Latest Patents

Imai’s listed patents describe techniques for improving the presentation of interlaced video on display devices.

One image display system converts input video signals by increasing the number of horizontal scanning lines by at least a factor of two. It generates alternating first and second fields, each containing effective and ineffective scanning lines arranged alternately. The display control aligns the effective lines in one field with the ineffective lines in the other, and vice versa, as the fields are displayed in turn.

Another image display system uses memory to store at least one scanning line of an interlaced video signal. It reads each line repeatedly at a speed that is an integer multiple of the writing speed, then pauses for the remainder of the horizontal scanning period. Successive fields are arranged to interpolate one another’s reading pauses.
