TECHNICAL INFORMATION
䡵 Normal (Field) Mode
During normal recording, the CCD’s storage time is approx. 1/60 sec. [U Ver.] or 1/50 sec. [E Ver.] in the field mode. With the odd
number fields, the total electric charge of the odd number lines and even number lines of the CCD are output to the odd number line
(reading two lines at a time), with the even number field, they are output to the even number line.

䡵 High Resolution (Frame strage) Mode (Reading every line)
The CCD storage time is approx. 1/30 sec. [U Ver.] or 1/25 sec. [E Ver.] with the High Resolution mode, which is twice that of the
Normal mode. However there is approx. 1/60 sec. [U Ver.] or
1/50 sec. [E Ver.] (one field) difference in the output timings between
odd number line and even number line. With the odd number fields, electric charge of the odd number line is only output to the odd
number line, and with the even fields, the electric charge of even lines is only output to the even number line. When recording
frames, still picture can be shot at all lines by combining with a FLASH.
With this mode, the vertical resolution is improved however, after-image lag will increase compared to that of the normal mode.
