Abstract
Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、表示輝度制御方式に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a display brightness control method.
従来、監視装置の表示は一定の輝度であり、周囲の明る
さの程度とは無関係となっていた。Conventionally, the display of a monitoring device has a constant brightness and is independent of the level of surrounding brightness.
上述した従来の技術は、表示が一定の輝度であり、周囲
の光量が太いときは表示が見えにくいし、周囲が暗いと
きは、表示が明るすぎるという欠点がある。The conventional technology described above has the disadvantage that the display has a constant brightness, and the display is difficult to see when the amount of surrounding light is large, and the display is too bright when the surroundings are dark.
本発明の表示輝度制御方式は、信号の入力があると一定
レベルの輝度を発生させる輝度発生部と、周囲の光量を
検出する光量検出部と、この光量検出部の出力に応じて
表示部の輝度を調節する輝度調節部とを含んで構成され
る。The display brightness control method of the present invention includes a brightness generation section that generates a certain level of brightness when a signal is input, a light amount detection section that detects the amount of surrounding light, and a display brightness control method that adjusts the display according to the output of the light amount detection section. and a brightness adjustment section that adjusts brightness.
本発明について図面を参照して説明する。 The present invention will be explained with reference to the drawings.
第1図は本発明の一実施例を示すブロック図である。FIG. 1 is a block diagram showing one embodiment of the present invention.
第1図に示す表示輝度制御方式は、信号入力部1と、光
量検出部2と、輝度発生部3と、輝度調節部4と、表示
部5から構成される。The display brightness control system shown in FIG. 1 includes a signal input section 1, a light amount detection section 2, a brightness generation section 3, a brightness adjustment section 4, and a display section 5.
信号入力部1は外部からの信号入力状態を検出する部分
で、信号入力があると輝度発生部3に対して一定レベル
の輝度を発生するよう指示を出す。The signal input section 1 is a section that detects the state of signal input from the outside, and when a signal is input, it issues an instruction to the brightness generation section 3 to generate a certain level of brightness.
光量検出部は周囲の光量レベルを検出して、検出信号を
輝度調節部4に対して送る。輝度調節部4は、この検出
信号に応じて輝度発生部の輝度信号を調節し、表示部5
に対して輝度信号を出力する。The light amount detection section detects the surrounding light amount level and sends a detection signal to the brightness adjustment section 4. The brightness adjustment section 4 adjusts the brightness signal of the brightness generation section according to this detection signal, and adjusts the brightness signal of the brightness generation section to display the display section 5.
Outputs a brightness signal for.
以上説明したように本発明は、表示輝度を周囲の明るさ
の程度に応じて自動的に変化させることにより、使用者
に対して周囲の明るさの程度に関係なく明瞭かつ正確な
表示内容を知らせることが可能になるという効果がある
。As explained above, the present invention automatically changes display brightness according to the level of surrounding brightness, thereby providing the user with clear and accurate display content regardless of the level of surrounding brightness. This has the effect of making it possible to inform.
