Use transmitter array, one by one the formation method that scans of image segments be from, such as, JP06-214509 document (G09F9/30,1994) known in, but in this existing information source, do not find the above-mentioned whole specific characteristics in the method provided by the invention, so can think that method provided by the invention is creative.
Accompanying drawing is briefly described
Fig. 1 represents that with image division be image segments;
Fig. 2 is illustrated in the object of accepting video information and transmitter array when carrying out relative motion, forms the process of image;
Fig. 3 is illustrated in the object of accepting video information and transmitter array when carrying out relative motion, forms the process of multiple image.
The specific descriptions of embodiments of the invention
Fig. 1 represents two field picture dividing elements one by one.Suppose the relative motion in surface level of the object of accepting video information (such as, the beholder in the railroad car) and imager.Thereby two field picture shown in Figure 1 is divided into vertical unit 1～10.Occasion below, when the relative motion of the object of accepting video information and imager is in the vertical plane (such as, when making the motion of elevator case), above-mentioned image division is a horizontal cell.In all case, all unit have identical size.
The reason of doing like this is can be by identical imager any such elementary area of regenerating.As such imager, in method provided by the invention, adopt transmitter array, its height (in the occasion of the horizontal direction of above-mentioned relative motion) is corresponding with the height of each elementary area.The width of this array can equate with the width of an elementary area, but also can with adjacent several (such as, two) width of elementary area equates.So the size of the array of transmitter is corresponding with the size of the image segments that can comprise one or more elementary areas.
Accepting the occasion that the object of video information (with reference to Fig. 2) and such transmitter array relatively move, transmitter array one after the other makes each image segments in the entire image brighten.If image segments is only formed by an elementary area, then transmitter array one after the other makes these elementary areas 1～10 one by one brighten.If image segments, such as, form by two elementary areas, then transmitter array make simultaneously two adjacent elementary areas (such as, 1 and 2) brighten, following two elementary areas (3 and 4) are brightened, or the like.Yet it does not get rid of following variation, and every pair of possible elementary area is brightened, that is, elementary area 1 and 2 is brightened, and elementary area 2 and 3 is brightened, and elementary area 3 and 4 is brightened, or the like.The selection of the particular transform form that image segments is brightened at first is to determine according to the speed of the object of accepting video information and transmitter array relative motion.In this manner, the direction that brightens (promptly, from elementary area 1 to elementary area 10, or from elementary area 10 to elementary area 1) be unessential, because making process that image segments brightens is enough fast for beholder's eyes, thereby can not feel that different image segments brightens, but feel that entire image brightens.Transmitter array also is unessential according to how long entire image being brightened, but only following aspect is important, when the object of accepting video information is positioned at the viewing area of this transmitter array, above-mentioned image is brightened fully.
Fig. 3 is illustrated in (beholder in the railroad car) motion of the object 14 of accepting video information and by several (is 3 in this occasion) transmitter array 11～13 o'clock, the process of formation multiple image.All arrays 11～13rd, identical, and have similar viewing area.Each array 11～13rd was operated in the following moment, and this moment finger is subjected to the object 14 of video information to enter the viewing area of above-mentioned transmitter array.As shown in Figure 2, carve at this moment, corresponding transmitter array (in this occasion, being the array among Fig. 3 11) beginning one after the other makes the image segments in this two field picture brighten.When the object 14 of accepting video information left the border of the viewing area in the 1st array 11 of transmitter, this array 11 stopped to make above-mentioned image segments to brighten.As long as object 14 enters the viewing area (in this occasion, it is the 2nd array 12 of transmitter) in following an array of transmitter, this array 12 just begins to make above-mentioned two field picture to brighten.
Adjacent transmitter array can make the image of mutual difference and similar frame, (such as, brighten as shown in Figure 3), the quantity that makes the transmitter array that the image of same number of frames brightens is the common quantity by picture frame, the common quantity of the transmitter array in the system, the speed of the object of video information and transmitter array relative motion accepted is determined.
The array transmitter can be by such as, light emitting diode, and laser instrument and other emitter form.Above-mentioned array also can be only formed by a transmitter (such as, gas-filled tube).Before this transmitter, has a row's (many rows) who utilizes machinery or photoelectricity shutter switch hole.The transmitter array of particular form is unessential, and it does not belong to the protection domain of the claim of present patent application.
According to the mode that is equal to; the protection domain of claim of the present invention does not comprise the specific embodiment of following apparatus; this device is used for entering at the object of accepting video information the moment of its viewing area, and is synchronous by the process that independent transmitter array brightens picture frame.These devices can have any embodiment of the synchronizing process that provides required, and particularly, this device can be similar with the device described in the above-mentioned GB1459021A document (G09F19/12,1976).
