Problems solved by technology

[0004] However, even if the processing intensity is controlled according to the size of the person's face as described above, the person's face and other parts cannot be blurred with an appropriate processing intensity
The same is true for subjects other than people and image processing other than soft focus. There is a problem that the processing intensity of image processing for the main subject and other parts cannot be appropriately controlled.

Embodiment approach 1

[0021] First, a first embodiment of the present invention will be described. figure 1 It is a block diagram showing an electrical configuration of a digital camera 1 as one form of an image processing device according to the present embodiment and a second embodiment described later.

[0022] Such as figure 1 As shown, the digital camera 1 includes a control unit 2 , a lens unit 3 , an imaging unit 4 , a display unit 5 , an image storage unit 6 , a program storage unit 7 , a face detection unit 8 , an operation unit 9 , and a power supply unit 10 .

[0023] The control unit 2 includes CPU (Central Processing Unit, central processing unit) and its peripheral circuits, RAM (Random Access memory, random access memory) and other working internal memories, image processing circuits, controls each part of the digital camera 1, and also performs subsequent operations. Various image processing described above.

[0024] The lens unit 3 is composed of a lens group including a focus ad...

Embodiment approach 2

[0082] Next, a second embodiment of the present invention will be described. Unlike the first embodiment, at the time of shooting, the subject brought into focus by AF control is set as the main subject, that is, the subject to be paid attention to. That is, the present embodiment is as follows: figure 1 In the digital camera 1 having the configuration shown above, in addition to the various data described above, the following data and programs are stored in the program storage unit 7 .

[0083] That is, in the present embodiment, a distance acquisition table (table) indicating the relationship between the adjustment position of the lens group in the lens unit 3 and the focus distance (the distance to the subject having focus) is stored in the program storage unit 7. ). In addition, the program storage unit 7 stores an AF control program for the so-called continuous AF that causes the control unit 2 to continuously focus on a subject that is relatively moving in the image, a...

Abstract

The invention provides an image processing apparatus and an image processing method, which properly controls the processing strength of an image of a main photographic subject which is imaged during the image processing. The position and the size of a target photographic subject such as the face of a person in an original image (G1) acquired by image capturing is acquired, and then mask information (M3) indicating a relation between a position to be subjected to predetermined image processing in the original image (G1) and the strength of the predetermined image processing is generated based on the acquired position and size. Subsequently, a new image (G3) is generated by predetermined image processing of a different strength being performed on each position in the original image (G1) by use of the generated mask information (M3). In the generation of the new image (G3), for example, one of the original image (G1) and a processed image (G2) acquired by the predetermined image processing being performed on the original image (G3) is combined with the other image by use of transmissivity indicated by the mask information (M3) for each pixel.

Description

[0001] This application claims priority based on Japanese Patent Application Japanese Patent Application No. 2015-010793 for which it applied on January 23, 2015, and uses the whole content of this basic application for this application. technical field [0002] The present invention relates to an image processing device and an image processing method. Background technique [0003] Conventionally, as a kind of image processing performed in digital cameras and the like, there is known soft focus processing in which blurring similar to that caused by chromatic aberration, spherical aberration, etc. Brew a soft atmosphere. As a technology related to the soft-focus processing, for example, Japanese Patent Application Laid-Open No. 2000-69277 discloses the following technology: In order to avoid stereotyped changes irrespective of the content of the original image, the face of a person is detected from the original image, and based on Its size controls the processing intensity. ...
