[0039] FIG. 1 is a block diagram illustrating an example of an internal configuration of a new digital camera 1 according to a first embodiment of the present invention.

[0040] In the drawing, a CPU 11 controls each circuit in the digital camera 1 as a whole based on inputs from various operation switches and executes processing according to a camera control program.

[0041] The CPU 11 controls each circuit through the bus 12 . The CPU 11 sends and receives required data to and from the memory 13 . The inside of the memory 13 is divided into ROM, RAM, and flash memory areas. The ROM area stores a camera control program, a start image at startup, an end image at stop, a GUI image such as a menu image for the operation of the digital camera 1, an image for a screen saver, an image showing progress of processing such as a scale changing hourglass image), key operation sounds such as a shutter sound, and sound data representing alarm sounds and error sounds.

[0076] The digital camera 1 according to the second embodiment of the present invention calculates the percentage of images in which faces are detected among the images recorded in the recording medium 31, and automatically enables the face detection function when the number of images in which faces are detected is large .

[0077] FIG. 10 is a flowchart illustrating the operation of the digital camera 1 in the shooting mode.

[0078] When the power of the digital camera 1 is set to ON (step S1001), the CPU 11 disables the face detection function, and then checks to see whether the face detection flag stored in the flash memory portion of the memory 13 is set to ON or OFF (step S1002) .

[0079] When the face detection flag is set to OFF, the camera 1 shifts to a shooting standby state and disables the face detection function (step S1003). After that, shooting is performed by pressing the release button 15 (step S1004). The captured image data is recorded on the recording m...

[0085] FIG. 11 is a flowchart illustrating the operation of the digital camera 1 of the third embodiment in playback mode. Portions common to the flowchart shown in FIG. 6 are given the same reference characters and numerals, and descriptions thereof are omitted.

[0086] The operation of the digital camera 1 in the playback mode of the third embodiment is different from that of the first embodiment in that whether the face detection flag is set to ON or OFF in the images in the recording medium 31 captured within the latest predetermined period is made. judgment.

[0087] As in the case of the first embodiment, when the power is set to ON (step S61), it is detected whether face information is added to the image data of each image that has been photographed and recorded in the recording medium 31 within the past year (step S61). Step S62). Incidentally, the date and time of image shooting are read from the tag information of the image file. For each image to which no face i...

Abstract

The invention discloses image capturing equipment and a control method used for image capturing. For each image data, facial information of the number of the faces of a captured object included in an indicatory image is added, then percentage of the images with faces therein is calculated; when the percentage exceeds a face detecting mark threshold value, the face detecting mark is set as ON; when the percentage does not exceed the face detecting mark threshold value, the face detecting mark is set as OFF; the face detecting mark is stored in the flash memory part of a memory; when in shooting mode next time, the face detecting mark is read from the flash memory part of the memory; and when the face detecting mark is set as ON, image displaying equipment displays an instruction for promoting the users to lead the face detecting function to be effective.

Description

technical field [0001] The present invention relates to an image pickup device and a control method for image pickup, and more particularly to an image pickup device capable of detecting a face in an image and a control method for image pickup. Background technique [0002] Technologies have been disclosed that detect faces of people in captured images to use data of the detected faces for various applications. Japanese Patent Application Laid-Open No. 2006-87083 discloses a technique of displaying a warning message or automatically changing a control parameter in an imaging unit according to a result output from an object detection device. [0003] As described in Japanese Patent Application Laid-Open No. 2006-87083, in order to keep the object detection apparatus operating full-time, power consumption required for operation and delay in operation due to control burden are caused, which reduces the number of images that can be captured and Increased the inconvenience cause...
