Also it should be noted that, terminal in the embodiment of the present invention includes but not limited to the digital camera with shooting and camera function, slr camera, smart mobile phone, panel computer, media player, intelligent television, Intelligent bracelet, Intelligent worn device, MP3 player (Moving Picture Experts Group Audio LayerIII, dynamic image expert compression standard audio frequency aspect 3), MP4 (Moving Picture Experts GroupAudio Layer IV, dynamic image expert compression standard audio frequency aspect 3) player, personal digital assistant (Personal Digital Assistant, PDA) photographing device such as pocket computer on knee and desktop computer.
In the present invention by main to be described with shooting and the smart mobile phone of camera function, but do not represent terminal of the present invention and be only defined in making a video recording and the smart mobile phone of camera function.
Fig. 1 is the schematic flow sheet of a kind of photographic method in the embodiment of the present invention, describe in detail below in conjunction with a kind of photographic method in accompanying drawing 1 pair of embodiment of the present invention, as shown in Figure 1, a kind of photographic method in the present embodiment can comprise the following steps S101-step S104.
Step S101: receive camera open command, obtained the infrared thermal imaging picture of shooting area by infrared thermal imaging camera.
Particularly, after the camera open command receiving smart mobile phone, obtained the infrared thermal imaging picture of shooting area by infrared thermal imaging camera shooting.Because human body is a natural bio-red external sort algorithm, can constantly launch towards periphery and absorb infrared radiation, and the Temperature Distribution of normal human has certain stability and characteristic, according to this principle, by the human infrared radiation in thermal imaging camera collection shooting area, and be converted to digital signal, form pseudo-color thermal map, just define the infrared thermal imaging picture of final shooting area.
It should be noted that, the infrared thermal imaging camera in the present invention can be positioned in terminal, also can be positioned on other terminal equipment of carrying out with terminal camera connecting and binding.When in same terminal, can by not only installation infrared thermal imaging camera but also install the mode of common camera on the same position of terminal, take rotation to make a video recording the method for taking pictures during use, the shooting area that can realize two different cameras is consistent; When not in same terminal, as long as be interconnected cooperation, be consistent by adjustment angle or position to the shooting area making two cameras obtain.Namely the present invention does not do concrete restriction to the particular location of the camera of infrared thermal imaging camera and terminal and implementation; as long as the shooting picture that infrared thermal imaging camera obtains with the camera of terminal is consistent; and can communication be interconnected, all belong to the scope that protection is contained in the present invention.
Step S102: search the target area in described infrared thermal imaging picture, obtains and finds the relative position of described target area in described shooting area.
Particularly, because the photographic subjects in the present invention comprises at least one in personage or animal, and the Temperature Distribution of normal human has certain stability and characteristic, the infrared thermal imaging formed differs from landscape or the environment of surrounding, according to this principle, can by the infrared thermal imaging picture searching of shooting area in step S101 in this infrared thermal imaging picture with the target area of human or animal, according to the thermal imaging distribution situation on picture, obtain the coordinate of this target area, calculate the coordinate information of the relative position of target area in shooting area.
Step S103: with described relative position for focal point control terminal camera is focused.
Particularly, according to the coordinate information of the relative position of target area in shooting area of the acquisition in step S102, the target area of searching in the shooting area of terminal camera is calculated with the coordinate information of relative position, with this relative position for focus, the camera of terminal is focused, and focus drops on this relative position the most at last.It should be noted that, this relative position refers to the band of position in shooting area or position range, is not limited to concrete certain a bit.
Step S104: receive photographing instruction and take pictures.
Particularly, after focusing step completes, the photographing instruction that just can receive user is taken pictures, or terminal self carries out automatic camera automatically.
Further, the inventive method also can be applied to when the data of number information and the user preset in the infrared thermal imaging picture of monitoring or content do not conform to, then carry out reporting an error and generate to report an error and to remind or automatic rotation rotatable camera carries out the adjustment of image content.Will be understood that, also can judge to obtain photographing objective whether in camera lens, if not in camera lens, then can be rotated by the angle of adjustment rotatable camera, make photographing objective in camera lens to focus and take pictures.Further, can be different according to each spot temperature of body, define different thermal fields., focus area is arrived surely certain position concrete of human body or animal.
The embodiment of the present invention, by in photographic method, utilize infrared thermal imaging camera to obtain the infrared thermal imaging picture of shooting area, search and obtain the relative position of target area in shooting area, finally with this relative position for focal point control terminal camera carries out focusing and taking pictures.Achieve and utilize infrared thermal imaging principle accurately to focus to the personage be taken or animal, solve when taking illumination condition and being poor, camera cannot auto-focusing thus cause the unsharp problem of photographic subjects, save time and the step of user's manual focus, effectively improve take pictures efficiency and shooting quality, improve Consumer's Experience.
