The script will take up to 100% CPU capacity. To slow down the script artificially, you can use [throttling](http://wiki.ros.org/topic_tools/throttle) of frames from the camera, for example, at 5 Hz (`main_camera.launch`):
> **Note** Starting from [image](image.md) version **0.24** `image_raw_throttled` topic is available without addition configuration.

Скрипт будет занимать 100% процессора. Для искусственного замедления работы скрипта можно запустить [throttling](http://wiki.ros.org/topic_tools/throttle) кадров с камеры, например, в 5 Гц (`main_camera.launch`):
