Photo CD images are stored as a hierarchy of components ranging from Base/16 to 64Base which relate to the varying image resolutions that can be reconstructed. [27] The Base image, which has a luma resolution of 512 lines by 768 pixels, is typically used for the TV systems. The higher-resolution images are usually used for photographic imaging.
