Approximate Values for Recording Pixels and Compression
Ratio (for 4:3 Aspect Ratios)
• The values in the table are measured according to Canon standards and may change
depending on the subject, memory card and camera settings.
• The values in the table are based on 4:3 aspect ratio. If the aspect ratio is changed
(p. 90), more images can be shot because the data size per image will be smaller than
with 4:3 images. However, since 16:9 images have a setting of 1920 x 1080 pixels,
their data size will be larger than 4:3 images.
