Abstract
The invention relates to the field of infrared imaging of mobile phones and relates to a multifunctional mobile phone with an intermediate infrared photographing function. The wavelength range of visible light is from 0.38 micrometers to 0.78 micrometers. Infrared rays are also known as infrared radiation and refer to electromagnetic waves with wavelengths from 0.78 micrometers to 1000 micrometers. Infrared rays with wavelengths from 0.78 micrometers to 2 micrometers are near-infrared rays, and wavelengths of intermediate infrared rays are in a range from 3 micrometers to 5 micrometers. All objects in the nature radiate infrared rays, so that different infrared images can be obtained through measurement of infrared differences between a target and the background by using a detecting instrument. According to the mobile phone, the working wavelength range of an infrared camera is from 3 mu m to 5 mu m, and the resolution ratio of the camera is 320*240. The camera is small in volume, convenient to carry and suitable for assembly on the mobile phone. The infrared photographing is applied on the mobile phone, special requirements of users can be met, and users are greatly facilitated.
Description
Technical field
The present invention relates to mobile phone infrared imaging field, is the mobile phone of infrared photography function in a multi-functional band.
Background technology
The photo that camera imaging obtains, the image that the television camera imaging obtains all are visual light imagings.The wavelength coverage of visible light is 0.38～0.78 micron.Infrared ray claims again infrared radiation, refers to that wavelength is 0.78～1000 micron electromagnetic wave.The part that its medium wavelength is 0.78～2 micron is near infrared, and the wavelength of middle-infrared band is 3～5 microns.Therefore all objects of occurring in nature are infrared radiation all, utilizes detection instrument to measure that infrared ray between and the background of target itself is poor can to obtain different infrared images.The image that Thermal Infra-Red forms becomes thermal map.Infrared thermal imaging makes the surface temperature distribution of the target that human eye can not directly see, becomes the heat picture of the visible representative target temperature profiles of human eye.Do not stopping paying out the ultrared characteristics of penetrating according to all objects, various countries competitively develop various infrared thermal imaging instruments.Texas ,Usa instrument company has successfully developed first generation thermal infrared imaging device in the sixties, is forward-looking infrared system.China also has been developed into REAL TIME INFRARED THERMAL IMAGE imaging model machine at late nineteen eighties and the early 1990s.
Summary of the invention
The mobile phone of infrared photography function in the multi-functional band of the present invention, the infrared camera operating wavelength range of design is 3～5um, camera resolution be 320x240. it to have a volume little, suitable being assemblied on the mobile phone, easy to carry.Photographic IR is applied on the mobile phone, can satisfy people's special requirement, for people bring great convenience.The high-resolution monitoring camera of all angles, and infrared night vision remote monitor shooting are to detection of material object and cache etc.Again can be aspect artistic, what photographic IR brought is diverse visual impact, super real effect.Common photography is carried out under white light conditions.Different therewith, photographic IR is photographed with infrared light supply invisible to the human eye.What visible light photography and human eye were seen is more or less the same, and the effect of non-visible light photography and human eye are seen has very in gap, because infrared penetration is strong, can photograph the clear distant view that exceeds the imagination.
