8. 24 Long time exposure Frame accumulation Important notes on using this mode e Exposure time range is 1 30 sec to However it is recommended not to use exposure over 2 0 sec This is because visible dark current noise may appear on the video signal due to the long time exposure of the CCD image sensor e Ext HD signal TTL 2 0 5 0V has to be input continuously e See Fig 16 for the phase relationship between ext HD and ext VD pulses e The EEN pulse is not provided when using this mode 15 CV A50 IR 6 9 Start Stop Mode The exposure time is controlled by the interval between the ext trigger and the ext VD signal The exposure starts at the first HD pulse after the falling edge of the ext trigger and stops 14 5 H after the falling edge of the VD pulse It means that the trigger pulse must be applied after the external VD pulse for exposures less than 14 5 H The range can be between 1 60 to 1 10 000 for EIA and 1 50 to 1 10 000 for CCIR The Start Stop mode is a continuous mode where the VD signal must be given continuously It is not possible to input external VD randomly The difference between interlaced frame accumulation or field accumulation can be explained as follow Both modes have 2 fields output in an interlaced frame With frame accumulation the contents in the ODD and EVEN sync fields will come from sensing field 1 and 2 on the CCD sensor With field accumulation both ODD and EVEN sync fields will contai
