Problems solved by technology

[0005] However, in the above invention, no correction is performed to make an image in which the impression given by the image features of the area of ​​interest is stronger than that given by the image features of the non-attention area
Therefore, when image features are compared between the area of ​​interest and the area of ​​non-interest, there is a problem that it is not always possible to create an image in which the main subject stands out.

Embodiment Construction

[0053] The first embodiment of the present invention will be described.

[0054] use figure 1 The imaging device of this embodiment will be described. figure 1 It is a schematic block diagram showing a part of the imaging device of this embodiment. The imaging device described below functions as an image processing device that processes captured images.

[0055] The imaging device of this embodiment includes an imaging element (image acquisition unit) 1 , an image analysis unit 2 , an image processing unit (image characteristic adjustment unit) 3 , a display unit 4 , a recording unit 5 , and an imaging control unit 6 .

[0056] The imaging element 1 outputs an electrical signal corresponding to light incident on the light receiving surface at a predetermined timing. The imaging element 1 is, for example, a type called a CCD (Charge Coupled Device) or a CMOS (Complementary Metal Oxide Semiconductor) sensor, or other various types of imaging elements.

Abstract

The present invention provides an image processing device and an image processing method. The image processing device that corrects an obtained image includes: an image acquisition unit that obtains the image; a region setting unit that sets a first region including a main object and a second region not including the main object on the image; an image characteristic amount calculation unit that calculates a first image characteristic amount, which is an occurrence state of a predetermined image characteristic amount, respectively in the first region and the second region; a comparison unit that compares the first image characteristic amounts of the first region and the second region; and an image characteristic adjustment unit that adjusts a second image characteristic amount of the obtained image on the basis of a comparison result obtained by the comparison unit.

Description

technical field [0001] The present invention relates to an image processing device and an image processing method. Background technique [0002] Conventionally, there is a method of correcting chromaticity as a method of correcting a captured image. A method of correcting chromaticity is disclosed, for example, in JP2000-224607A. [0003] In JP2000-224607A, an image is divided into a plurality of regions, and a chromaticity level is calculated for each region. Then, based on the area with the highest chroma level, the chroma correction of the whole image is performed. [0004] Generally speaking, it is preferable that the attention area including the main subject in the image obtained by shooting is more conspicuous. That is, it is desirable to obtain an image in which the impression brought by the image features of the attention area is stronger than the impression brought by the image features of the non-interest area when comparing the attention area with the non-inter...
