An image processing apparatus according to the present invention including a first acquisition unit configured to acquire color information of a first object obtained by capturing an image of the first object illuminated with light emitted by a light source, a second acquisition unit configured to acquire color information of a second object based on a condition determined by a direction of capturing the image of the first object, a direction of illuminating the first object with light from the light source, and a direction of a normal of the first object, and an output unit configured to output information according to the color information of the first object and the color information of the second object.

Image processing apparatus, method and storage medium, for object color evaluation

An image processing apparatus includes first and second acquisition units, a determination unit, and an estimation unit. The first acquisition unit is configured to acquire shape information of an object. The second acquisition unit is configured to acquire a plurality of pieces of image data. The determination unit is configured to determine a pixel position corresponding to a position at which an orientation of a surface is the same as or similar to an orientation of a surface at a position of interest on the object, as a pixel position for estimating a reflection characteristic of the object at the position of interest. The estimation unit is configured to estimate the reflection characteristic of the object at the position of interest by using a pixel value at the pixel position determined by the determination unit.

Image processing apparatus, image processing method, and storage medium to estimate reflection characteristic of object

An image processing apparatus includes an acquisition unit and a generation unit to generate image data representing an image containing luminous points caused by light reflection on a plurality of flakes contained in a coating material in a case of coating an object with the coating material. The acquisition unit acquires information about the coating material. The generation unit generates the image data representing the image containing the luminous points based on the information about the coating material.
