A system for detecting the vision and luminance of a back light unit is provided to combine a vision inspection for detecting defects in the back light unit and an operation of measuring the luminance of the back light unit and automate the combined operation to simplify the manufacturing process of the back light unit. A system for detecting the vision and luminance of a back light unit(4) includes a main body(2) having an inspection chamber, a lighting jig(5), a vertical image acquisition camera, a viewing angle acquisition camera, an image processor, an output unit, and an upper luminance measurement unit(10). The lighting jig is reciprocated along a guide rail(3) of the main body. The back light unit is located on the lighting jig. The vertical image acquisition camera vertically line-scans the back light unit passing through the inspection chamber. The viewing angle acquisition camera line-scans the back light unit passing through the inspection chamber at a predetermined angle. The image processor processes the image captured by the cameras and detects a defect in the back light unit. The output unit displays the defect detected by the image processor. The upper luminance measurement unit measures the upper luminance of the back light unit passing through the inspection chamber along the guide rail.
