Embodiment
With reference to the accompanying drawings embodiments of the invention are described.The element described in an accompanying drawing of the present invention or a kind of embodiment and feature can combine with the element shown in other accompanying drawing one or more or embodiment and feature.It should be noted that for purposes of clarity, accompanying drawing and eliminate expression and the description of unrelated to the invention, parts known to persons of ordinary skill in the art and process in illustrating.
Shown in Figure 1 is the structural drawing of 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 for gathering and amplifying the image comprising word.Image collecting device 1 can adopt optical amplifier (such as adopting optical lens) and/or circuit to amplify the mode of (as adopted printed circuit board etc.), amplifies the gathered image comprising word.
Mark maker 3 for the one or more literal lines in recognition image, and generates the mark for indicating described literal line.When user moves picture and text (such as, book made of paper) needing to amplify display, mark still can be followed indicated literal line and be moved together, thus accurately can locate one or several current read literal line.The quantity of the literal line indicated can pre-set or can be arranged according to the hobby of oneself by user.
Owing to there is certain line space between adjacent two style of writing words, in the scope of this line space, without any displaying contents, in an example, mark maker 3 and can identify literal line by the blank represented in recognition image between two adjacent lines within the scope of line space.
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 recognition image, and generates one or more mark for indicating one or more literal line described.In this example, labeling indicia, at one or more literal lines of centre position or reference position, in other instances, also can be indicated in the literal line of other 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 be labeled, or to be separated by the literal line of one or more literal line with current each literal line be labeled.
In an example, typoscope can comprise display device 2, is shown in display device 2, is also shown to together in display device 2 by the mark that mark maker 3 generates meanwhile image collecting device 1 to be gathered also enlarged image.
In an example, typoscope also can not comprise display device.When typoscope does not comprise display device, the equipment (as televisor, computer monitor etc.) that typoscope and other can be can be used in show is connected, and gathers and the mark of enlarged image and the generation of mark maker 3 with the image collecting device 1 that this equipment shows in typoscope.
In an example, maker 3 is marked by identifying that the movement of the unique point in word identifies the change of described image.Such as, extract multiple pixels in a literal line as unique point, record the position coordinates of each unique point and the feature of such as color, when image moves, each unique point also moves thereupon.Unique point can selected text capable in multiple continuous print pixel, also can selected text capable in multiple discrete pixel.In an example, when judging that the opposite direction of image along the reading direction of word in literal line moves, think user still at reading current line, mark maker 3 still marks current marked literal line.Such as, when literal line be horizontally-arranged and reading direction be from left to right time, when judging that image is moved to the left, mark maker 3 still current marked literal line is marked.
When image first moves along the opposite direction of the reading direction of word in literal line, then along when the reading direction of word moves in literal line, think that user completes the capable reading of current character, then read adjacent literal line.This tense marker maker 3 can regenerate new mark, to reach the object of following the tracks of user's reading content in adjacent literal line (or current each literal line be labeled be separated by the literal line of one or more literal line).
Because typoscope enlargement factor is larger, when the word in image is horizontal typesetting, generally cannot the content of complete display one full line, when user is when reading the latter half of a line, need text carrier to be moved to the left, so that the latter half content of a line is shown to display device 2 or external being used in the equipment shown.When the latter half that user completes current line is read then carries out the reading of next line, need text carrier to move right, so that the first half content of next line is shown to display device 2 or external being used in the equipment shown.Now, just need mark to move to next line to follow the tracks of the reading progress of user from current reading row.
Thus, in one embodiment, mark maker 3 and identify the line feed of user in reading by the movement that recognition image continuous print is first left and then right.As a kind of scheme, the method for the movement that mark maker 3 recognition image continuous print is first left and then right is divided into following step:
Step one: extract multiple pixels in a literal line as unique point;
Step 2: the relative position relation between the unique point of relatively more mobile rear image and the unique point of mobile front image judges the moving direction of image;
Step 3: if judge that the direction of this time movement is for left, so record this time moves, otherwise not record;
Step 4: the direction judging second time movement, if the direction of second time movement 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.
