Abstract

PURPOSE:To inform of distinct and correct display contents regardless of a degree of brightness in the circumference by changing display luminance in accordance with the degree of brightness in the circumference. CONSTITUTION:It is constituted of a signal input part 1, a light quantity detection part 2, a luminance generation part 3, a luminance adjustment part 4 and a display part 5. The display input part 1 is a part to detect a signal input state from outside, and when there is a signal input, it gives an instruction to the luminance generation part 3 to generate luminance at a specified level. The light quantity detection part 2 detects a light quantity level in the circumference and sends a detection signal to the luminance adjustment part 4, and the luminance adjustment part 4 adjusts a luminance signal of the luminance generation part 3 in accordance with this detection signal and outputs the luminance signal to the display part 5. Consequently, it is possible to carry out distinct display regardless of a degree of brightness in the circumference.

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.
