Photography control method and apparatus for prohibiting use of flash
View Patent ↗A photography control method, apparatus, and computer readable medium for prohibiting the use of a flash. The method includes recognizing a sensitive face from an obtained image and prohibiting the use of the flash when the recognized face is a sensitive face. The method may include determining whether or not the image is taken from a dark environment and if the image is taken from a dark environment, then increasing the optical sensitivity and optionally performing advanced shake reduction.
1. A photography control method for controlling use of a flash, the method comprising:
determining, using a processor, whether an image contains a sensitive face; and
when the image contains the sensitive face:
prohibiting the use of the flash;
increasing an optical sensitivity for photographing while the flash is prohibited;
capturing at least two images including the sensitive face while the flash is prohibited and the optical sensitivity is increased; and
combining the at least two images to form a composite image to compensate for the increased optical sensitivity and the prohibiting the use of the flash.
2. The photography control method of claim 1 , wherein determining whether the image contains the sensitive face comprises:
recognizing a face in the image; and
determining that the image contains the sensitive face when the recognized face is determined to be a face of a baby.
3. The photography control method of claim 1 , further comprising performing shake reduction while the at least two images are captured.
4. The photography control method of claim 1 , wherein, in the capturing, the at least two images are obtained with different settings for obtaining the at least two images.
5. A computer program product comprising a non-transitory computer-readable medium storing:
a first set of codes for causing a computer to determine whether an image contains a sensitive face; and
a second set of codes for causing the computer to, when the image contains the sensitive face, at least:
prohibit the use of a flash;
increase an optical sensitivity for photographing while the flash is prohibited;
capture at least two images of the sensitive face while the flash is prohibited and the optical sensitivity is increased; and
combine the at least two images to form a composite image to compensate for the increased optical sensitivity and the prohibiting the use of the flash.
6. A photography control apparatus for prohibiting the use of a flash, the apparatus comprising:
a face recognition unit configured to recognize a face from an obtained image; and
a control unit configured to, when the recognized face is a sensitive face:
prohibit the use of the flash;
increase an optical sensitivity for photographing while the flash is prohibited;
capture at least two images of the recognized face while the flash is prohibited and the optical sensitivity is increased; and
combine the at least two images to form a composite image to compensate for the increased optical sensitivity and the prohibiting the use of the flash.
7. A photography control method for controlling use of a flash, the method comprising:
determining, using a processor, whether an image contains a sensitive face; and
when the image contains the sensitive face:
prohibiting the use of the flash;
increasing an optical sensitivity for photographing while the flash is prohibited;
capturing at least two images including the sensitive face while the flash is prohibited and the optical sensitivity is increased; and
combining the at least two images to form a composite image to compensate for the increased optical sensitivity and the prohibiting the use of the flash,
wherein, in the capturing, one image of the at least two images is obtained with settings as for low gain and long exposure and another image of the at least two images is obtained with setting for reduced exposure time and high gain.