Above mark maker 3 identify the method for line feed for the situation of to be text composition mode in picture and text be horizontal typesetting.The similar method text composition mode that can be applicable in picture and text is the situation of longitudinal typesetting, and the movement one on the other of mark maker 3 recognition image continuous print only need be made to identify that user changes row (column) in reading.
In one embodiment, image collecting device 1 can also comprise input media (not shown).When user reads the current literal line be labeled or other users think need when, line replace command can be inputted by input media, after input media receives line replace command, this line replace command is sent to mark maker 3, mark is moved on to the adjacent literal line of current each literal line be labeled by mark maker 3, or to be separated by the literal line of one or more literal line with current each literal line be labeled.Display device 2 upgrades the new mark of display.Input media can comprise button or upwards downwards.When user presses downward button, mark moves down, and when user presses button upwards, mark moves up.The line number of each mark movement can preset or arrange according to the hobby of oneself according to by user.
As a kind of embodiment, mark maker 3 identifies described blank by knowing the image bar with the pixel of same color stated in image.In 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 row that the ratio that the pixel meeting same color can be accounted for all pixels of current line is greater than this condition of setting value regards as blank line.Setting value can be such as 99%.
Shown in Figure 2 is the process flow diagram of a kind of embodiment of smart tags method of the present invention.In this embodiment, smart tags method is divided into following steps:
S1: also amplify the image comprising word with image acquisition device;
S2: the one or more literal lines in image described in the identification of mark maker, and generate the mark for indicating described literal line.
Below with word behavior horizontal direction, and be that example introduces an embodiment of the invention to the situation that the literal line of reference position indicates.It is shown in Figure 3 for mark maker is to the process flow diagram of a kind of embodiment that the literal line in display image identifies.This embodiment is divided into following step:
S21: mark maker is from the high order end that display device any level is capable, horizontal scanning is carried out to displaying contents, moves to next line after having scanned a line 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: horizontal scanning is carried out to N-th row;
S23: whether all pixels judging current line are the pixel with same color, if judged result is no, then automatically jump to next line, i.e. N=N+1, proceeds scanning;
S24: if all pixels of current line all have identical color, then determine that the top of current line is literal line and generates mark at current line.
Due in 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 performs S23, the row that the ratio that the pixel meeting same color can be accounted for all pixels of current line is greater than this condition of setting value regards as blank line.Setting value can be such as 99%.
More than for marking a kind of embodiment that maker 3 identifies display text.Those skilled in the art can carry out random variation to this embodiment as required, such as: after execution of step S24, can proceed to identify, until appearance second, the 3rd etc. meets the row of " lastrow there is the pixel of at least two kinds of colors and all pixel color of current line are identical " this condition, generate at current line and mark and show.In other words, between the often style of writing basis that mark maker 3 can be shown on the display apparatus, a mark is generated.
In addition, above-mentioned to the literal line in display image carry out knowing method for distinguishing for be the type-setting mode of literal line in picture and text be horizontal type-setting mode.When above method also can be applied to word behavior vertical row version mode similarly.When literal line tilts, utilize above method, likely cannot find, at this moment in the step s 21, the scanning at certain angle of inclination can be had to displaying contents, by the angle of inclination of adjustment scanning, finally can identify literal line.
Mark in embodiments of the invention can be reference line, such as, be arranged on the reference line below literal line, also can be the background color of such as literal line.Mark can be arranged to be convenient to arbitrarily user and identify and the color and style not affecting the content of display text own.
Adopt typoscope of the present invention and smart tags method, can arrange the position of mark according to the picture and text amplified, in reading process, mark can follow the tracks of the reading progress of user, thus play the effect of mark more fully, help the people of low vision to improve its reading efficiency.
