Embodiment Construction

[0042] figure 1 A preferred embodiment of the eye color correction device is shown. In terms of hardware, the eye color correction device 10 includes: a CPU (Central Processing Unit), a main storage device (RAM), an auxiliary storage device, etc. connected via a bus. The auxiliary storage device is configured using a nonvolatile storage device. The nonvolatile storage device referred to here refers to so-called ROM (including EPROM, EEPROM, mask ROM, etc.), FRAM, hard disk, and the like. The eye color correction device 10 may be configured by installing a predetermined application program on a personal computer, or may be configured as a dedicated device.

[0043] Such as figure 1 As shown, the eye color correction device 10 of this embodiment is loaded into the main storage device by various programs (OS, application, etc.) stored in the auxiliary storage device and executed by the CPU, thereby serving as an 12. The skin color determination unit 13, skin corrected color c...

Abstract

It is an object to provide a pupil color correction device that can correct a person's pupil color in the case where possible abnormalities occurring at images of pupil portions, such as red-eye phenomena, take place from a photographed person's image and an original pupil color of the person is deemed not to be completely lost by the phenomena. A pupil color correction device is provided with a skin color specifying unit (13) for specifying a skin color of an object person in an input image, a skin correcting color calculating unit (14) for seeking a skin correcting color that is a person's pupil color estimated in accordance with the specified skin color, an original pupil color calculating unit (16)for seeking an original pupil color that is a representative pupil color of a surrounding region of the person's pupil from pixel colors included in the surrounding region, a correction standard color determining unit (17) for acquiring the sought skin correcting color and original pupil color to determine either of them to be a pupil correcting standard color, and a correcting unit (19) for correcting the object person's pupil color in accordance with the correcting standard color.

Description

technical field [0001] The present invention relates to an eye color correction device and a program, and relates to an effective technology applicable to an imaging device that captures an image (particularly, an image of a person's face), an information processing device, an output device, software, etc. that process an image. Background technique [0002] Regardless of the digital camera or the silver halide camera, when shooting with a flash, there is a problem of a red-eye phenomenon in which the pupil of the eye or the entire eye turns red. As a similar problem, there is also a yellow eye phenomenon in which the pupils of a person and the entire eyes are photographed yellow. Such a red-eye / yellow-eye phenomenon (hereinafter, the red-eye phenomenon will be described as an example) is a phenomenon caused by retinal reflection of a light incident from the pupil portion of the eye into the eyeball. As the miniaturization of cameras has progressed and the distance between ...
