Patent number: 5099262Abstract: A camera has a function of recording sounds as well as recording images. In this camera, in a self mode in which photographing is executed using a self timer, sounds are recorded during counting of the self timer and in a usual photographing mode in which no self timer is used, sounds are recorded after completion of the photographing. These two modes are changed over automatically according to a selection of one mode.
