    摘要: An OSD device is provided which allows a reduction in the capacity of a memory for storing OSD data and also allows the efficient use of a transfer frequency band in the transfer of the OSD data. A management information data set MD includes, for the display position of each of OSD data sets OD to be superimposed on sensed image data sets SD, display position information sets HDISP and VDISP on the OSD data set OD and a storage location information set WORD on the OSD data set OD. The on-screen display device comprises an OSD data storage region (32) for storing the OSD data sets OD, senses the management information data set MD having HDISP and VDISP which match the display position of each of the sensed image data sets SD, and retrieves the OSD data sets stored in WORD included in the management information data set MD from the OSD data storage region (32).

    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.
