Glossary OIS (Optical Image Stabilization) This feature compensates in real-time for shaking and vibrating while shooting. There is no image degradation compared to Digital Image Stabilization feature. Optical zoom This is a general zoom which can enlarge images with a lens and does not deteriorate quality of images. Quality An expression of the rate of compression used in a digital image. Higher quality images have a lower rate of compression, which usually results in a larger file size. Resolution The number of pixels present in a digital image. High resolution images contain more pixels and typically show more detail than low resolution images. Shutter speed Shutter speed refers to the amount of time it takes to open and close the shutter, and it is an important factor in the brightness of a photo, as it controls the amount of light which passes through the aperture before it reaches the image sensor. A fast shutter speed allows less time to let light in and the photo becomes darker and more easily freezes subjects in motion. Vignetting A reduction of an image's brightness or saturation at the periphery (outer edges) compared to the center of the image. Vignetting can draw interest to subjects positioned in the center of an image. White balance (color balance) An adjustment of the intensities of colors (typically the primary colors red, green, and blue), in an image. The goal of adjusting the white balance, or color balance, is to correctly render the colors in an image. Appendixes 148
