Document Type and Number:
Japanese Patent JP4202383
Kind Code:
B2
Abstract:
A resolution conversion apparatus and method. The apparatus includes an image analysis unit analyzing frequency characteristics of an input image signal, a filter coefficient determination unit setting a filter coefficient according to the frequency characteristics, and a noise shaper unit performing noise shaping with respect to an error generated by quantizing the input image signal, according to the filter coefficient. Accordingly, an image can be naturally realized by performing noise shaping according to characteristics of the input image signal.
