Predetermined quality settings for recording JPEG images in some digital cameras. JPEG images may be compressed at various quality levels, and the record modes are preset compression ratios for one or more resolutions. From low to high, they are "standard quality" (SQ), "high quality" (HQ) and "super high quality" (SHQ).
Some cameras may use these modes for TIFF images as well, in which case the mode refers only to resolution, not compression. These modes are not standard and represent different settings from camera to camera, and they may not be used at all. Following is an example of the modes from one camera, which also uses them for setting movie resolution and frame rate. See
