Abstract
A photographing lens focuses and forms incident light from a photographed body as an image on an image pickup face. An image pickup element photoelectrically converts the incident light focused and formed as an image by the photographing lens and converts the incident light to an image signal. A first control section obtains a first image signal by reading the image signal from each of pixels of a first area in all image pickup areas of the image pickup element. A second control section obtains a second image signal by reading the image signal from each of pixels of a second area smaller than the first area in all the image pickup areas of the image pickup element. A display section displays the first image signal obtained by the first control section. A third control section controls a level of the first image signal obtained by the first control section and a level of the second image signal obtained by the second control section such that these levels are substantially equal to each other.
