But Pill cam still has some room for improvements. The pill cam has four disadvantages and limitations. The first limitation is the inability to control the device. Just like an ordinary medicinal capsule, the endoscope capsule can be uncontrollable once it enters the human body. The camera may come up with blurred images and distortion as it may move either too fast or too slow while examining a certain area. Due to this limitation, there can be a failure on the path that the capsule can tackle. Also, it can go to unwanted directions and cause inaccuracy on the diagnosis or medication of the patient [4]. The second disadvantage is its size. The pill cam measures about 1.5 inches long and it is relatively huge and hard to swallow, especially for young patients that cannot swallow huge capsules. Due to this disadvantage, people who can swallow huge capsules are the only ones capable of taking this medication. Young and elderly patients can find it hard to swallow the pill cam. The third limitation is an object obstruction that can block the path of the pill cam. The third disadvantage is fecal matters that might block the shots captured by the pill cam. Due to this, the lens of the camera might be blocked by dirt and the outcome would be that the dirty lens would spoil the shots much of the way through [3]. The fourth limitation is it cannot enter on narrow areas. Meaning, clogging …show more content…
It is compose of non-toxic materials to avoid malignancy as it enters the human body. The wireless system is used to control the pill cam as it enter and exit the body of the patient. Through these characteristics, limitations have been generated. Since the pill camera is a wireless device as controlled by the Arduino microcontroller, the distance can the transmitter and receiver can communicate with each other is limited. Pill cam is operated using batteries. Pill cam has a life span and it can only stay inside the body on a certain span time. The pill cam is expensive because the materials used like color sensors, high definition camera, Arduino microcontroller, transmitter and receiver is today’s generation trend of
