| titleOfInvention | Endoscope imaging apparatus for both the NTSC and PAL systems |
| abstract | An endoscope imaging device is provided which can reduce flicker on a screen, such as occurs when a signal is converted from one television system to another, and which also makes it possible to standardize processor circuits that perform processing for different systems . The device has an oscillator (17) according to the NTSC system and an oscillator (18) according to the PAL system with an oscillation frequency of N È fh¶2¶ and a switching stage (19) for selecting one in an endoscope that is provided with a CCD (1) for the number of scanning lines z. B. is suitable according to the NTSC system, and it controls the CCD based on a timing signal generated in the selected oscillator. That is, when the PAL system is selected, image data are extracted from the CCD using a horizontal synchronizing signal with a frequency of 15.625 kHz (fh¶2¶), with the writing and. In a memory section (24) on the processor side the reading out of the image data is also carried out by means of a horizontal synchronization signal with this frequency fh¶2¶, which is why the difference between the writing speed and the reading speed becomes small, so that flickering on a screen is restricted. |
