LIGHT SOURCE INFORMATION COLLECTNG DEVICE AND IMAGE PICKUP DEVICE USING THE SAME

摘要

PURPOSE: To obtain the light source information collection device in which information of a light source lighting an object is grasped with high accuracy and white balance of the image pickup device is easily and accurately corrected and to obtain the image pickup device using it. CONSTITUTION: A color correction processing section of the image pickup device obtains a spectral distribution of a light source lighting an object based on both spectral distribution characteristics of the object obtained by a spectral measurement means 6 when a flash 5 is flashed and not flashed and a spectral distribution characteristic of a flash light stored in a memory. Then a WB coefficient generating means 8 generates a white balance coefficient with respect to each color based on the spectral sensitivity distribution of each color of an image pickup element 2 and the spectral distribution of the light source lighting the object.
