Abstract

A self-photographing method for an autofocus camera, wherein, upon depression of a shutter release button, the subject distance data are detected a plurality of times at periodic intervals, and a predetermined exposure operation, that is, an actual shutter release operation is automatically executed using the autofocus system when the detected subject distance data have changed from each other. The distance data are repeatedly detected and compared with each other until these distance data differ from each other. If the distance data have been equal for a predetermined time interval from the shutter release button depression, then the actual shutter release operation is executed, or is called off and the self-photographing is terminated. It is preferred that the detected change of distance be a decrease of distance, indicating that the photographer has stepped into the picture, whereupon the measured distance becomes his distance in place of the background distance.
