Image processing apparatus, image processing method, image processing program, and recording medium storing program

An image processing method comprising:

• reading, from a storage device in which a plurality of images captured at the same event are stored, the plurality of images, by a reading device;
• calculating a ratio of a number of users who imaged a specific subject among the plurality of images read by the reading device to a number of users who imaged the plurality of images read by the reading device, by a processor;
• deciding a user who imaged the specific subject to be a first user based upon the calculated ratio, by the processor;
• and
• detecting a first attribute obtained from a first image group captured at the same event by the first user, which is different from a second attribute obtained from a second image group captured at the same event by second users of which a number is larger than a number of the first user, by an attribute detecting device,
• wherein the user is set as the first user in a case where the calculated ratio is less than a threshold value, and
• the first attribute is set as a feature of the first user.

A non-transitory recording medium storing a computer-readable program for controlling a computer of an image processing apparatus, the program controlling the computer to execute:

• reading a plurality of images from a storage device in which the plurality of images captured at the same event are stored;
• calculating a ratio of a number of users who imaged a specific subject among the plurality of images read to a number of users who imaged the plurality of images read;
• deciding a user who imaged the specific subject to be a first user based upon the calculated ratio;
• and
• detecting a first attribute obtained from a first image group captured at the same event by the first user, which is different from a second attribute obtained from a second image group captured at the same event by second users of which a number is larger than a number of the first user,
• wherein the user is set as the first user in a case where the calculated ratio is less than a threshold value, and
• the first attribute is set as a feature of the first user.
