Selecting Image Quality, Resolution, and Compression (continued)

Setting resolution and compression

You can change the resolution and compressions settings for each of the four quality settings.

The resolution and compression settings for each quality setting can be adjusted within the following ranges.

Quality

Resolution

Images created from pictures taken with a digital camera are composed of vertical and horizontal colored dots called pixels. In the notation 2240 x 1680, for example, 2240 is the number of horizontal pixels and 1680 is the number of vertical pixels. The greater the number of pixels in an image, the finer the quality and the larger the file size. Please remember that high quality images require more storage space on a memory card, thus reducing the number of images that can be stored on the card. Select as high a resolution as possible if you intend to trim the image, or enlarge the image larger than standard service size for printing.

Compression

The compression rate denotes the amount of JPEG compression. The higher the compression rate, the smaller the file size. However, the higher the compression rate, the more the image could deteriorate. With compression rates below 1:8 the amount of image deterioration is not noticeable, but if you are concerned about image quality then select a smaller compression rate like 1:4 or 1:2.7. The effect of the selected rate of compression could vary with the content of the image. These numbers provide only a general scale for reference and are not precise measurements.

The table below describes the relationship between resolution, compression and approximate file size.

Note

Less time is required to store smaller files on a memory card, with the exception of the 640 x 480 (VGA) selection which could require more time for compression as the file is saved.
