To provide a synthetic image luminance correction apparatus configured to generate a synthetic image with low congruity.SOLUTION: A boundary average value calculation unit 41 calculates an average value of luminance in each of a first number of boundary areas that face each other across boundaries of a front image, a rear image, a left side image, and a left side image. The boundary average value calculation unit 41 compares a threshold with an absolute value of a difference between each pair of the boundary areas facing across the boundaries. The boundary average value calculation unit 41 calculates boundary average values in different ways in accordance with whether the number of pairs of the first number of boundary areas for which the absolute value of the difference is less than the threshold is equal to or larger than a second number or less than the second number. A correction amount calculation unit 42 calculates a boundary correction amount for correcting luminance of at least one boundary area between the left side image and the right side image, and the front image and the rear image. An adder 43 adds the boundary correction amount to image data.SELECTED DRAWING: Figure 3

    【課題】違和感の少ない合成画像とすることができる合成画像輝度補正装置を提供する。【解決手段】境界平均値算出部41は、前方画像、後方画像、左側方画像、左側方画像の各境界を挟んで互いに対向する第1の数の境界領域の各境界領域における輝度の平均値を算出する。境界平均値算出部41は、境界を挟んで互いに対向する各対の境界領域の差分の絶対値と閾値とを比較する。境界平均値算出部41は、第1の数の対の境界領域のうち、差分の絶対値が閾値未満である対の数が第2の数以上であるか第2の数に満たないかによって、境界平均値の算出の仕方を異ならせる。補正量算出部42は、左側方画像及び右側方画像と前方画像及び後方画像との少なくとも一方の境界領域の輝度を補正するための境界補正量を算出する。加算器43は、画像データに境界補正量を加算する。【選択図】図3
