Abstract
The invention provides an image processing circuit having a capability of performing a reduction (resizing) process and an enlargement process on horizontal-scanning-line data inputted in synchronization with an input horizontal synchronization signal, and subsequently adjusting the horizontal synchronization signals so that the input horizontal-scanning-line data is made transferable to external devices in real time, and an image processing method therefor. A reducing unit thins out n-lines of the input horizontal synchronization signals out of m-lines of the input horizontal synchronization signals HD. When an enlarging unit enlarges the image data by an enlargement ratio k (k: natural number) in the vertical direction, the enlarging unit inserts (k−1) lines of the second horizontal synchronization signals for data transmission EHSYNCin the transmitting horizontal-synchronization-signal interval time TCbetween adjacent first horizontal synchronization signals for data. transmission EHSYNCwith predetermined intervals. A composing unit merges the first horizontal synchronization signals for data transmission EHSYNCand the second horizontal synchronization signals for data transmission EHSYNCto give horizontal synchronization signals for data transmission EHSYNC.
