Color information detecting device |
摘要 |
In a colorimetric sensor having a plurality of color sensors each of which is composed of a photo-electric conversion element for converting light into an electrical signal and a color filter added to the photo-electric conversion element for transmitting light of a specific wave length region, each of the color sensors is composed of a plurality of polygonally split pieces radially extending and spreading from a central part of the colorimetric sensor. A color sensor of a relatively low sensitivity has a greater number of split pieces than others. Among these color sensors, a color sensor having the lowest sensitivity has its split pieces either partially or totally disposed in a position covering two sides of an angular corner part of the colorimetric sensor.
