8-4 ER1 User Guide
software default is configured for the camera that ships with your robot. You should
only need to adjust this if you replace the default camera with one of your own.
Resolution
This box allows you to set the resolution of the camera. If you chose the Default option in
the Device box, the current resolution will be selected.
Remote Transmission
Another useful feature is a checkbox which lets you individually turn on/off each
camera's view under remote control. The checkbox is labeled Transmit this camera's
view under remote control. This setting is on the Camera tab, rather than the Remote
Control tab, for several reasons, including that it is a "per camera" setting and that it is
mirrored across the network under remote control (whereas the Remote Control tab is
not).
• Full resolution - This parameter specifies to transmit the camera feed at full
resolution. Note that even if this value is set, the image may still be scaled. This
occurs because the RCC’s display window is a 240 x 180 image. If you camera’s
resolution is higher than this, the extra pixels above this value are not used, so they
are not transmitted. Remember, the higher the number of pixels, the slower the
transmission and processing, but the higher the quality of the picture.
• 1/2 resolution - This parameter specifies to transmit half of the columns and half of
the rows of captured pixels.
• 1/4 resolution - This parameter specifies to transmit a quarter of the columns and a
quarter of the rows of the captured pixels.
• Use JPEG compression - This parameter specifies whether to use JPEG
compression. Compressing the images allows them to be sent more quickly, but it
has a negative effect on the quality of the camera images. Also note that JPEG
compression uses more CPU time to compress the images, so if you have a fast
connection, you may get better frame rates from the robot by not using
compression.
• Quality - This parameter allows you to specify the percent of the optimal
possible quality at which to save the video file. Specifying a higher value will
yield higher resolution and selecting a smaller value will yield lower resolution.
Valid values are 0-100. The default value is 85.
• Smoothing - One of the side effects of JPEG compression is jagged edges. This
parameter allows you to correct for that. Valid values are 0 to 100. The default
is 0.
