Image processing apparatus, image processing method, and non-transitory computer readable medium comprising extracting first target image and second target image from a reading target and forming a composite image comprised of a non-glossy region and a glossy region after performing an alignment of target images

An image processing method comprising:

• extracting a first target image corresponding to a reading target having a glossy portion and a non-glossy portion from a first read image acquired by optically reading the reading target in a first reading environment, and extracting a second target image corresponding to the reading target from a second read image acquired by optically reading the reading target in a second reading environment in which specular light acquired from the reading target by an image sensor is of higher intensity compared to the first reading environment;
• executing an alignment of the first target image and the second target image if positions of the first and second target images do not coincide with each other and if the first and second target images are alignable by translating or rotating at least one of the first target image or the second target image;
• forming a composite image by executing a composition process that composites a non-glossy region corresponding to the non-glossy portion extracted from the first target image with a glossy region corresponding to the glossy portion extracted from the second target image;
• notifying a user that the alignment is available if the alignment is available;
• and
• notifying the user that the alignment is unavailable if the alignment is unavailable.

A non-transitory computer readable medium storing a program causing a computer to execute a process for image processing, the process comprising:

• extracting a first target image corresponding to a reading target having a glossy portion and a non-glossy portion from a first read image acquired by optically reading the reading target in a first reading environment, and extracting a second target image corresponding to the reading target from a second read image acquired by optically reading the reading target in a second reading environment in which specular light acquired from the reading target by an image sensor is of higher intensity compared to the first reading environment;
• executing an alignment of the first target image and the second target image if positions of the first and second target images do not coincide with each other and if the first and second target images are alignable by translating or rotating at least one of the first target image or the second target image;
• forming a composite image by executing a composition process that composites a non-glossy region corresponding to the non-glossy portion extracted from the first target image with a glossy region corresponding to the glossy portion extracted from the second target image;
• notifying a user that the alignment is available if the alignment is available;
• and
• notifying the user that the alignment is unavailable if the alignment is unavailable.
