1) Image recording
(1) Large, single-plate CMOS sensor with approx. 8.20
megapixels
The newly-developed CMOS sensor has approx.
8.20 effective megapixels and an picture size of 22.5
mm
×
15.0 mm. (The focal length conversion factor
is 1.6
×
.)
(2) DIGIC II imaging engine
DIGIC II imaging engine for high-precision and
high-speed natural color reproduction.
(3) Better RAW+JPEG file handling
With the EOS 10D, dedicated software was
required to extract the JPEG file embedded in the
RAW file. But with the EOS 20D, the RAW and JPEG
images are saved as separate files in the CF card as
with the EOS-1D.
Also, as shown in Fig. 002, you can use the
menu's [Recording quality] to select the RAW+JPEG
option directly.
As with the EOS-1D Mark II, RAW files use a new
format indicated by the CR2 file extension.
(4) Complies to DCF 2.0 and Exif 2.21 supporting Adobe
RGB
The camera complies to DCF 2.0 and Exif 2.21, updated to support Adobe
RGB. When you use software compatible with Exif 2.21, images captured
with the EOS 20D will open automatically in the Adobe RGB color space.
Also, when you use a printer which complies to Exif 2.21, the printer will
suitably adjust the color saturation of the print.
(5) Faster writing to CF card
With DIGIC II and an improved CF card writing process, data writing is
about 3.5 times faster * than with the EOS 10D.
* With a Canon 512 MB (Super High-speed) CF card
2) Image Processing
(1) White balance feature
• White balance correction
This is a digital color filter that works like an LB
(light balancing) filter or cc (color compensating)
filter.
Both 1. Blue/amber bias and 2. Magenta/green
bias can be set up to ±9 levels.
