LED image display system with rigid frames positioned in at least one vertical stack forming a planar vertical display, with vertical rigid bar members mounted to each of the frames and with equal spacing, and LED pixels mounted to each bar member. The pixels are equally spaced apart forming a matrix of pixels that project colored light beams. A rod bearing weight of the frames in tension is connected to each of the frames, and the rods have top and bottom connectors. Top connector of top frame is removably secured to an overhead support while bottom frame is spaced from stage or other surface. Bottom ring connector of weight-bearing rod of each stacked frame is removably connected to top hook connector of each below stacked frame. Each weight-bearing rod includes rod portions threadably connected to a turnbuckle for tightly positioning all adjoining frames of the stack; and system includes controls receiving video signals and processing same as either still color images and/or color animated images.

The data conversion circuit according to claim 4, further comprising: an overflow preventing part for inputting said upper bit data of said input data before subjecting to addition by said adder as said second table input data to said look-up table storage memory when the first table input data inputted to said adder and said look-up table storage memory is the maximum value, thereby preventing overflow of said second table input data. 12. The data conversion circuit according to claim 1, wherein said look-up table for conversion has input/output characteristic data for performing γ conversion of image data. 13. The data conversion circuit according to claim 2, wherein said look-up table for conversion has input/output characteristic data for performing γ conversion of image data. 14. The data conversion circuit according to claim 4, wherein said look-up table for conversion has input/output characteristic data for performing γ conversion of image data. 15. The data conversion circuit according to claim 5, wherein said look-up table for conversion has input/output characteristic data for performing γ conversion of image data. 16. A data conversion method for converting intended input data into output data using a look-up table for conversion, the look-up table being stored in a look-up table storage memory and defining correspondences between input and output, the data conversion method comprising the following steps: a first step of adding "1" to first table input data which is upper bit data having a bit length corresponding to an input format of said look-up table for conversion among said input data by a predetermined adding process, to yield second table input data; a second step of outputting from said look-up table storage memory, first table output data associated with said first table input data using the look-up table for conversion, as well as outputting, from said look-up table storage memory, second table output data associated with said second table input data using the same said look-up table for conversion; and a third step of performing a weighting operation on said first table output data and said second table output data based on lower bit data excluding said predetermined bit number of upper bit data among said input data by a predetermined weighting process, interpolating between each of said table output data, and calculating output data having a bit length which is longer than that of said first table output data and said second table output data, wherein said look-up table storage memory is a dual port memory to which said first table input data and said second table input data are inputted simultaneously, and from which said first table outpu
