具有照相功能的手机提供了一个机会，通过对特定时期内所吃食物的自动成像来加强饮食回忆。为了探索捕获所有食物所需的成像频率，我们在一项自动成像的试点研究中检查了单个食物的图像数量，该研究使用相机手机设置为每10秒一次快照的图像捕获频率。食物图片来自10名年轻的成年受试者，他们在工作日连续佩戴手机并同意分享他们的图像。基于每次进食体验接收到的图像数量，试点数据表明，以每10秒一次的频率自动捕获图像足以记录正常用餐期间消耗的食物，而更高的成像频率则需要捕获快速食用的零食和饮料。美国饮食协会杂志2010;110：1238-1241。
Camera-enabled cell phones provide an opportunity to strengthen dietary recall through automated imaging of foods eaten during a specified period. To explore the frequency of imaging needed to capture all foods eaten, we examined the number of images of individual foods consumed in a pilot study of automated imaging using camera phones set to an image-capture frequency of one snapshot every 10 seconds. Food images were tallied from 10 young adult subjects who wore the phone continuously during the work day and consented to share their images. Based on the number of images received for each eating experience, the pilot data suggest that automated capturing of images at a frequency of once every 10 seconds is adequate for recording foods consumed during regular meals, whereas a greater frequency of imaging is necessary to capture snacks and beverages eaten quickly.
