In the embodiment of the present invention, can determine described the first color that needs correction with respect to described first user, determine the described first area at described the first color place, after extracting all pixels in described first area, can proofread and correct the pixel extracting, can obtain the image information without dyschromatopsia.So, what after proofreading and correct, show can be still coloured image, can not lose colouring information, and color is proofreaied and correct, for having the user of dyschromatopsia, still can normally watch, and without changing by hardware switch, system can complete color correction automatically, improve correction efficiency, also improved demonstration accuracy.

Referring to Fig. 1, in the embodiment of the present invention, show that the main flow process of bearing calibration is as follows:

Step 101: determine that by judging at least one first color, described the first color are the color that needs correction with respect to first user.

Can first determine described the first color by judgement.For example, can provide dyschromatopsia discriminant information to described first user, to determine described at least one first color of described first user None-identified by the selection of described first user.

For example, described dyschromatopsia discriminant information can be secondary or several dyschromatopsias differentiation patterns, system is differentiated patterns for user shows this pair or several dyschromatopsias, to allow described first user select, thereby can approximately know whether described first user suffers from dyschromatopsia and suffer from the dyschromatopsia of which type, to determine described the first color.Or described dyschromatopsia discriminant information can be also whole chromatogram image, system is described whole chromatogram image for user shows, is its None-identified thereby can allow described first user select the chromatogram in which region in the whole chromatogram image showing.

For example, described first user is in the time of login system, system can provide described dyschromatopsia discriminant information from first user described in trend, or, described first user can move a software in system, this software can be for providing described dyschromatopsia discriminant information to described first user, or, described first user can obtain the described dyschromatopsia discriminant information that system provides by triggering a specific keys, or described first user also can obtain described dyschromatopsia discriminant information by other means.

In the embodiment of the present invention, described the first color can be a kind of, can be also multiple, is at least a kind of.

Step 102: determine at least one first area corresponding to described at least one the first color in content to be displayed.

Determining after described the first color, can continue to determine the described first area corresponding to described the first color in described content to be displayed.Wherein, can have one at least corresponding to a kind of described first area of described the first color.In the embodiment of the present invention, stipulate to only include a kind of color in a described first area.

In the embodiment of the present invention, for example user has opened a secondary picture, and this picture is described content to be displayed, and system can be determined at least one first area corresponding to described at least one the first color in this picture.

For example, described in the present embodiment, the first color has two kinds, is respectively red and green, in this picture, has two corresponding to red region, have one corresponding to green region, system can determine that in this picture, the described first area corresponding to these two kinds of described first colors has three.

In the embodiment of the present invention, can also be according to described content to be displayed zones of different for user's vision severity level to described content to be displayed prioritization.For example, if user watches a secondary picture, this picture is personage's picture, in this picture the region at personage place for user's vision severity level can be higher than the region at scenery place the vision severity level for user, in this picture, the priority in the region at personage place can be higher than the priority in the region at scenery place.Can also divide more detailed, for example, in the region at personage place, the region at place, face position is higher for user's vision severity level than the region at other places, position of health, the priority in the region at place, face position can be higher than the priority in the region at other places, position of health, etc., the concrete priority criteria for classifying can be preset by system, or also can be stipulated voluntarily by user.

In the embodiment of the present invention, if described content to be displayed has been divided to priority, before step 102, can also first determine the highest first content of described content to be displayed medium priority, like this, in the time of described at least one first area of determining in described content to be displayed corresponding to described at least one the first color, specifically can determine described at least one first area corresponding to described at least one the first color in described first content.Described at least one first area of described at least one the first color that only the definite the highest content of priority of need comprises, and can not consider for the content of low priority, can only proofread and correct the highest content of priority at timing, without the content of proofreading and correct low priority, so both can further improve correction efficiency, and user's focus is mainly the content of high priority, even the content of low priority is not processed, for user, impact is also little.

Or, in the embodiment of the present invention, if described content to be displayed has been divided to multiple priority, before step 102, can determine that front M forward priority of described content to be displayed medium priority distinguishes corresponding described first content, M is positive integer, like this, in the time of described at least one first area of determining in described content to be displayed corresponding to described at least one the first color, specifically can determine described at least one first area corresponding to described at least one the first color in described first content.Described at least one first area of described at least one the first color that only the definite higher content of priority of need comprises, and can not consider for the content of low priority, can only proofread and correct the higher content of priority at timing, without the content of proofreading and correct low priority, so both can further improve correction efficiency, and user's focus is mainly the content of high priority, even the content of low priority is not processed, for user, impact is also little.The value of concrete M can be by default, or also can be set voluntarily by user.

Step 103: extract all pixels in described at least one first area.

Behind described at least one first area of determining corresponding to described at least one the first color, can extract respectively all pixels in described at least one first area.

For example, have 2 if determined corresponding to the described first area of described at least one the first color, can extract respectively included all pixels in these two described first areas.

Step 104: according to zones of different corresponding to each pixel extracting, all pixels that extract are proofreaied and correct, to obtain the image information without dyschromatopsia.

During because of extraction pixel, be the pixel extracting respectively according to different described first areas, therefore each pixel can be unique corresponding to a described first area., for all pixels that extract, can build first matrix from a described first area, the quantity of described the first matrix can be identical with the quantity of described first area, and described the first matrix can be corresponding one by one with described first area.

For example, the described first area quantity of determining is 2, be respectively first first area and second first area, from described first first area, extract N pixel, this N pixel entirety is called pixel A, from described second first area, extract P pixel, this P pixel entirety is called pixel B, can build first the first matrix according to described pixel A, can build second the first matrix according to described pixel B, the quantity of described first area is 2, the quantity of described the first matrix is also 2, and described the first matrix is corresponding one by one with described the second matrix.

Building after described at least one first matrix, described at least one first matrix can be transformed into LMS space, obtain at least one second matrix.

In the embodiment of the present invention, for example, build 3 described the first matrixes, can respectively described the first matrix in these 3 rgb spaces be transformed into LMS space, obtained 3 described the second matrixes.

Wherein, LMS is the color space take the spectral response amounts of three cone cells as benchmark, and LMS represents that respectively vision medium wavelength is the light wave (Long, medium, short) of long, medium and short.

In general, be transformed into LMS space from rgb space, can first RGB be converted into the XYZ space of CIE, and then be converted into LMS space.Concrete:
