Description
Technical field
Relevant a kind of control system of the present invention and method thereof, particularly a kind of control system of display device and method that is applicable to photographic goods to reduce the required electric power of display device, improves electricity usage efficient.
Background technology
Recently digital camera replaces traditional camera and is used at large in modern's the life, is not only because the photo data of digital camera is preserved easily, and factor word camera operation makes things convenient for and can meet the multi-functional demand of modern especially.The pre-viewing system of one electronics has been set mostly to read photographic picture in digital camera, function class is like the optics picture window of traditional S.L.R.The pre-viewing system of known electronics is that (Thin FilmTransistor Liquid Crystal Display is TFT-LCD) so that the picture of instant playback phtographic lens institute desire photography for colorful film transistor liquid crystal display (TFT-LCD) of device.Yet because the Via Color TFT-LCD required electric power is high, so provide the operation interface of closing the pre-viewing system of electronics for the electric power long enough time is taken, and having a kind of brilliance control interface to control Via Color TFT-LCD brightness so that the user to be provided, the control by brightness is to reduce the power consumption of Via Color TFT-LCD.
But needing the control mode of the different Via Color TFT-LCD brightness of manual adjustment is very inconvenience in different external light source brightness for most user, if then can cause the trouble in the use when the shade intersection is photographed back and forth, therefore most user still is a burden unnecessary when Via Color TFT-LCD is controlled at maximum brightness with the minimizing photography.
In addition, a kind of sleep mode that uses is also arranged to save the control mode of Via Color TFT-LCD, disclose the electricity saving method of a kind of computer image system for No. 578046 as the TW patent announcement, the electricity saving method of this computer image system comprises the following steps: to obtain the starting time that comprises a picture first period to the concluding time; The default image time of more above-mentioned first period and a computer image system; And when be shorter than above-mentioned default image time above-mentioned first period, aforementioned calculation machine image system was at each picture anergy when finish to finish to above-mentioned default image time above-mentioned first period.
The electricity saving method of aforementioned calculation machine image system needs behind computer image system anergy, wait for that the general time carries out the operation that just continued of hot machine, so cause the inconvenience in the use, and if under long-time user mode, then any disabled state can not occur, so just can't reach the purpose of saving electric power.
In addition, also occurred the pre-viewing system of a kind of GTG on the market, as No. the 92124561st, TW patented claim, disclosed a kind of pre-viewing system of digital camera, this system comprises: a camera produces one first image signal; One image signal treating apparatus will must have one second image signal of gray-level characteristic after this first image signal correction; And a display device, provide photography pre-visual function according to this second image signal.
Yet the pre-viewing system of above-mentioned GTG can't satisfy the needed visual experience to common people, and rich color and complete photographic picture also can not be provided, and therefore for most user, would rather buy more battery so that complete photographic picture to be provided.
Be relevant to the mode that digital camera adopts imperfect display frame and manual power-saving control in the known technology, but possibly can't provide comprehensively and total solution for the operation of conservation of power and convenience now.Therefore, provide a kind of perfect display mode and have electricity-saving function and become current active demand.
