Embodiment
Embodiments of the invention are described with reference to the accompanying drawings.The element of describing in an accompanying drawing of the present invention or a kind of embodiment and feature can combine with element and the feature shown in one or more other accompanying drawings or the embodiment.Should be noted that for purpose clearly, omitted expression and the description of parts that have nothing to do with the present invention, known to persons of ordinary skill in the art and processing in accompanying drawing and the explanation.
Referring to the structural drawing that Figure 1 shows that a kind of embodiment of typoscope of the present invention.This typoscope comprises image collecting device 1 and mark maker 3.Wherein, image collecting device 1 is used for gathering and amplifying the image that comprises literal.Image collecting device 1 can adopt optical amplifier (such as adopting optical lens) and/or circuit to amplify the mode of (as adopting printed circuit board etc.), and the image that comprises literal that gathers is amplified.
Mark maker 3 is used for one or more literal lines of recognition image, and generates the mark that is used for indicating described literal line.When the user moved the picture and text (for example, book made of paper) that need the amplification demonstration, it is mobile together that mark still can be followed the literal line that indicates, thereby can accurately locate current one or several literal line of reading.The quantity of the literal line that indicates can set in advance or can be arranged according to the hobby of oneself by the user.
Owing to have certain line space between the two adjacent style of writing words, in the scope of this line space, without any displaying contents, in an example, mark maker 3 can be identified literal line by representing between two adjacent lines blank in the line space scope in the recognition image.
In an example, mark maker 3 can be presented at the centre position of display device 2 or one or more literal lines of reference position in the recognition image, and generates one or more mark that is used for indicating described one or more literal line.In this example, labeling indicia in other examples, also can be indicated in the literal line of other position in the centre position or one or more literal lines of reference position.
Mark maker 3 also judges whether line feed by the movement of recognition image, and when judging line feed, mark is moved on to the adjacent literal line of current each literal line that is labeled, perhaps with the be separated by literal line of one or more literal lines of current each literal line that is labeled.
In an example, typoscope can comprise display device 2, and enlarged image is shown in the display device 2 to gather image collecting device 1 also, and simultaneously, the mark that mark maker 3 is generated also is shown in the display device 2 together.
In an example, typoscope also can not comprise display device.When typoscope does not comprise display device, the equipment (such as televisor, computer monitor etc.) that typoscope and other can be can be used in demonstration is connected, with the mark that this equipment shows that image collecting device 1 in the typoscope gathers and enlarged image and mark maker 3 generate.
In an example, mark maker 3 is identified the change of described image by the movement of the unique point in the identification literal.For example, extract a plurality of pixels in the literal line as unique point, record the position coordinates of each unique point and the feature of color for example, when image moved, each unique point was also thereupon mobile.A plurality of continuous pixels during unique point is can selected text capable, also can selected text capable in a plurality of discrete pixels.In an example, when judging that the opposite direction of image along the reading direction of literal line Chinese word moves, think that the user is still reading current line, mark maker 3 still carries out mark to the literal line of current institute mark.For example, when literal line is that horizontally-arranged and reading direction are from left to right the time, when judging that image is moved to the left, mark maker 3 still carries out mark to the literal line of current institute mark.
When image moves along the opposite direction of the reading direction of literal line Chinese word first, when then moving along the reading direction of literal line Chinese word, think that the user finishes the reading of current literal line, then read adjacent literal line.This tense marker maker 3 can regenerate new mark adjacent literal line (perhaps current each literal line that is labeled be separated by the literal line of one or more literal lines), to reach the purpose of following the tracks of user's reading content.
Because the typoscope enlargement factor is larger, when the literal in the image is laterally composing, content that generally can't complete demonstration one full line, when the user when reading the latter half of delegation, text carrier need to be moved to the left, be shown to display device 2 or the external equipment that is used for demonstration with the latter half content with delegation.When the user finishes the latter half reading of current line then carries out the reading of next line, text carrier need to be moved right, be shown to display device 2 or the external equipment that is used for demonstration with the first half content with next line.At this moment, just mark need to be moved to next line to follow the tracks of user's reading progress from current reading row.
Thereby in one embodiment, mark maker 3 is identified the line feed of user in reading by the continuous first left and then right movement of recognition image.As a kind of scheme, the method for the first left and then right movement that mark maker 3 recognition images are continuous is divided into following step:
Step 1: extract a plurality of pixels in the literal line as unique point;
Step 2: the relative position relation after relatively more mobile between Characteristic of Image point and the mobile front Characteristic of Image point is judged the moving direction of image;
Step 3: if judge this time mobile direction for left, record is this time mobile so, otherwise record not;
Step 4: judge mobile for the second time direction, if the direction that move the second time is for moving right, then mark maker 3 generates mark at next literal line, otherwise mark maker record this time moves and regenerates mark at current line.
