Abstract:
1. A processing apparatus adapted to be used in a video system that includes a main lens onto which light from an object is made incident, a splitting unit operable to split the light transmitted by the main lens, and relay lenses onto which light of video images split by the splitting unit is made incident, the processing apparatus comprising: a gamma removal unit structured and arranged to remove gamma processing according to a gamma value, the gamma processing performed on video data to which video data of optically overlapped video images are imparted, the optically overlapped video images being generated by setting the splitting unit at a position other than a position where the focal position of the main lens and the focal position of the relay lenses coincide with each other; an addition unit synthesizing adjacent video data in the video data from which the gamma processing is removed; a gamma addition unit re-performing gamma processing on the synthesized video data; and a gamma adjustment unit adjusting the gamma value used to remove the gamma processing in the gamma removal unit, by changing gamma values used for each data of the optically overlapped video images in a direction that reduces non-flatness of brightness along a line that traverses across overlapped portions of the video data of optically overlapped video images.
