摘要： Vertical sync signal separation apparatus and method are provided. The vertical sync signal separation apparatus includes a parameter detecting unit, a threshold generating unit and a vertical sync signal generating unit. The parameter detecting unit measures a composite sync signal to obtain a maximum and a second maximum positive pulse width, and a maximum and a second maximum negative pulse width. The threshold generating unit outputs a positive pulse threshold based on the maximum and second maximum positive pulse width, and outputs a negative pulse threshold based on the maximum and second maximum negative pulse width. The vertical sync signal generating unit outputs a vertical sync signal by comparing the composite sync signal against the positive pulse threshold and the negative pulse threshold. As such, this apparatus can correctly separate a vertical sync signal from composite sync signals with different standards, thus increasing its supportability.

摘要： 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 EHSYNC2 in the transmitting horizontal-synchronization-signal interval time TC1 between adjacent first horizontal synchronization signals for data. transmission EHSYNC1 with predetermined intervals. A composing unit merges the first horizontal synchronization signals for data transmission EHSYNC1 and the second horizontal synchronization signals for data transmission EHSYNC2 to give horizontal synchronization signals for data transmission EHSYNC.
