摘要： A method is disclosed of reading an image data from an optical record carrier with a visually detectable pattern comprising a visually detectable pattern of pixels comprising at least one pattern element comprising an area of size s1 with a relatively low value v1 for an optical property and an area with size s2 with a relatively high value v2 for said optical property, wherein the data representative for a structure of the visually detectable pattern is embedded by variations in one or more of the parameters s1, v1, s2, v2 of the pattern elements. The method comprising the steps of scanning the visually detectable pattern and generating a detection signal representative for a visual property of the pattern as a function of position, retrieving the image data from the signal, retrieving an embedded data from the signal, generating an address data using said embedded data, storing image data values at addresses indicated by said address data.

摘要： A method of applying image data as a visually detectable pattern with at least one embedded data element at an optical record carrier is disclosed, comprising the step of physically mapping at least one channel symbol onto the record carrier, the channel symbol being selected from a set of mutually different channel symbols, the channel symbols each comprising an area of size s1 with a relatively low value v1 for an optical property and an area with size s2 with a relatively high value v2 for said optical property, the channel symbols being distributed over a plurality of subsets each having a plurality of channel symbols wherein the plurality of channel symbols within a subset have a distance that is substantially less than the distance between channel symbols of mutually different subsets, wherein the distance between two channel symbols is defined as the absolute difference between the ratios s1/(s1+s2). wherein the step of selecting comprises the step of determining a subset on the basis of the image data to be mapped in the visually detectable pattern and selecting one symbol from that subset on the basis of the at least one data symbol to be mapped. The invention further includes an apparatus, and a record carrier.
