Scalar is basic, but essential image signal processing. There are several well known techniques, like nearest neighbor, bilinear, bicubic. For hardware implementation, the algorithm and line buffer cost must be in consideration. 

    TITC develops a novel method, that the picture quality is close to bicubic with hardware cost effective. Besides, it can also equip with edge enhancement to get higher contrast. One of applications is power saving mode in mobile phone. The AP just transmits low resolution sequences and the sequences will be scaled up to resize the panel resolution in DDI. Therefore, the transition power can be reduced.
