COLOR IMAGE DATA GENERATION DEVICE AND VISUAL INSPECTION DEVICE WITH THE SAME

PROBLEM TO BE SOLVED: To provide a color image data generation device for generating color image data by imaging a conveyed target object from a plurality of directions with a three-line system camera.SOLUTION: If each of the parallel intervals between line sensors 111, 112, and 113 is P, the resolution of a target object W conveyed along a conveyance surface and imaged from an upper direction is a, and the resolution of the target object W imaged from a side direction is b, an angle between the side direction L and the direction of conveyance K within a conveyance plane satisfies the relations P=s×a and P=t×b, and the side direction L is set to an angle of =sin(s/t). In the image data of each of the RGB components, an upper image included in the n-th, (n+s)-th, and (n+2 s)-th image data in the upper direction and a side image included in m-th, (m+t)-th, and (m+2 t)-th image data in the side direction are combined respectively to generate color image data (s, t, n, m are integers of 1 or greater).
