Abstract
A scaling device and a scaling method that employs a pre-filter. Using a pre-filter instead of a post-filter and a data storage unit as in a conventional device, scaling quality of the device is improved and production cost of the device is reduced. The scaling device includes a pre-filter for receiving data columns and carrying out chromatic adjustment and a scaling process for receiving the adjusted data and producing scaled data.
Claims6
A scaling device, comprising:
- a pre-filter for receiving N data columns and outputting data after chromatic adjustment, wherein each of the N data columns includes M data sets, where M and N are a positive integers;
- and
- a scaling processor coupled to the pre-filter for receiving output data from the pre-filter and generating scaled data.
A scaling method that employs a pre-filter for chromatic adjustment, comprising the:
- the pre-filter receives N data columns and generates P data columns of enhanced or reduced columns after chromatic adjustment;
- and
- a scaling processor receives the P data columns and generates scaled data;
- wherein each of the N data column includes M factors, where 1<P≦N and P, M and N are positive integers.
