    摘要: Provided is an LED driving device which can stably reduce brightness of an LED. The LED driving device provided with: a driving voltage switching means (Q1008) for switching between a first driving voltage and a second driving voltage in accordance with a timing signal; and feedback circuits (Q1001 to Q1005) to which any one of the first and second driving voltages is applied and which thereby determine a current flowing through an LED. The feedback circuits are provided with a resistor switching means (Q2001) for switching, in accordance with the timing signal, between resistors (R1001, R1002, and R2001) that determine the current flowing through the LED.

    摘要: When correcting (converting) a video signal from an imaging system and a recording system to be faithfully reproduced on a display device, this image processor corrects (converts) the video signal to a video equal to that reproduced by an ideal display device intended by an imaging person. Therefore, the image processor is capable of reproducing and displaying the video which is faithful to the color intended by the imaging person and which contains no distortion in luminance to a viewer who is an end user. The image processor has a means which is connected directly or indirectly with the display device to transmit video information, a means which obtains or selecting reproduction property information of the connected display device, a means which converts the video information to reproduce a video in a faithful color on the display device with the use of the obtained reproduction property information, and a means which controls a transmission part to output the converted video information. Moreover, the image processor has a means for performing similar processing for reproducing the video containing no distortion in luminance.
