Image processing apparatus, image processing method, image processing system, and non-transitory computer readable medium

An image processing apparatus comprising:

• a memory storing a program;
• and
• a processor that, when instructed by the stored program, performs the functions of:
• a position information obtaining unit that obtains position information indicating a representative position of one or more designated regions in an image;
• a first region detection unit that detects the one or more designated regions from the position information;
• a designated region enlargement unit that enlarges the detected designated regions;
• and
• a second region detection unit that detects the one or more designated regions again within a boundary portion of the enlarged designated regions, based on a reference pixel selected from among pixels belonging to a region in the image other than the boundary portion,
• the first region detection unit detecting two designated regions, and
• the setting cancellation within the predetermined portion of the image being performed by applying a filter for canceling a setting of the pixels within the predetermined portion of the image, the predetermined portion of the image being a boundary of the two designated regions.

An image processing system comprising:

• an additive-color-mixing display that displays an image;
• a processor that performs image processing on image information on the image displayed on the display device;
• and
• a touch-sensitive input device that inputs an instruction from a user to the image processing apparatus to perform image processing,
• the processor performing the functions of
• a position information obtaining unit that obtains position information indicating a representative position of one or more designated regions in the image, and
• a region detection unit that detects the one or more designated regions from the position information,
• wherein the region detection unit cancels a setting of the one or more designated regions for pixels within a predetermined portion of the image, and detects the one or more designated regions again for the pixels within the predetermined portion, based on a reference pixel selected from among pixels on the image for which the setting of the one or more designated regions has not been canceled,
• the region detection unit detecting two designated regions, and
• the setting cancellation within the predetermined portion of the image being performed by applying a filter for canceling a setting of the pixels within the predetermined portion of the image, the predetermined portion of the image being a boundary of the two designated regions.

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

• obtaining position information indicating a representative position of one or more designated regions in an image;
• and
• detecting the one or more designated regions from the position information,
• wherein the detecting includes canceling a setting of the one or more designated regions for pixels within a predetermined portion of the image, and detecting the one or more designated regions again for the pixels within the predetermined portion, based on a reference pixel selected from among pixels on the image for which the setting of the one or more designated regions has not been canceled,
• the region detection step detecting two designated regions, and
• the setting cancellation within the predetermined portion of the image being performed by applying a filter for canceling a setting of the pixels within the predetermined portion of the image, the predetermined portion of the image being a boundary of the two designated regions.
