no. 1 approach

[0022] figure 1 It is a diagram showing the circuit configuration of the digital camera 1 functioning as the image processing device according to the first embodiment of the present invention.

[0023] The digital camera 1 of this embodiment has, as basic operation modes, a recording mode for capturing still images or moving images, and a playback mode for reproducing captured images. In addition, the photography mode includes a normal mode, a scene mode, a video mode, and the like. Among them, as the lower modes of the scene mode, a portrait shooting mode, a landscape shooting mode, a liquid crystal shooting mode, and the like are set. The portrait photography mode is a photography mode suitable for photographing people.

[0024] Such as figure 1 As shown, a digital camera 1 includes: a photographing lens 2, an imaging unit 3, a pre-processing unit 4, a processing information storage unit 5, a program memory 6, an image processing unit 7, a control unit 8, an image recordi...

no. 2 approach

[0064] In the second embodiment, the second processing of becoming a subject is performed.

[0065] also, figure 1 The digital camera 1 also functions as the image processing device according to the second embodiment. Therefore, the description of its circuit configuration is the same as that of the first embodiment, and will be omitted here. Among them, the processing information storage unit 5 of the second embodiment does not include the white component gain table storage unit 5a and the reflected light component gain table storage unit 5b, but stores Figure 7 Various information used in the glare suppression processing.

[0066] Next, refer to Figure 7 The shown flowchart describes the procedure of the anti-reflection processing executed by the digital camera 1 of the second embodiment.

[0067] pass figure 1 The shown control unit 8 controls each component to execute the following processing. In addition, when the user operates the shooting mode setting key 11b to...

no. 3 approach

[0117] In the light reflection suppression processing according to the third embodiment, the "first processing" adopted in the first embodiment (refer to Figure 4 Steps S5 to S10), and the "second processing" adopted in the second embodiment (refer to Figure 7 Steps S26 to S31).

[0118] also, figure 1 The digital camera 1 described above functions as the image processing device according to the third embodiment. Therefore, the description of the circuit configuration is the same as that of the first embodiment, so the description is omitted here.

[0119] Therefore, the following reference Figure 10 The shown flowchart describes the procedure of the anti-reflection processing executed by the digital camera 1 of the third embodiment.

[0120] pass figure 1The illustrated control unit 8 executes each component to perform the following processing. Note that the processing in this flowchart is started after the user operates the shooting mode setting key 11b to set any s...

Abstract

An image processing apparatus, including: an image obtaining means that obtains an image; a color area detecting means that detects a predetermined color area from the image thus obtained by the image obtaining means; an area specifying means that specifies an area to be adjusted based on saturation and brightness of the color area thus detected by the color area detecting means; and a color adjusting means that adjusts at least one of a hue, the saturation and the brightness of a pixel in the process area thus specified by the area specifying means.

Description

technical field [0001] The present invention relates to an image processing device and an image processing method. Background technique [0002] For example, Patent Document 1 (Japanese Unexamined Patent Application Publication No. 2006-121416) discloses a technique of performing whitening processing to brighten a highlight (processed) portion of a face region of a digital image of a person. [0003] In the image processing method described in Patent Document 1, a blurred image is generated from an original image to be processed, and whitening processing for brightening a highlighted portion is performed using the blurred image. [0004] In the case of shooting people, depending on the amount of oil on the surface of the face, etc., the indoor lighting or flash light during shooting will write on the face of the person, and the captured image will have an unnatural gloss. This unnatural gloss is called "gloss". In the image processing method described in Patent Document 1,...
