Abstract

La presente invención detecta y distingue una anormalidad de apariencia dañina a partir de una mancha de aceite, una raya de recocido o similar, como una anormalidad de apariencia inocua en una lámina de acero como un objeto de inspección en el cual la laminación u otro tratamiento superficial no es realizado sobre una superficie de la misma. La presente invención es proporcionada con una unidad de iluminación 3 para iluminar una región 8 de objeto de formación de imagen, una primera unidad de formación de imagen por luz de reflexión difusa 4 para capturar una imagen de luz de reflexión difusa en una dirección en la cual el ángulo de la misma con una dirección de reflexión regular es un primer ángulo ?, una segunda unidad de formación de imagen por luz de reflexión difusa 5 para capturar una imagen de la luz de reflexión difusa en una dirección en la cual el ángulo de la misma con la dirección de reflexión regular es un segundo ángulo d (donde d > ?), y una unidad de procesamiento de señal de imagen 6 para procesar una primera señal de imagen de reflexión difusa T1 obtenida por la captura de la imagen por la primera unidad de formación de imagen por luz de reflexión difusa 4 y una segunda señal de imagen de reflexión difusa T2 obtenida por la captura de la imagen por la segunda unidad de formación de imagen por luz de reflexión difusa 5. La unidad de procesamiento de señal de imagen 6 detecta como una región de defecto superficial, una región que tiene una luminancia menor que un primer valor de umbral predeterminado en la primera señal de imagen de reflexión difusa T1, la segunda señal de imagen de reflexión difusa T2 que tiene una luminancia mayor que un segundo valor de umbral predeterminado para la región.
