摘要： The invention provides a range finder capable of carrying out three-dimensional measurement stably for a long period of time. A light pattern is projected on a subject by using a light source array unit in which a plurality of light sources, such as LEDs, are arranged. Even when each LED has a small light quantity, a sufficiently large quantity of light can be projected on the subject by the entire light source array unit, and hence, the three-dimensional measurement can be stably carried out. Also, a plurality of light patterns can be generated by electrically controlling a light emitting state of each LED of the light source array unit.

摘要： A method and an apparatus performs contrast processing so that the contrast of a video signal displayed on a low contrast display device is improved. The apparatus and method prevent the picture from becoming whitish and from having its apparent contrast reduced, even when external light is present. The apparatus comprises a brightness level converting part for converting the brightness level of a picture to a brightness level which can be displayed with a low contrast display device. The apparatus further includes a contrast improving part for improving the contrast by superimposing a waveform on the input signal to create an optical illusion of a brightness level. A brightness level compensating part is also provided for compensating the brightness value of the light and dark parts of the brightness varying portions in the video input signal so that the light parts get darker and the dark parts get lighter.
