Abstract
According to the present invention, by providing operation members dedicated for an operation of switching on/of the face detection processing, a face image switching operation, and proceeding to the next image taking, operations related to the face detection processing can be simplified. Furthermore, by displaying a taken image and an face image at the same time, the operation of proceeding to the next image taking after confirming the condition of focus and exposure and the face expression of a subject person can be performed easily.
Claims36
An image-taking apparatus comprising:
- an image-taking device which takes an image of a subject;
- a display device which displays the image taken by the image-taking device;
- a face detection device which detects a face of a person who is the subject, from the taken image;
- a face detection control button for inputting an instruction to set on/off of face detection processing performed by the face detection device;
- and
- a display control device which controls the face detection device to execute the face detection processing for an image taken when the face detection processing is set to on, and causes the display device to display a face image including a face area detected from the taken image, wherein,
- when a number of horizontal pixels of an area including the face image and to be cut out from the taken image to be displayed on a face display screen of the display device are less than a number of horizontal pixels of the face display screen, or when a number of vertical pixels of the area to be cut out are less than a number of vertical pixels of the face display screen, the face detection device enlarges a height and/or width of the area to be cut out so that the number of vertical pixels and the number of horizontal pixels of the area to be cut out are equal to or greater than the number of vertical pixels and the number of horizontal pixels of the face display screen, respectively.
