Image Quality and Compression

The process of reducing the file size of a picture when storing it is called compression. In this camera, pictures are compressed and recorded as JPEG files.

•The more a picture is compressed, the smaller the picture size becomes and the larger the num- ber of pictures that can be stored in memory or on a memory card. However, the quality of the image is degraded and the reproducibility of the image’s fine areas is reduced.

•The less a picture is compressed, the larger the picture size becomes and the smaller the number of pictures that can be stored in memory or on a memory card. However, it maintains the pre- sentation of the image’s fine areas and increases the image quality.

Image Quality Setting

Image quality can be also selected in the Assist modes ( 30) or Scene modes ( 36).
