Image sensing system comprising a image sensing unit and a computer

摘要

In an image sensing apparatus using an image sensing device, such as a CCD (102), to be used by connecting to an external device, such as a computer (12), an operating rate of the CCD is changed in accordance with a rate at which the computer receives image signals from the image sensing apparatus. Further, when the operating rate of the CCD is changed, a proper exposure value is conjectured to obtain an image sensed at a proper exposure on the basis of operating rates of the CCD before and after the operating rate is changed, and a proper exposure value of the CCD before the operating rate is changed.
