The simple method is a method for obtaining the full-clear image with the high tolerance level and the large field depth, and the simple method is easy to use and popularize. Little setting or modification is carried out or added in the manufacturing process of an existing shooting device so that more than two times of exposure in different conditions can be continuously carried out in the digital photography shooting process, and obtaining of the true image is achieved.
Description
Technical field:
The present invention relates to a kind of simple and easy real image acquisition methods of photographic scene tolerance, the tolerance technical field of especially relevant photography.
Background technology:
Camera work has experienced the development in more than 100 year, after the outdoor scene tolerance technological invention that in the camera work history, is with historically new significance, just so that photography can the true scene of complete documentation full detail.
Since the technological invention of outdoor scene tolerance, going through for ten several years fails fine universal, can not go beyond as the road that has an obstacle to block the national new technology application of development, the present invention is just in order to allow the combination of outdoor scene tolerance technology and prior art use simple realization, in the method through the problem that is resolved after studying.
Summary of the invention:
In existing camera or video camera, increase the control mode of multiexposure, multiple exposure of different time and the calculating of pixel number, with seldom and very simple improvement just can make it have the simple and easy real image style of shooting of outdoor scene tolerance technology.
Concrete grammar is: the multiexposure, multiple exposure that carries out continuously different condition more than 2 times in the digital photography shooting process, set exposure value or the value condition of color value under the different condition exposure of pixel, and get each pixel exposure value in each exposure and reach the pixel exposure value of setting the value condition, same pixel point is only got once, then the pixel exposure primary system one of having a few is scaled the value of same conditions of exposure, the value of each pixel after the conversion consists of the new image of a width of cloth, it is compressed according to a certain percentage again or is converted to the image that can show.
Different condition be change in aperture and focal length focus and zoom and eyeglass and time for exposure and the sensor devices etc. one or more or whole, can be provided with certain proportionate relationship between the different condition of each exposure or set a plurality of different multiples relations, or each exposure only changes one, exposure frequency is more than 2 times or 2 times, namely can behind single exposure, continue exposure, also can behind single exposure, restart exposure.
In the digital photography shooting process, carry out continuously the multiexposure, multiple exposure of different condition more than 2 times, the order of exposure was carried out to long-time order by the short time, or by carrying out to the short time order for a long time, or by the exposure of carrying out again the different time between 2 time after 2 different time exposures, with single exposure centered by the time or benchmark carry out to long-time and short time, or each fixed mode of all carrying out with fixing time for exposure and the order of fixing and fixing exposure frequency, fixed mode can be provided with one or more, or fixing one or more in time for exposure and exposure order and the exposure frequency only, and in shooting process with literal and sound with or the mode such as image inform the cameraman.
In the digital photography shooting process, carry out continuously the multiexposure, multiple exposure of different condition more than 2 times, set the exposure value of pixel or the value condition of color value, the value condition of setting can be the span of exposure value or color value, being set as between exposure value or the color value 0-100% of scope is not 0 and 100% any range, how much relevant the setting of span is with the conditions of exposure change, the more at most span that changes is larger, 100%～median once between exposure value or color value got 0～100%, median～median n time, median～0 once, n 〉=0 wherein.
In the digital photography shooting process, carry out continuously the multiexposure, multiple exposure of different condition more than 2 times, the above image of two width of cloth of finishing, same pixel repeatedly reach span get the earliest once or reach once higher in the span, maybe can set one or more exposure values and get immediate value, the same pixel of pixel that does not reach span is got once immediate value, or it is once higher to get exposure value, maybe can set one or more exposure values and get immediate value, or according to the priority value of setting in the conditions of exposure.
In the digital photography shooting process, carry out continuously the multiexposure, multiple exposure of different condition more than 2 times, short time is taken a width of cloth image before taking, or with in the shooting process for the first time the image of exposure as taking foundation, calculate each pixel exposure value and reach the condition that setting range needs, calculate the number of times of needs exposure and total shooting time and each condition of exposing according to these conditions, again these results are informed the cameraman.
Carry out continuously the multiexposure, multiple exposure of different condition more than 2 times in the digital photography shooting process, the obtained data of its multiexposure, multiple exposure are buffered in the buffer jointly, store in the memory together behind all end exposures again.
In the digital photography shooting process, carry out continuously the multiexposure, multiple exposure of different condition more than 2 times, the single exposure of maximum duration wherein, can preserve all data, make a kind of of reference image that present digital equipment can show to provide immediately, and provide contrast and reference for the image of multiexposure, multiple exposure data after merging.
In the digital photography shooting process, carry out continuously the multiexposure, multiple exposure of different condition more than 2 times, the condition of the simultaneously each exposure of record, and which time exposure the exposure value of image slices vegetarian refreshments is taken from.
Carry out continuously the multiexposure, multiple exposure of different condition more than 2 times in the digital photography shooting process, the value condition of setting pixel is clearly pixel of exposure focus, and the value condition of setting also can be in the setting span of exposure value or color value.
In the digital photography shooting process, carry out continuously the multiexposure, multiple exposure of different condition more than 2 times, the condition that the setting of conditions of exposure can be fit to according to different focus images, and different focus image can carry out the exposure of different time more than 2 times.
In the digital photography shooting process, carry out continuously the multiexposure, multiple exposure of different condition more than 2 times, the image that long burnt maximum multiple is taken with original size as intermediate image, the image of wide angle shot is amplified to the back of setting off behind the same multiple of long burnt maximum multiple in intermediate image, when taking the image of a plurality of different zooms, order sets off the back in intermediate image successively, and wherein the image of maximum wide-angle sets off in the end face.
Embodiment:
In existing camera or video camera, increase the control mode of multiexposure, multiple exposure of different time and the calculating of pixel number, with seldom and very simple improvement just can make it have the simple and easy real image style of shooting of outdoor scene tolerance technology.
The invention is not restricted to camera or video camera, be equally applicable to the image processing software of various image processing equipments and scope and computer, and relevant equipment and program.
