Conductive film manufacturing method, conductive film, and recording medium
Disclosed is a method for manufacturing a conductive film in which a mesh pattern comprising a wire material is provided on a base material. Also disclosed are a conductive film and a recording medium. Image data representing a mesh pattern is created on the basis of a plurality of selected positions. On the basis of said image data, an evaluation value which quantifies noise characteristics of the mesh pattern is computed. On the basis of the computed evaluation value and prescribed evaluation conditions, one image datum is chosen as an output image datum.
1. A conductive film having a mesh pattern formed by a process comprising: creating a plurality of polygonal meshes such that
a two-dimensional power spectrum of a centroid position distribution indicating each centroid position of the polygonal meshes forming the mesh pattern is given such that, when the most intense spatial frequency is defined as a standard spatial frequency, an average intensity in a spatial frequency band higher than standard spatial frequency is greater than an average intensity in a spatial frequency band lower than the standard spatial frequency.
2. The conductive film process according to claim 1 , wherein the standard spatial frequency is a spatial frequency at which a human visual response characteristic corresponds to 5% of a maximum response thereof.
3. The conductive film process according to claim 2 , wherein:
the human visual response characteristic is a visual response characteristic obtained based on a Dooley-Shaw function at a visibility distance of 300 mm; and
the standard spatial frequency is 6 cycle/mm.
4. A conductive film having a mesh pattern formed by a process comprising: creating a plurality of polygonal meshes such that
