摘要： An address exchanger and a data exchanger are provided at both sides of a plurality of look-up tables (LUTs). An even number address is constantly accessed at one of the LUTs and an odd number address is constantly accessed in the other LUTs. An interpolating operation on the basis of values output from the respective LUTs may constantly cause the same results as can be obtained without address exchange. By this, for the memory to be accessed by the odd number address and the even number address, a grid point data for other transformation characteristics may be stored. Therefore, in the data transformation apparatus performing data transformation through interpolation employing a plurality of LUTs, memories of respective LUTs can be efficiently used for permitting data transformation of a plurality of kinds of transformation characteristics.

摘要： An image signal processing apparatus inputs a video signal, delays it by one field using a field memory, multiplies the delayed signal by a value K (K less than 1), adds the output from the multiplication to the input signal and supplies the sum to the field memory. The level of the signal read out from the field memory is compared with a predetermined value, and based on the result of that comparison, the video signal being input is substantially inhibited from being supplied to the adding means. The signal obtained by multiplying the immediately-preceding field signal by k, and the present-field signal, are cyclically added, so that the amplitude can be gradually increased. The comparison inhibits addition of a new field signal when the level of that stored in the field memory has reached a predetermined level.
