Abstract: A Pupillometer is disclosed. The Pupillometer has a display, an imaging apparatus that has a pupil finder and a microprocessor, and a memory in communication with the microprocessor. The display is sized to simultaneously display a video of y or more seconds in length of a left pupil and a video of y or more seconds in length of a right pupil. The pupil finder identifies the perimeter of a pupil. The imaging apparatus is capable of recording images of an individual's pupils at a rate of x image frames per second for a period of y or more seconds and playing back said image frames as a video at x image frames per second or at another rate that is faster or slower than x image frames per second. The memory has stored therein a program for enabling said microprocessor to do the following: (i) identify a center of the left pupil and a center of the right pupil for each image frame; (ii) synchronize each image frame of the two videos starting from the first frame; (iii) cause the display to display the two videos simultaneously such that each of the image frames of the video of the left eye is synchronized to a corresponding image frame of the video of the right eye when played back on the display; and (iv) cause the two videos to be displayed so that the center of the left pupil in each image frame is aligned on the display with the center of the right pupil for the corresponding image frame.

Abstract translation: 披露了一种瞳孔计 瞳孔计具有显示器，具有瞳孔取景器和微处理器的成像装置以及与微处理器通信的存储器。 显示器的大小可同时显示左瞳孔长度为y或更多秒的视频以及右瞳孔长度为y或更长秒的视频。 瞳孔探测器识别瞳孔的周长。 成像装置能够以y或更多秒的时间以每秒x个图像帧的速率记录个体瞳孔的图像，并且以每秒x个图像帧的速度再现所述图像帧，或以另外的速率 比每秒x个图像帧更快或更慢。 存储器中存储有用于使所述微处理器执行以下操作的程序：（i）为每个图像帧识别左瞳孔的中心和右瞳孔的中心; （ii）从第一帧开始同步两个视频的每个图像帧; （iii）使显示器同时显示两个视频，使得在显示器上播放时，左眼视频的每个图像帧与右眼视频的相应图像帧同步; 和（iv）使两个视频被显示，使得每个图像帧中的左瞳孔的中心与显示器对准用于相应图像帧的右瞳孔的中心。
