Claims (9)

An image processing apparatus capable of performing image transformation,
A candidate area setting unit for setting an area including the specific image on the target image as a candidate area for the transformation process;
For the set candidate area, an exclusion determination unit that determines an area to be excluded from the deformation processing target according to a predetermined exclusion condition;
A deformation processing unit that performs deformation of an image in the region for candidate regions other than the candidate region determined to be excluded by the exclusion determination unit;
An image processing apparatus comprising:   The exclusion determination unit acquires the size of the specific image and the inclination on the target image, determines whether or not the acquired size falls within a size upper limit value determined according to the acquired inclination, The image processing apparatus according to claim 1, wherein a candidate area having a specific image whose acquired size exceeds a size upper limit value is excluded from a target for deformation processing.   Whether the acquired size falls within the size upper limit value by referring to the size upper limit value defining information in which the size upper limit value is set to a smaller value as the inclination approaches the predetermined upper limit angle. The image processing apparatus according to claim 2, wherein the determination is performed.   The exclusion determination unit determines whether or not the inclination of the specific image belongs to a predetermined angle range, and excludes candidate areas whose inclination of the specific image is outside the predetermined angle range from the target of the deformation process. The image processing apparatus according to claim 2 or 3.   When there are candidate areas having different vertical orientations of the specific image, the exclusion determination unit corresponds to the direction in which the upper direction of the specific image corresponds to the direction in which the number of candidate areas having the same vertical orientation of the specific image is the largest. The image processing apparatus according to claim 2, wherein candidate regions other than the existing candidate region are excluded from the target of the deformation process.   When there are a plurality of directions in which the number of candidate areas having the same vertical direction is maximized, the upward direction of the specific image is the direction corresponding to the candidate area having the specific image with the largest size among the plurality of directions. 6. The image processing apparatus according to claim 5, wherein candidate areas other than the corresponding candidate areas are excluded from the target of the deformation process.   When there are a plurality of directions in which the number of candidate regions having the same vertical direction is maximized, the upward direction of the specific image corresponds to one direction selected according to a predetermined priority among the plurality of directions. The image processing apparatus according to claim 5, wherein candidate areas other than the candidate areas are excluded from the target of the deformation process.   When the number of candidate areas exceeds a predetermined threshold, the exclusion determination unit selects a number of candidate areas that fall within the threshold according to the size of the specific image, and performs transformation processing on the candidate areas that are not selected. The image processing apparatus according to any one of claims 2 to 7, wherein the image processing apparatus is excluded from the target.   The candidate area setting unit detects a face image on a target image as the specific image, and sets a candidate area for each face image based on the detected face image. The image processing apparatus according to any one of the above.
