The early history of projectors and cameras goes as far back as 4th century BC. Naturally-occurring pinhole cameras were found during excavations in Ancient Greece. The idea was developed by Ibn al-Haytham in the 10th century. It was known in ancient China starting from the 5th century BC. The very first record of a device projecting an image onto a surface could be traced to 1420. In the 17th century the era of magic lanterns started.
However it was not until the end of the 19th century that movie projectors appeared. We should definitely mention British photographer Eadweard Muybridge and his Zoopraxiscope (1879), as well as Woodville Latham and his sons who demonstrated their Panopticon in 1895. First digital cinema projectors were tried in movie theatres in 1999, and today we can hardly imagine a movie theatre without this device.
Having a digital projector at home has a lot of benefits, but when the device breaks down, it is very disappointing. Luckily, most of the top-selling projectors manufactured by such brands as Panasonic, Hitachi , Sony, Optoma, Vivitek, BenQ, and Epson are rather reliable.
