If the two agree, then a display is presented based upon processed image data within the image file. If the two do not agree, then unprocessed image data within the same file is subjected to image processing in accordance with the set parameter and the processed image is displayed.

Abstract: An image capturing device having a function of clamping an image signal. When the image capturing device is activated, a synchronous signal generating section begins creation of a horizontal synchronous signal, and a counter begins counting a pulse of the horizontal synchronous signal. When the counted value reaches a predetermined value, the clamping capability control section changes the level of a clamp mode signal to an H level. During a period from the start of power supply to the image capturing device to the raising of the level of a clamp mode signal to an H level, a clamp pulse generating section sets a longer width for a clamp pulse than in a normal operation so that a switch element of a clamping circuit remains in an on state in a longer period, whereby a smaller time constant for clamping is set. After elapse of a predetermined period, the switch element is controlled so as to remain in an ON state in a normal period, which is relatively short, whereby a larger time constant for clamping is set.
