2-3 High Image Quality
- 1/2.7-inch CCD with approximately 3.2 million camera effective pixels (total of about 3.3
million pixels)
The IXY DIGITAL 320 is equipped with a newly developed 1/2.7-inch 3.3 million pixel CCD (about 3.2 million
camera effective pixels). The pixel pitch of this CCD is 2.575mm by 2.575mm, achieving a huge 39 percent size
reduction in the area ratio of the chip when compared to conventional 1/1.8-inch three-megapixel-class CCDs
(found on the PowerShot G1/S30). Because of this, it is possible to appropriate the optical system and body of
the previous IXY DIGITAL 200a, resulting in an ultra-compact three-megapixel-class digital camera.
- High definition and fast processing with the newly developed “DIGIC (Digital Imaging Processor)”
The IXY DIGITAL 320 comes equipped with the “DIGIC (Digital Imaging Processor)”, a newly developed
image processor. DIGIC (Digital Imaging Processor) achieves enhanced high picture quality by improving
signal processing algorithms as the
successor of prior processor.
The following* are the main advances
of the DIGIC (Digital Imaging Processor).
• Improved picture quality
• Improved AF accuracy
• Improved processing speed
* The DIGIC (Digital Imaging Processor) features
many improvements, but the three
points above are the principle
contributions to the Ixy digital 320.
- VGA-size movies that achieve higher picture quality
The new 3-megapixel CCD of the IXY DIGITAL 320 can read 1 line of every 3 lines in the lengthwise
direction due to a change in the electrode structure (charge reading method). Because of this innovation, a
moving image with 524 lines per frame can be created resulting in a huge step forward in quality in comparison
to VGA-size movies of previous models (pixel interpolation* types).
However, with the increase in the number of CCD pixels, the frame rate is reduced to 15 frames per second
from the IXY DIGITAL 200a’s 20 frames per second.
