✦ Synopsis
A prototype of a vision system for capsular endoscopy provided with autofocus function was developed. It is composed by two main parts: a wireless capsule with an adjustable focus in the range between 15 mm and 100 mm, and a personal computer where the autofocus algorithm is implemented. Several benches and ex vivo tests were performed in order to validate the developed system and encouraging results were obtained. Further miniaturization will be pursued to obtain a swallowable device adequate for capsular endoscopy procedures.
