Symptom Cause/Remedy
The computer does not
recognise my camera.
When shooting a bright
subject on a dark
background, the image on the
display shows vertical stripes
radiating from the subject.
The image shown in the
finder of commercially
available software, etc. is
grainy.
Still pictures or video clips
captured with your camera
appear grainy on the display.
When commercially available
application software is used
to capture moving pictures
from your camera, some
frames are lost and the sound
falls out.
Black images are captured
when moving pictures or still
pictures are captured.
The images from your
camera freeze for several
seconds.
The images from the camera
are not displayed.
• When your camera is connected via USB hub, sufficient
power is not supplied from the hub.
t Use a USB hub capable of supplying 500 mA for each port.
This phenomenon is called “smear”. It is not a malfunction.
When a fast moving subject is shown in the finder, step-like
features in horizontal direction may appear, or horizontal stripes
may appear in moving parts. However this is not a malfunction.
• Images shot under fluorescent light may contain light
reflections.
• If the captured image contains dark parts, red or green noise
sometimes appears.
• The lens is dirty.
t Clean the lens.
• The lens is out of focus.
t Adjust the focus using the focus ring.
• When multiple applications are running, the processing
capacity of the computer may be exceeded. Close applications
not used.
• The computer’s power management function is activated.
t Check the CPU speed setting. For details on settings, see
the instruction manual for the computer.
Black images are captured temporarily during software startup
or immediately after the image size is changed.
t Capture the desired image after it is displayed.
In the following instances, the images may freeze for several
seconds. This is not a malfunction.
• When a keyboard short cut operation involving Fn keys is
performed.
• When the load on the CPU is heavy.
• Multiple application software programs for capturing images
are running simultaneously.
t Close all but one of the applications.
• Video memory has become insufficient due to the computer’s
image mode or number of colours, or as a result of other
circumstances.
t Lower the resolution or reduce the number of colours.
• If the images from the camera do not appear even after
performing the above steps, restart the computer.
