Abstract: A method of and an apparatus for inspecting a bottle or the like by which presence or absence of a defect, particularly of a check, can be determined with a high degree of accuracy.  Light is irradiated upon an inspection area of an object being rotated or moved, and reflected light is photographed by means of a two-dimensional camera which includes solid-state image pickup elements.  Picture element data for a first frame are fetched at a first point of time from the two-dimensional camera and stored into a memory, and then picture element data for a second frame are fetched at a second point of time after a fixed interval of time after the first point of time.  Then, differences of the picture element data for the second frame from the picture element data for the first frame from the memory are taken and binary digitized with reference to a predetermined brightness threshold level, and a number of those of the differences which have one of two binary values is counted.  The count number is compared with a predetermined number to determine presence or absence of a defect in the object for inspection.
