In addition, the embodiment of the present invention has more disclosed the display device and the picture regulator that can be used for embodying above-mentioned picture adjusting method.For content of the present invention is more easily understood, below the example that really can implement according to this as the present invention especially exemplified by embodiment.
The functional block diagram that Fig. 1 is the display device that illustrates according to one embodiment of the invention.Please refer to Fig. 1, display device 10 is for example TV (TV) or any display device with menu display function.Display device 10 at least comprises that display module 11, eyesight parameter obtain module 12, distance sensing module 13, adjust parameter generating module 14 and adjusting module 15.
Eyesight parameter obtains module 12 in order to obtain one or more eyesight parameters of user, and the eyesight parameter obtaining is sent to and adjusts parameter generating module 14.Referred in this eyesight parameter can in order to assess described user simple eye/visual capacity (visual ability) of eyes.For example, in the present embodiment, described eyesight parameter can comprise eyesight (visual acuity) number of degrees and/or astigmatism (Astigmatism) number of degrees of user's eyes.Whether the described eyesight number of degrees have the problem of myopia or long sight in order to the eyes of assessing user, and study and judge the degree of myopia or long sight.Whether described astigmatism degree can have astigmatic problem in order to the eyes of assessing user, and studies and judges astigmatic degree.
In the present embodiment, described eyesight parameter can be inputted voluntarily by user.Or in another embodiment, eyesight parameter obtains module 12 also can be according to the identification data corresponding to current user, the mode of tabling look-up with Query Database etc. obtains the eyesight parameter corresponding to current user.In other words, the present invention not limit vision parameter obtain module 12 and obtain the mode of eyesight parameter.About the detailed acquisition mode of eyesight parameter, be detailed later.
For instance, Fig. 2 is the schematic diagram of the distance between the sensing user and the display device that illustrate according to one embodiment of the invention.Please refer to Fig. 2, the distance sensing module (for example, distance sensing module 13) in display device 10 can sensing user 21 and display device 10 between distance (, the first distance) D1.
Adjustment parameter generating module 14 connects respectively eyesight parameter and obtains module 12 and distance sensing module 13, and in order to according to obtaining one or more eyesight parameters of module 12 and the first distance being obtained by distance sensing module 13 from eyesight parameter, produce one or more pictures and adjust parameter.
In the present embodiment, adjusting parameter generating module 14 can, by the mode such as calculating or table look-up, obtain picture and adjust parameter.For instance, in a default algorithm, adjust parameter generating module 14 and can utilize default benchmark eyesight parameter and reference range arrange in pairs or groups the eyesight parameter and the first distance that receive, generation picture adjustment parameter.In more detail, adjusting parameter generating module 14 can be according to the first distance and reference range, produce the first distance and the ratio (being referred to as below the first ratio) of reference range, and according to benchmark eyesight parameter with corresponding to current user's eyesight parameter, produce the ratio (being referred to as below the second ratio) of eyesight parameter and benchmark eyesight parameter.Then, produce picture adjustment parameter according to the first ratio and the second ratio.
In other words, suppose that default reference range is 5 meters, and a default benchmark eyesight parameter is the eyesight number of degrees 1.0.Be that 0.5(represents that current user's the eyesight number of degrees are 0.5 when obtain an eyesight parameter of module 12 from eyesight parameter), and the distance between the user that distance sensing module 13 sensings are current and display device 10 (, the first distance) while being 3 meters, first, adjust parameter generating module 14 by the first distance (, 3 meters) divided by reference range (, 5 meters), and first ratio of generation (, 3/5).Then, adjust parameter generating module 14 by benchmark eyesight parameter (, 1.0) divided by eyesight parameter (, 0.5), and second ratio of generation (, 1.0/0.5).Then, adjust parameter generating module 14 the first ratio (, 3/5) is multiplied by the second ratio (, 1.0/0.5), adjust parameter (, 1.2) and produce picture.
It is worth mentioning that, in another embodiment, adjust parameter generating module 14 and can first produce described the second ratio yet, and then produce described the first ratio, the present invention does not limit the generation order of described the first ratio and the second ratio.In addition, except above-mentioned default algorithm, adjust parameter generating module 14 and can produce adaptively picture by custom or amended various algorithm yet and adjust parameter, the present invention does not limit picture and adjusts calculating and/or the producing method of parameter.
Adjusting module 15 connects display module 11 and adjusts parameter generating module 14, and in order to adjust parameter according to the picture that carrys out self-adjusting parameter generating module 14, adjusts the display frame of display module 11.For example, the above-mentioned example that continues, when adjusting module 15 receives when adjusting parameter and be 1.2 according to the eyesight number of degrees and the first picture of producing of distance, adjusting module 15 can be controlled display modules 11 displaying ratio of display frame entirety is amplified to 1.2 times.Or, adjusting parameter when picture is between 0 to 1 time, represent that the too near and/or user of user distance display device 10 may have the problem of long sight, now adjusting module 15 can be adjusted parameter and dwindle according to this picture the overall displaying ratio of the display frame of display module 11.
In addition, may exceed the indication range of display module 11 after display frame is amplified time, till can display frame being limited to and being amplified to the indication range that meets display module 11 more, or can adjust etc. the multiple amplifying or region according to actual conditions or user's selection, the present invention, not to its restriction, is as the criterion with the demand in practice and/or design.
Particularly, in the present embodiment, adjusting module 15 also can only zoom in or out the part (or being called subregion) of the display frame that shows display module 11, and the regional extent of these subregions also can be adjusted according to demand.Again for example, in one embodiment, suppose that the display frame of display module 11 comprises captions and the image that can present respectively, adjusting module 15 can be respectively by the captions in display frame and/or image zoom or dwindle demonstration.In addition, if captions are amplified to, exceed can indication range and cannot complete demonstration time, captions can be divided into multirow and show.
