Benefits of technology

This patent text describes a way to easily set the skin color of an object. It provides a technique that helps in accurately and easily identifying the specific area of skin color on an object.

Problems solved by technology

Therefore, it is difficult to determine how the “hue”, “color density”, and “range of color region” of the skin color region setting menu need to be adjusted in order to correctly set a skin color region for the skin color of an object.

Embodiment Construction

[0020]An embodiment of the present invention will be described below with reference to the accompanying drawings.

[0021]FIG. 1 is a block diagram showing an example of the arrangement of an image capturing apparatus 100 according to the embodiment of the present invention. Referring to FIG. 1, an optical system 101 is formed from a zoom lens group, a stop, an ND filter, and the like. An image capturing unit 102 is formed from a CCD serving as an image sensor, a sample and hold circuit (S / H circuit), a preprocess circuit, and the like. A signal processing unit 103 includes an image quality adjustment unit 104, and performs predetermined image processing for a video signal provided by the image capturing unit 102. The image processing includes skin detail processing (to be described later), and processing of superimposing a zebra pattern on a skin color region to undergo the skin detail processing. A signal recording unit 105 performs encoding / decoding processing for an input video sig...

Abstract

An image capturing apparatus for capturing an object and generate an image, displaying the image, performing signal processing for the image, and accepting an input from a user, wherein the image is displayed with a vectorscope superimposed thereon, the vectorscope indicating a distribution of color components included in the image based on a hue and a color density and an index for specifying a range of a skin color region in the image, a display position of the index on the vectorscope is specified based on the hue and the color density values, and a size of the index is specified by the range of the skin color region value, and processing is performed for decreasing a detail level of an image signal of the image having a color component included in the index.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an image capturing apparatus, a control method therefor, and a computer program.[0003]2. Description of the Related Art[0004]In recent years, digital video cameras using randomly accessible recording media such as an optical disk, hard disk drive, and flash memory, in addition to a conventionally known magnetic tape have become widespread as apparatuses for recording videos. Some manufacturers compete against each other in terms of advanced functions and higher performance of such widespread video cameras.[0005]To satisfy user's need to beautifully shoot an object, for example, a function of setting details of image quality adjustment of a video camera body, and a skin detail function as part of the setting function are provided. The skin detail function aims, when shooting the person, to select and set the skin color region of a person, and beautifully represent the skin of the person b...
