An image processing device comprises a reproducing part for reproducing an image signal from a recording medium, a printing part for printing on a recording material an image relative to the image signal reproduced from the recording medium, and a manual operating member. In response to an operation of the manual operating member, the reproducing part reproduces the image signal from the recording medium and the printing part prints out the image signal reproduced from the recording medium. The image processing device enables contents recorded on the recording medium to be checked by a minimum and simple operation in a short time.

An exposure control device for performing exposure control on the basis of a video signal obtained from a light measuring area set within an image sensing plane is provided with a determining circuit which determines the position of a photographed object within the image sensing plane from the values of a specific component of the video signal obtained from the inside and outside of a detection area the position of which is variably set within the image sensing plane. The light measuring area is set in the object's position within the image sensing plane detected by the determining circuit. The exposure control device is provided further with a changing circuit which detects the size of the object on the image sensing plane and changes the size of the light measuring area accordingly, and a weighting circuit which performs for light measurement a weighting operation on video signals obtained from the inside and outside of the light measuring area.
