Abstract
The invention relates to a myopia-preventing electronic device, which comprises a digital automatic focusing camera, a display screen, an audio amplifier, a microprocessor chip and a function module, wherein the digital automatic focusing camera is positioned above the display screen, and automatically measures and calculates a distance f between a shot object and a lens; the function module is arranged on the microprocessor chip; and the microprocessor chip reads the f which is measured and calculated by the digital automatic focusing camera by running the function module, compares the read f with a normal value set in the function module, and controls the display screen and the audio amplifier by running the function module, thereby monitoring whether the distance between the shot object and the lens is proper or not, giving a prompt and preventing myopia. The myopia-preventing electronic device is favorable for cultivating good learning and reading habits of users, particularly students, and effectively decreasing the probability of the myopia.
Description
Technical field
The present invention relates to a kind of myopic-preventing electronic installation.
Background technology
Students in middle and primary schools' eyesight myopia incidence rises year by year, and main cause is the overlong time of doing the homework of reading a book, and eyes and books or homework book hypotelorism cause.In the face of three one-tenth in present primary school, junior middle school fifty percent, the student eyesight rate of myopia of senior middle school more than seventy percent, the good way with the eye custom of forming that the teacher and the head of a family stress always for many years seems unable to do what one wishes.Pass through technological approaches; If the time span that can find effective method monitoring student's eyes and homework book books distance and use eye continuously; And in time remind and prevent, this will solve the serious day by day near-sighted problem of students in middle and primary schools and reduce myopia on technological layer incidence.
Summary of the invention
In order to overcome above-mentioned technical barrier, the invention provides a kind of myopic-preventing electronic installation, be used for monitoring and when correcting the student written industry or reading textbook incorrect with eye distance from and with between at the moment.
Major technique of the present invention thes contents are as follows:
A kind of myopic-preventing electronic installation comprises digital AF camera, display screen, note amplifier, microprocessor chip, functional module; Said digital AF camera is positioned at the display screen top; Said digital AF camera calculate automatically between subject and the camera lens apart from the f value; Said functional module is installed on the microprocessor chip; Said microprocessor chip reads the f value that the digital AF camera calculates through the operation function module; Be set in the normal value in the functional module through comparison, come display screen and note amplifier are controlled through the operation function module then, thereby monitor, remind and prevent whether the distance between subject and the camera lens is suitable.
Functional module on the above-mentioned microprocessor chip is controlled display screen and note amplifier and is comprised following flow process:
(1) if the f value that reads less than the normal value of setting, is sent following alert news through functional module to display screen and note amplifier in order:
A, send voice messaging prompting through note amplifier;
B, through display screen display font on screen, use the mode of vibrations or light flicker to remind subject to increase the distance between shot object and the camera lens;
C, display screen are forced the blank screen some time;
Above-mentioned alert news b sends back f value at alert news a just to take place after still greater than the normal value of setting, above-mentioned alert news c be alert news b send back f value still greater than the normal value of setting after just generation;
(2) if the f value that reads is equal to or greater than the normal value of setting, note amplifier does not send voice messaging, and display screen shows normal;
(3), in functional module, set the value of a set time, if the f value that reads is equal to or greater than time of normal value of setting above the value of set time, display screen and note amplifier are sent following alert news in order through functional module:
D, send voice messaging through note amplifier, prompting will be forced blank screen;
E, through display screen display font on screen, prompting will be forced blank screen;
F, display screen are forced the blank screen some time.
By technique scheme, the present invention has advantage at least:
The application of the invention will help to cultivate people particularly student's better learning and reading habit, reduce near-sighted odds effectively.
Embodiment of the present invention is provided by following examples and accompanying drawing thereof in detail.
