Abstract
For each image data, face information indicating the number of faces of subjects included in an image is added. Further, the percentage of images in which there exist faces is calculated. When the percentage exceeds a face detecting flag threshold, the face detecting flag is set ON. When the percentage does not exceed the face detecting flag threshold, the face detecting flag is set OFF. The face detecting flag is stored in the flash memory portion of the memory. The face detecting flag is read from the flash memory portion of the memory in the shooting mode at the next time. When the face detecting flag is set ON, an image display device displays instructions on prompting a user to make the face detecting function effective.
Claims21
An image taking device comprising:
- an image taking device which picks up an object image and converts the image into image data;
- a face detecting device which detects whether there exist one or more human faces in the image data;
- a switching device which switches a face detecting function to its effective or its ineffective position;
- a controlling device, when the face detecting function is switched to its effective position and one or more faces are detected in the image data, which automatically controls at least one of exposure, focus, white balance and picture quality so that the detected faces can be optimally photographed;
- a recording device which records in a recording medium, face information representing the presence of a face in the image data associated with the image data based on detection result by the face detecting device;
- a determining device which determines based on the face information, whether a percentage of image data in which there exist one or more faces in the image data recorded in the recording medium exceeds a predetermined threshold;
- and
- an instructing device which provides an instruction on prompting a user to switch the face detecting function to its effective position when the determining device determines that the percentage of image data in which there exist faces exceeds the predetermined threshold at the time of turning on a power supply.
An image taking device comprising:

- a face detecting device which detects whether there exist one or more human faces in the image data;
- a switching device which switches a face detecting function to its effective or its ineffective position;
- a controlling device, when the face detecting function is switched to its effective position and one or more faces are detected in the image data, which automatically controls at least one of exposure, focus, white balance and picture quality so that the detected faces can be optimally photographed,
- a recording device which records in a recording medium, face information representing the presence of a face in the image data associated with image based on detection result by the face detecting device;
- and
- a determining device which determines based on the face information, whether a percentage of image data in which there exist one or more faces in the image data recorded in the recording medium exceeds a predetermined threshold;
- wherein
- the switching device automatically switches the face detecting function to its effective position when the determining device determines that the percentage of image data in which there exist one or more faces exceeds the predetermined threshold at the time of turning on the power supply.
A control method for image taking in a image taking device comprising a switching device which manually switches a face detecting function to its effective or ineffective position, wherein the face detecting function is made ineffective at the time of turning a power supply on, and when the face detecting function is switched to its effective position after the power supply has been set ON and one or more faces are detected in image data to be photographed, to automatically control at least one of exposure, focus, white balance and picture quality so that the detected faces can be optimally photographed, the control method for image taking comprising the steps of:
- detecting whether there exist one or more faces in all image data recorded in a recording medium or in the image data within a predetermined period of time from a latest image data or in a predetermined number of image data selected from the latest image data;
- determining a percentage of image data in which there exist one or more faces in all image data detected as to whether there exist the faces;
- and
- providing an instruction on prompting a user to switch the face detecting function to its effective position when a percentage of image data in which there exist one or more faces exceeds a predetermined threshold at the time of turning on the power supply.
A control method for image taking, when a face detecting function is switched to its effective position and one or more faces are detected in image data to be photographed, automatically controlling at least one of exposure, focus, white balance and picture quality so that the detected faces can be optimally photographed, the control method for image taking comprising the steps of:
- detecting whether there exist one or more faces in all image data recorded in a recording medium or in image data within a predetermined period of time from a latest image data or in the predetermined number of image data selected in reverse chronologic order from the latest image data;
- determining the percentage of image data in which there exist one or more faces to all image data detected as to whether there exist the faces;
- and
- making the face detecting function effective when the percentage of image data in which there exist one or more faces exceeds a predetermined threshold at the time of turning on a power supply.