The method of above mark maker 3 identification line feed for be the situation of text composition mode for laterally setting type in the picture and text.Similarly method can be applicable to the situation of text composition mode for vertically setting type in the picture and text, only need make the continuous movement one on the other of mark maker 3 recognition images identify the line feed (row) of user in reading.
In one embodiment, image collecting device 1 can also comprise the input media (not shown).When the user reads the current literal line that is labeled or other users think in the situation about needing, can input line replace command by input media, input media sends to mark maker 3 with this line replace command after receiving line replace command, mark maker 3 moves on to the adjacent literal line of current each literal line that is labeled with mark, perhaps with the be separated by literal line of one or more literal lines of current each literal line that is labeled.The mark that display device 2 update displayed are new.Input media can comprise downwards or the button that makes progress.When the user pressed downward button, mark moved down, and when the user pressed the button that makes progress, mark moved up.The line number that each mark moves can preset or according to being arranged according to the hobby of oneself by the user.
As a kind of embodiment, the image strip that mark maker 3 is stated the pixel with same color in the image by knowledge is identified described blank.In the truth, all there is noise in image, when the judgement of blank, can not accomplish that all pixel color of current line are all identical.When practical operation, the ratio that the pixel that satisfies same color can be accounted for all pixels of current line is regarded as blank line greater than the row of this condition of setting value.Setting value for example can be 99%.
Process flow diagram referring to a kind of embodiment that Figure 2 shows that smart tags method of the present invention.In this embodiment, the smart tags method is divided into following steps:
S1: the image that comprises literal with image collecting device collection and amplification;
S2: the mark maker is identified the one or more literal lines in the described image, and generates the mark that is used for indicating described literal line.
The below is with literal behavior horizontal direction, and is that example is introduced an embodiment of the invention to the situation that the literal line of reference position indicates.Referring to the process flow diagram that Figure 3 shows that a kind of embodiment that the mark maker is identified the literal line that shows in the image.This embodiment is divided into following step:
S21: the mark maker is from the capable high order end of display device any level, displaying contents is carried out horizontal scanning, scanned and move to next line after the delegation and continue scanning, until the pixel of at least two kinds of colors appears in current scan line, note current behavior the 0th row, i.e. N=0;
S22: carry out horizontal scanning to N is capable;
S23: whether all pixels of judging current line are the pixel with same color, if the determination result is NO, then automatically jump to next line, and namely N=N+1 proceeds scanning;
S24: if all pixels of current line all have identical color, the top of then determining current line is literal line and generates mark at current line.
Because in the truth, all there is noise in image, when the judgement of blank, can not accomplish that all pixel color of current line are all identical.When reality was carried out S23, the ratio that the pixel that satisfies same color can be accounted for all pixels of current line was regarded as blank line greater than the row of this condition of setting value.Setting value for example can be 99%.
More than be 3 pairs of a kind of embodiments that show that text is identified of mark maker.Those skilled in the art can carry out random variation to this embodiment as required, for example: behind the execution of step S24, can proceed identification, the row of " lastrow exist pixel and all pixel color of current line of at least two kinds of colors identical " this condition until occur second, the 3rd etc. and satisfy generates mark and shows at current line.That is to say that mark maker 3 can between every style of writing basis shown on the display device, generate a mark.
In addition, the above-mentioned method that the literal line that shows in the image is identified for be that the type-setting mode of the literal line in the picture and text is horizontal type-setting mode.Above method also can be applied in the situation of literal behavior vertical row version mode similarly.In the situation that literal line tilts, utilize above method, might can't find, at this moment can be in step S21, displaying contents is had the scanning at certain angle of inclination, by adjusting the angle of inclination of scanning, can finally identify literal line.
Mark in the embodiments of the invention can be reference line, for example is arranged on the reference line of literal line below, also can be the background color of literal line for example.Mark can be arranged to be convenient to arbitrarily user's identification and not affect the color and style that shows the content of text own.
Adopt typoscope of the present invention and smart tags method, the position of mark can be set according to the picture and text that amplify, and in reading process, mark can be followed the tracks of user's reading progress, thereby bring into play more fully the effect of mark, help the people of low vision to improve its reading efficiency.
In apparatus and method of the present invention, obviously, after can decomposing, make up and/or decompose, each parts or each step reconfigure.These decomposition and/or reconfigure and to be considered as equivalents of the present invention.
