Abstract
An image processing apparatus generates a normal image, when lighting correction of an image is performed using three-dimensional shape data. Three-dimensional shape data of a predetermined object is adjusted with a subject in position, based on a feature pattern detected in image data, and lighting processing for correcting a pixel value of the image data is performed based on the adjusted three-dimensional shape data, distance information of the subject, and a position of a virtual light source. When the three-dimensional shape data is adjusted with the image data in position, a region having a large irregularity in the three-dimensional shape data is preferentially adjusted in position.
Claims10
An image processing apparatus comprising:
- an acquisition unit configured to acquire a captured image obtained by capturing an object;
- a specifying unit configured to specify a region including in at least part of the object in the captured image;
- and
- a generation unit configured to generate a correction image in which brightness of at least part of the specified region in the captured image is changed using pixel values of pixels in the captured image,
- wherein a degree of change from brightness of the specified region in the captured image to brightness of the specified region in the correction image corresponds to the brightness of the specified region in the captured image.
An image processing method for generating a correction image in which brightness of a captured image acquired by capturing an object is changed, the image processing method comprising:
- acquiring the captured image;
- specifying a region including in at least part of the object in the captured image;
- and
- generating the correction image in which brightness of at least part of the specified region in the captured image is changed using pixel values of pixels in the captured image,
- wherein a degree of change from brightness of the specified region in the captured image to brightness of the specified region in the correction image corresponds to the brightness of the specified region in the captured image.
A non-transitory computer-readable storage medium storing instructions that, when executed by a computer, cause the computer to perform a method for generating a correction image in which brightness of a captured image acquired by capturing an object is changed, the image processing method comprising:
- acquiring the captured image;
- specifying a region including in at least part of the object in the captured image;
- and
- generating the correction image in which brightness of at least part of the specified region in the captured image is changed using pixel values of pixels in the captured image,
- wherein a degree of change from brightness of the specified region in the captured image to brightness of the specified region in the correction image corresponds to the brightness of the specified region in the captured image.
