Panasonic AG-MDC20GJ / AG-MDR25PJ AG-MDR25 Camera Recorder Operating Instructi - Page 245

Problem The subject is not brought into focus during zooming when the manual setting is used for the focus Cannot focus in the Infrared Recording Mode. The images appear jerky when 29.97p, 25.00p or 23.98p is selected. Something is wrong with the coloring of the pictures The pictures are too light or too dark The images are in black and white The auto white balance adjustment (AWB) does not work The screen is too bright in the Infrared Recording Mode. Iris cannot be operated in the Infrared Recording Mode. When fine lines or cyclical patterns are shot, flickering is seen or coloring is added to them Noise occurs in the audio input Check points ≥ First adjust the focus at the Tele end where the focusing accuracy is higher, and then proceed with the zooming. ≥ Under some operating conditions, it may be hard to bring subjects into focus. In such cases, use the focus at the auto setting (l 49, 138) ≥ Are you shooting in visible light? The focus position is different between the visible light and the infrared light due to difference in the refraction index. This unit assumes infrared light with wave length of approximately 850 nm for Infrared Recording Mode. Execute manual adjustment if necessary. (l 49, 138) ≥ This is normal operation. Images may appear somewhat jerky from time to time. ≥ Activate the ATW (Auto tracking white adjustment) function. (l 53) ≥ In some situations, the proper colors may not be reproduced using the ATW function. In cases like this, proceed with the white balance adjustment. (l 54) ≥ (When performing the operations using the controller) Perform menu setup and switch to ATW. [SW SETUP]→[WHITE BALANCE MODE]→[ATW] ≥ Use the ND filters to adjust light intensity. (l 81, 208) ≥ Either select the auto setting for the iris or select the manual setting and adjust the iris manually. (l 55, 208) ≥ Set [AUTO SHUTTER LIMIT] to [OFF]. (l 160, 210) (When performing the operations using the controller) ≥ Press the [AUTO] button for IRIS to switch to auto iris adjustment. ≥ Press the [AUTO] button for GAIN to switch to auto gain adjustment. ≥ Images may be output in black and white in Infrared Recording Mode. (l 70, 161) ≥ Is the [CHROMA LEVEL] set to a value close to the lower limit? (l 204) ≥ Auto White Balance (AWB) is not possible in the Infrared Recording Mode. (l 70, 161) ≥ The iris is set up to fully open in the Infrared Recording Mode to prevent camera voyeurism. Adjust the brightness with the light source. (l 70, 161) ≥ This phenomenon occurs because the pixels are arranged systematically on each image sensor. It is noticeable when the spatial frequency of a subject and the pixel pitch are brought into proximity so change the camera angle or take other such action. ≥ Confirm the following. j Are the Camera Head, the unit, the switching hub, or other peripheral devices grounded? j Are power lines are running nearby? j Is equipment generating strong electric or magnetic fields (e.g., television and radio antennas, air conditioning compressors, power transformers) located nearby? ≥ If the noise is not reduced via movement of surrounding devices, use a microphone equipped with an amplifier, or connect an audio output with low output impedance. - 245 -
