Description
Technical field
The utility model relates to a kind of image pick-up device white balance colour examining temperature device, espespecially a kind of image pick-up device as the camera lens light source passage of the mobile phone of camera, video camera and tool camera function or panel computer in or in fuselage, be provided with an independent white or grey light transmission piece and temperature sensing element of the same colour after white or grey light transmission piece, to obtain colour temperature numerical value accurately, make the photo of shooting or the color of image reach the white balance colour examining temperature device that very approaches object with floor primary colors.
Background technology
At present because business progress drives of prosperous economy, and then promoted people's quality of life, except clothing, food, live, outside row, tourism and stress-relieving activity have become one of main project of modern's pressure relief, therefore, people are in order to keep the various memories in daily life here, big city is used camera, video camera or camera cell phone are taken, in addition, also comprise wedding photo and conventional camera or the video camera of Professional Photography in business, but great majority have identical sensation per capita, be camera and the video camera of current commercially available various brands, how high its pixel of no matter claiming its CCD or CMOS have, or how senior its built-in processor (CPU) have, its the color of the photo of taking or film often variant with the on-the-spot primary colors of taking thing, although the camera of current commercially available various brands, video camera or camera cell phone, the mostly built-in function of Automatic white balance, for improving colour cast, have greatly improved, but the scene when taking is all different, and often have the hybrid light source of multiple different scene colors, when this hybrid light source enters in camera or video camera, the built-in white balance of camera is processed and only can be simulated approximation, and the cross-color of captured photo or film and on-the-spot primary colors are not inconsistent, and white balance is so-called colour temperature, colour temperature is exactly luminous object by the red composition to comprising color in white temperature at different levels institute ray, colour temperature can affect the sensation of a photo, in the morning or the photo of taking dusk can be partially red, the color of taking pictures under tungsten light can be partially yellow, these phenomenons are all the colour casts producing because colour temperature at that time can not meet the colour temperature standard of film.
Therefore, the problem of white balance is real is at present common people's puzzlement, professional photographer's a difficult problem particularly, though professional photographer has the auxiliary of various software, but the correction for white balance often allows it expend much time and energy, therefore, professional photographer is when taking, except needing to use the advanced circumstances in which people get things ready for a trip temperature detector of expensive colour examining temperature instrument (colorimeter or color meter) to survey so that camera or video camera are carried out colour temperature adjustment, also with multi-section camera or video camera, the environment that first first carries out next photographed scene by assistant with colorimeter carries out colour temperature detection, and the color temperature value of good each camera of first adjustment or video camera, to save the time of photography, but its process quite bothers, and the appropriate litigation fees of cost purchase of equipment is high.
Existing image pick-up device, independently WHITE TONE induction installation is not set, mainly by colour temperature default value or CCD(CMOS) on-the-spot light source is read after, light source is analyzed to numerical value transfers to primary processor CPU to carry out Automatic white balance (the AWB:Auto White Balance) computing of colour temperature analog computation, when changeful or shortcoming pure white standard as complicated in on-the-spot light source and environmental colors is got look, its Automatic white balance colour temperature logical operation is often error just, and takes photograph or the film of colour temperature incorrect (being cross-color).
And the correct colour temperature of the photographic scene of on-the-spot light source and color complexity is not more that on image pick-up device, simple colour temperature default value (fine day, rainy day, dusk, incandescence, fluorescence etc.) can be dealt with and takes photograph or the film that colour temperature (color) is correct.
Comprise that at present five-star S.L.R or video tape recorder rely on RGB photoreceptor sensor completely or shade photoreceptor image sensor does the reckoning of light source color temperature logic, but often computing unsuccessfully can not obtain accurately on-the-spot colour temperature in real time, and takes color get out of tune photograph and the film of distortion.
The white light that utilization is filtered or neutral ashen light and independent colour examining temperature device are measured the correct color temperature value of floor, so just can solve the problem that photograph or film color get out of tune distortion and fail effectively to solve always completely.
Utility model content
The utility model research people is because above-mentioned existing camera, the mobile phone of video camera and tool camera function, panel computer cannot accurately produce the white balance (colour temperature) of standard and make practicality puzzlement and the shortcoming to be improved that the color of captured photo or film cannot be true to nature when taking, expect a breakthrough design can be provided, to promote practical function, be to grind with great concentration think of, design team's system, the comprehensive achievement of being engaged in for many years specialized technical knowledge and practical experience and the design gained of Related product design production and marketing, work out eventually the utility model-a kind of image pick-up device white balance colour examining temperature device, to offer user.
