Problems solved by technology

[0004] However, the technique described in the aforementioned Japanese Patent Laid-Open No. 2004-40491 analyzes the shooting scene based on the face, and as a result, it is not a proposal for optimal camera control.
[0005] In addition, the technology described in the above-mentioned Japanese Patent No. 2627483 is not a technology related to photography by a camera, and the structure of the device is also large-scale

no. 1 Embodiment approach

[0034] figure 1 It is a block diagram showing the basic configuration of the camera according to the first embodiment of the present invention. The camera has: a main CPU (hereinafter referred to as MPU) 11; a plurality of switches 11a, 11b, 11c; a signal processing unit 12; a face detection unit 13; an outline detection unit 14; a flash ROM 15; an auxiliary light irradiation unit 16; 18; zoom control section 19; analog front end section (AFE, analogfront end) 21; SDRAM 22; memory 23; microphone 24; speaker 26; display section 27; print signal output section 28; wireless communication section 29; imaging element 31; photographic lens32.

[0035] exist figure 1 Among them, the MPU 11 having functions as a control unit and a determination unit is constituted by a microcontroller or the like, is connected to the switches 11a, 11b, and 11c, and detects various user operations based on the states of the switches 11a, 11b, and 11c. Further, the MPU 11 sequentially controls each c...

no. 2 Embodiment approach

[0089] Next, a second embodiment of the present invention will be described.

[0090] Furthermore, in the second embodiment described below, the basic structure of the camera is the same as that of the first embodiment described above, and in order to avoid repeated descriptions, the same reference numerals are assigned to the same parts, and their illustrations and descriptions are omitted. Only the different parts are described.

[0091] Figure 10 It is a flowchart for explaining the shooting operation of the camera according to the second embodiment of the present invention.

[0092] In this second embodiment, based on the operation of determining the skin color of the subject based on the result of face detection at the time of shooting (or before it), the skin color part other than the face and whose size is about half the size of the face is determined as the palm. (or the back of the hand). The determination of skin color is based on the color information of the ima...

no. 3 Embodiment approach

[0109] Next, a third embodiment of the present invention will be described.

[0110] In addition, in the third embodiment described below, the basic structure of the camera is the same as that of the above-mentioned first embodiment and second embodiment, so in order to avoid duplication of description, the same reference numerals are given to the same parts and omitted. The illustrations and descriptions only describe the different parts.

[0111] The techniques proposed in the first embodiment and the second embodiment can be effectively used in a case where only an image capturing a scene with good timing is retained from among a plurality of images obtained by repeated high-speed shooting.

[0112] However, from the moment the image is captured to the display and determination of the shot, if Figure 15 A time of Δt2 is required as shown. At this time, if the best timing to start shooting is determined based on the criteria of the captured image, the shooting timing is a...

Abstract

There is disclosed a camera which detects a face portion of a subject from a shot image to determine whether a shot image is a good shot candidate image from the features of the face portion and a face portion-related image portion. As examples, the features include, but not be limited to, (1) the shape and variation in contour ranging from the vicinity of the face portion, (2) the position of a hand or leg to be determined by similarity to the skin tone of the face portion, and (3) determination made from the detection result of the face portion as to whether the subject is a half-length or full-length figure.

Description

technical field [0001] This invention relates to improvements in digital cameras, and more particularly to cameras that allow fewer failed photographs to be taken. Background technique [0002] Techniques for detecting and utilizing human faces from images are well known. For example, Japanese Patent Application Laid-Open No. 2004-40491 proposes to use the size of the face to determine the distance between the subject and the device, and to switch the volume level. In addition, cameras that control focus and exposure for faces in images are also being sold. [0003] Furthermore, a technique for detecting a person's posture is also known (for example, refer to Japanese Patent No. 2627483). [0004] However, the technology described in the aforementioned Japanese Patent Application Laid-Open No. 2004-40491 analyzes the shooting scene based on faces, and as a result, it is not a proposal for optimal camera control. [0005] In addition, the technology described in the aforem...
