数码摄影和录像技术为研究动物行为提供了丰富的数据，因此成为广泛使用的技术。对于固定的，不移动的相机，有一个分辨率和视野的权衡，运动模糊在曝光过程中会在传感器上涂抹主体。虽然固定摄像机的这些基本权衡可以通过使用多个摄像机和提供额外的照明来避免，但这可能并不总是理想的。另一种方法可以克服固定摄像机的这些问题，那就是在动物移动时，将高倍率摄像机对准动物。在这里，我们回顾了自动跟踪用于在移动光路的工作体积中保持动物的系统。这样的方法提供了一个机会，以逃避分辨率和视野之间的权衡，也减少运动模糊，同时仍然启用自动图像采集。我们认为，进一步的发展将是有用的，并概述了可能改进技术并导致更广泛使用的潜在创新。
Digital photography and videography provide rich data for the study of animal behavior and are consequently widely used techniques. For fixed, unmoving cameras there is a resolution versus field-of-view tradeoff and motion blur smears the subject on the sensor during exposure. While these fundamental tradeoffs with stationary cameras can be sidestepped by employing multiple cameras and providing additional illumination, this may not always be desirable. An alternative that overcomes these issues of stationary cameras is to direct a high-magnification camera at an animal continually as it moves. Here, we review systems in which automatic tracking is used to maintain an animal in the working volume of a moving optical path. Such methods provide an opportunity to escape the tradeoff between resolution and field of view and also to reduce motion blur while still enabling automated image acquisition. We argue that further development will be useful and outline potential innovations that may improve the technology and lead to more widespread use.
