Abstract:
1. A video signal processing apparatus, comprising: an image pickup unit having a focus lens; an evaluation value calculator unit, which is configured to specify a region, in which brightness higher than a predetermined value lies, from within a region to be a target, for which a focal point estimation value is calculated to be used for moving said focus lens to a focal point, and to calculate the focal point estimation value by excluding the region, in which said brightness higher than the predetermined value lies, from a focal point estimation value calculation target; and a system controller unit, which is configured to control to be focused upon basis of the focal point estimation value calculated by said evaluation value calculator unit, wherein said system controller unit controls said focus lens to move to a predetermined position, when a ratio of the region, in which said brightness higher than the predetermined value lies, to the region be the target, for which the focal point estimation value is calculated, is greater than a threshold value, and completes the processes of the auto focus (AF) control without calculating a focal point estimation value of said predetermined position by said evaluation value calculator unit.
