Filed: 2019-11-15
Abstract: To provide an image forming apparatus that can accurately read a bar code displayed on a screen.SOLUTION: An image forming apparatus that can read an image from a document in a platen-set method reads multiple times a bar code displayed on a screen of a smartphone placed on a platen glass in a state where lighting on an object to be read is turned off, and creates a plurality of read images. The image forming apparatus adds up pixel values of pixels corresponding to each other in the plurality of read images to determine a total value. In the individual read images, since a difference in pixel value between a white part and a black part of the bar code is small, it is difficult to accurately distinguish between the white part and the black part under the influence of noise (a), but in an added image, since noise is equalized and the difference in pixel value between the white part and the black part is increased, the distinguishing accuracy is improved (b).SELECTED DRAWING: Figure 7
