1.2 Image recording and processing

１）Image processing by DIGIC II
As with the EOS-1Ds Mark II, high-speed and high-quality image processing is executed
by DIGIC II (Fig. 004). Also, DIGIC II and the DDR SDRAM (EOS 20D: SDR SDRAM) buffer
memory work together to attain a continuous shooting speed of approx. 3 fps and a
maximum burst of 60 shots (Large/Fine).

２）Picture Styles
Picture Styles consolidate the processing
parameters and color matrix settings and take it
a step further. It is a new feature enabling even
the beginner digital photographer to select preset
settings which match his or her photographic
preferences to obtain the desired image effect (Fig.
005).
The basic elements for image creation, including
the color tone, color saturation, sharpness, and
contrast, are set differently to obtain a specific
photographic effect. For example, the "Landscape"
Picture Style tweaks the color tones and saturation
for blue skies and green trees to make the image look
more impressive. Also, the "Faithful" Picture Style,
which is the same as Digital Photo Professional's
Faithful setting of RAW image Editing, obtains a
colormetric and natural color reproduction even with
JPEG images.
Each Picture Style allows the user to adjust the
sharpness by 8 levels (0 to 7), and contrast, color
tone and color saturation by 9 levels (-4 to +4) (Fig.
006).
