In the video processing device, a correction amount update determining
unit determines whether to update a correction amount based on an input
image obtained from an image input unit and when a cut point is detected
or when the number of frames in a number of frames storing unit exceeds a
fixed value, determines that update is required, and at this time, a
correction amount obtaining unit obtains a new correction amount based on
the input image. Then, if no cut point is detected, an amount of change
of a correction amount in time is limited and the obtained result is
recorded in a correction amount storing unit, and an image correcting
unit conducts quality improving correction processing with respect to the
input image based on a correction amount recorded in the correction
amount storing unit and the image corrected is sent to an image output
unit.
