[Data Format]

・   Output signals of the image intensified CCD camera are recorded by a S-VHS recorder.  All the sprite images are captured digitally by a video A/D board from S-VHS tapes.

・   The sprite image data are sampled every one field (1/60 sec).

・   The resolution of the time superimposed on the image data is better than 10 msec.

・   The gain level of the CCD camera was manually adjusted (did not use the auto gain control).

・   The data format of the sprite image is bitmap (bmp) or jpeg (jpg).

・   The structure of the folders and file names are as follows,

YYYY       YYMMDD

              YYMMDD          hhmmssss

              hhmmssss         hhmmssss.bmp

                                     hhmmssss.jpg

> YYYY :         Year                                                                       (ex. 2004)

> YYMMDD :   Year(YY) + Month(MM) + Day(DD)                                   (ex. 040107)

> hhmmssss :   Hour(hh) + Minute(mm) + Sec., 100&10mili Sec.(ssss)         (ex. 13074441)

＜file＞

hhmmssss.bmp : Hour(hh) + Minute(mm) + Sec., 100&10mili Sec. (ssss)  (ex. 13074441.bmp)

hhmmssss.jpg : Hour(hh) + Minute(mm) + Sec., 100&10mili Sec. (ssss)   (ex. 13074441.jpg)

※ All the date and time are indicated by UT.

・   An field image consists of h=780 × v=480 pixels with 1-Byte RGB resolution.
