PURPOSE:To decide a normal or laterally turned position of an image by obtaining the characteristic values of image signal levels of belt-shaped areas extending in the vertical and horizontal directions from those image signals forming image information on a human body and comparing said characteristic values with each other. CONSTITUTION:A belt-shaped area 4 includes many peripheral areas 2 and a slight part of a human body 1. Therefore, the total synthetic value of the image signal levels is larger in the area 4 than an area 3 as long as the sizes of both areas 3 and 4 are approximately equal to each other. Then both total synthetic values are compared with each other and it is decided that the image 1 is set at a normal position as long as the area having the larger value is extended horizontally. While the laterally turned position of the image 1 is decided if said area is extended vertically. |
