Problems solved by technology

However, this adjustment is performed on the output image and thus is not a technique for optimizing the input image fed by the image scanner
Therefore, in the case where facial features are already difficult to distinguish from the input image when the input image is input by the image scanner, it is difficult to restore underexposed parts and overexposed parts even if the brightness, shadow level, and density of the output image are adjusted

Embodiment Construction

[0019] An image processing device according to an embodiment will be described with reference to the drawings.

[0020] [Structure of Image Processing Device]

[0021] Such as Figure 1A As shown, a multifunction peripheral (MFP) 1 (an example of an image processing device in this application) includes a central processing unit (CPU) 3 (an example of a processor in this application), a random access memory (RAM) 5 (example of memory in this application) and read only memory (ROM) 7. The MFP 1 also includes a reading unit 11, an imaging unit 12 (an example of a reader in this application), an auxiliary memory 13, an input unit 14 (an example of an operation interface in this application), a display unit 15 (an example of an operation interface in this application). example of the display in the application) and the communication unit 16. These components are connected to the CPU 3 via the interface unit 18 .

[0022] The CPU 3 executes various processes according to the prog...

Abstract

An image processing device is configured to perform: reading an image of an original while a light emitting portion emits light with a first lighting color to acquire first image data representing the image; storing the first image data in a memory; executing a recognition process for recognizing an ID photograph in the image represented by the first image data; in response to determining that the ID photograph is recognized, outputting the image represented by the first image data; in response to determining that the ID photograph is not recognized, switching a lighting color of the light emitting portion from the first lighting color to a second lighting color different from the first lighting color; and reading the image of the original while the light emitting portion emits light with the second lighting color to acquire second image data representing the image.

Description

technical field [0001] The present invention relates to an image processing device. Background technique [0002] An image forming apparatus having a function of outputting images of the front side and the back side of a driver's license onto a sheet is known. When such an image forming apparatus is used to copy a driver's license, images of both sides of the driver's license are read by an image scanner, and recorded (or printed) on a recording medium. [0003] The front side of the driver's license as described above has an area where a photo of the driver's face is placed (hereinafter simply referred to as a face photo area). Not only a driver's license but also various cards such as various identification (ID) cards and business cards have an ID photo area such as a facial photo area. When the images of these cards are read by an image scanner as described above, it can be difficult to distinguish facial features from the output image due to the tone, shade level, or d...
