Optical assembly for television front screen

A television image processing device for use in front of a television screen having a diagonal dimension S, the image processing device comprising

• four panels connected together to form a hollow body having a substantially rectangular open front side of width W and height H and a substantially rectangular open rear side of width W' and height H', the separation between the front and rear open sides being D and the inner sides of the panels being reflective;
• and
• a front lens extending across the open front side of the body, wherein the dimensions are related according to the following formulae:
• (1) W=[1+(W'/H'-B)].multidot.W'
• (2) H=[1+(W'/H'-B)].multidot.H'
• (3) D=K.multidot.S
• Where:
• (i) B=(.sqroot.5-1)/2
• (ii) 0.1<K<0.2.

An image processing device for use in providing a three dimensional quality to an image generated by a television screen, the image processing device comprising a substantially rectangular box open at first and second ends, the first end being disposed adjacent to the television screen for receiving the image and the second end projecting the image outward, the substantially rectangular box having a diagonal dimension S, the first end substantially having a width W and height H and the second end substantially having a width W' and height H' a distance between the first and second ends being substantially D, wherein inner sidewalls of the substantially rectangular box are reflective, wherein S, H, W, W', H', and D are related according to the following:

• (1) W is substantially [1+(W'/H'-B)].multidot.W'
• (2) H is substantially [1+(W'/H'-B)].multidot.H'
• (3) D is substantially K.multidot.S
• Where:
• (i) B is substantially (.sqroot.5-1)/2
• (ii) 0.1<K<0.2.
