An image processing apparatus comprising: a fusion processing section configured to produce a fusion image obtained by fusion of a monochrome imaged image obtained by imaging a subject and a color imaged image by imaging the subject from a different point-of-view position; and a fusion decision processing section configured to decide whether or not the fusion image produced in the fusion processing section fulfills a predetermined condition, wherein the fusion decision processing section is configured to determine that the fusion image is outputted in a case where it is decided that the predetermined condition is fulfilled, and determines that an image other than the fusion image is outputted in a case where it is decided that the predetermined condition is not fulfilled; the fusion decision processing section is configured to decide whether or not the fusion image fulfills the predetermined condition based on a feature amount with respect to the monochrome imaged image and the color imaged image; the fusion decision processing section is configured to determine that the fusion image is outputted in a case where it is decided that deterioration is not caused in the fusion image based on the feature amount with respect to the monochrome imaged image and the color imaged image, and is configured to output an image other than the fusion image in a case where it is decided that the deterioration is caused in the fusion image; the fusion decision processing section is configured to use camera information with respect to an imaging section acquiring the monochrome imaged image, and an imaging section acquiring the color imaged image as the feature amount; and the fusion decision processing section is configured to use imaging setting information associated with the monochrome imaged image and the color imaged image as the camera information. a fusion processing section configured to produce a fusion image obtained by fusion of a monochrome imaged image obtained by imaging a subject and a color imaged image by imaging the subject from a different point-of-view position; and a fusion decision processing section configured to decide whether or not the fusion image produced in the fusion processing section fulfills a predetermined condition, wherein the fusion decision processing section is configured to determine that the fusion image is outputted in a case where it is decided that the predetermined condition is fulfilled, and determines that an image other than the fusion image is outputted in a case where it is decided that the predetermined condition is not fulfilled; the fusion decision processing section is configured to decide whether or not the fusion image fulfills the predetermined condition based on a feature amount with respect to the monochrome imaged image and the color imaged image; the fusion decision processing section is configured to determine that the fusion image is outputted in a case where it is decided that deterioration is not caused in the fusion image based on the feature amount with respect to the monochrome imaged image and the color imaged image, and is configured to output an image other than the fusion image in a case where it is decided that the deterioration is caused in the fusion image; the fusion decision processing section is configured to use camera information with respect to an imaging section acquiring the monochrome imaged image, and an imaging section acquiring the color imaged image as the feature amount; and the fusion decision processing section is configured to use imaging setting information associated with the monochrome imaged image and the color imaged image as the camera information.
