Phenomena specific to CMOS image sensors

The following phenomena that may appear in images are specific to CMOS (Complementary Metal Oxide Semiconductor) image sensors. They do not indicate malfunctions.

White flecks

Although the CMOS image sensors are produced with high-precision technologies, fine white flecks may be generated on the screen in rare cases, caused by cosmic rays, etc.

This is related to the principle of CMOS image sensors and is not a malfunction.

The white flecks especially tend to be seen in the following cases:

when operating at a high environmental temperature

when you have raised the master gain (sensitivity)

when operating in Slow-Shutter mode

Aliasing

When fine patterns, stripes, or lines are shot, they may appear jagged or flicker.

Flicker

If recording is made under lighting produced by discharge tubes, such as fluorescent, sodium, or mercury-vapor lamps, the screen may flicker, colors may vary, or horizontal stripes may appear distorted. In such cases, turn the Flicker- Reduction function on (see page 51).

In some cases, such phenomena may not be improved with the Flicker-Reduction function. It is recommend to set the electronic shutter speed

to 1/100 sec. in 50-Hz areas and to 1/60 in 60-Hz areas.

Focal plane

Owing to the characteristics of the pickup elements (CMOS sensors) for reading video signals, subjects that quickly move across the screen may appear slightly skewed.

Formats and Limitations of Outputs

Video Formats and OutputFormats

The format of output signals from the COMPONENT OUT connector and the SDI OUT connector varies according to the recording/ playback video formats and the kind of the output signal (the setting of “YPbPr/SDI Out Select” of the VIDEO SET menu).

Output formats in E-E mode1)/recording mode (Camera mode)

Analog component signals from the COMPONENT OUT connector are output in the format shown below according to the “Video Format” setting of the OTHERS menu and the “YPbPr/SDI Out Select” setting (HD or SD) of the VIDEO SET menu.

The SDI OUT connector outputs serial digital signals of the same format converted from the analog component signals fed from the COMPONENT OUT connector.

1)E-E mode: Recording standby status

Note

No signal is output from the A/V OUT connector when “YPbPr/SDI Out Select” of the VIDEO SET menu is set to “HD” or “SD.”
