Claim Text:
1. An image processing apparatus connected to a display apparatus and an imaging apparatus configured to change an imaging setting, the imaging processing apparatus comprising: a processor configured to execute program codes for controlling the image processing apparatus to function as: an input unit configured to take in an input image of an object in a production line acquired by the imaging apparatus; a calculation unit configured to calculate an effective luminance value which is according to a number of pixels having a luminance within a preset effective luminance range included in the input image; and an output unit configured to output a history of the temporal change of the effective luminance value, the history includes the effective luminance value calculated latest and the effective luminance value calculated before the effective luminance value calculated latest, wherein the output unit is configured to display a graph of the effective luminance value on a time axis as the history of the temporal change of the effective luminance value, wherein the effective luminance value is a percentage of the number of the pixels having the luminance within the preset effective luminance range defined by a lower limit value and an upper limit value to the total number of pixels included in the input image, wherein the calculation unit is configured to calculate a percentage of the number of pixels having a luminance which is higher or lower than the higher limit value or the lower limit value, respectively, to the total number of pixels included in the input image as a first ineffective luminance value or a second ineffective luminance value, respectively, and the output unit is configured to display a history of a temporal change of the first ineffective luminance value or the second ineffective luminance value, respectively.
