (first introduced in the Nikon F5) to recognize
colors and light patterns that help the new cameras (currently
the D300 and D3) determine the subject and the type of scene being
photographed, before a picture is taken.
data provided by their 1,005-pixel RGB Matrix Meter, Nikons
new SRS provides more precise subject identification, optimizing
autofocus, exposure and white balance detection.
Focus: The system uses data from the 1,005-segment
RGB sensor to track a moving subject along the plane of direction
within the frame. Complementing the AF sensor data with the subject
tracking data calculated from the RGB sensor makes it possible
for the D300 and D3 to select focus with great speed and precision.
subject identification performance:
information from the 1,005-segment RGB sensor is used to identify
the background and any human subjects, and contributes to sharp
focus by detecting where the subject's face is positioned. Human
subjects are given higher priority when using Auto Area A.
Color Matrix Metering II algorithms:
metering data from the 1,005-segment RGB sensor is used to detect
the areas of highlights. The range of brightness to be reproduced
is calculated from the results of highlight analysis and more
precise exposure control can be acheived.
Light source inference uses subject distance information and integrated
pattern recognition to optimize auto white balance.
Scene Recognition System Interview
Mr. Hiroshi Takeuchi, "To achieve an even better technology
was a challenge the Scene Recognition System absolutely had to
There were plenty
of difficulties just to do that. First of all, since the development
process required us to undertake simulations showing how certain
types of image data we photographed could produce certain types
of output, we had to start by taking huge volumes of sample photos
to be used in the simulations."
