Image pickup apparatus 201 generates the optical image formed with light from the image pickup optical system and the second image is generated by using the output from taking picture system 303 and the 2nd image-pickup element with which the first for display and record image is generated by using the output from the 1st image-pickup element 211 that converts the photoelectron respectively and the 2nd image-pickup element 208 and the 1st image-pickup element. Detection system 303 that searches for photometry and the object by using the second image is possessed. The detection system searches for the object when it can be selected whether to add the pixel of the output from the second image-pickup element in photometry, and doesn't add the pixel, and limits the object searching when the pixel is added.
