Charged coupled devices appeared in the early 1970's and consist of an array of light sensitive cells arranged in a matrix etched on to a silicon chip. They were first used in astronomy applications in place of photographic plates that needed long exposure times of faint stars. They were very expensive arrays and the number of pixel elements was fairly small but,when coupled to a computer, were able to count photons and log them into a data set. This was not possible to do prior to this electronic photo plate. Kodak introduced the first digital camera in 1990 but I don't think it is possible to accurately tell what was the first. I would say a photo of a distant galaxy in about 1972 is a good guess.
