Formation of a 3d image using a lenticular structure

A customizing system for forming a 3D image using a lenticular structure comprising:

• a carrier layer on which is formed an arrangement of a plurality of sub-pixels of at least two different colors, each sub-pixel having a single color among said at least two different colors;
• and
• a lenticular array comprising convergent lenses placed facing the sub-pixel arrangement;
• the customizing system comprising:
• an inspecting unit configured to perform a visual inspection of the lenticular structure by viewing the sub-pixel arrangement through the lenticular array by means of an image-capturing apparatus, said visual inspection comprising the following steps for each among M different viewing directions relative to the lenticular array, M being an integer at least equal to 2:
• a1) positioning of the image-capturing apparatus in the viewing direction;
• a2) detecting sub-pixels viewable through the lenses in said viewing direction;
• a computing unit configured to determine, from the color of the sub-pixels detected in a2) for each viewing direction, grayscale levels to be generated to reveal, by way of the sub-pixel arrangement, M images viewable through the lenticular array in the M viewing directions, respectively;
• and
• a customizing unit configured to customize the sub-pixel arrangement by forming grayscale levels facing the sub-pixels in the carrier layer by focus of laser radiation through the lenses so as to reveal the M images viewable through the lenticular array in the M viewing directions, respectively, said M images collectively forming the 3D image.
