Abstract

PURPOSE: To improve blur preventing performance by combining a blur detector and a blur warning device which use photo sensor pairs.
CONSTITUTION: The CCD 13 which constitutes photo sensors SAiWSAi-2, SBiW SBi-2 is connected to a control circuit 23 via video amplifier 15, memories 17, 18, absolute value circuit 21, etc. A blur warning device 25 is connected to the control circuit 23. By receiving the imaging rays of the pupil-divided objective lens in separate photo sensor arrays, the image by the objective lens is captured as the phase difference of the photo sensor array outputs and the focus matching degree is detected from the phase differences of a pair of photo sensor array outputs at a certain time. Blurs are extracted from the directions in the phase changes of a pair of photo sensor arrays and when the blur detection amount exceeds the blur amount permitted by photographing conditions, the blur warning device 25 is operated.
