Information processing device, its control method, and program

Abstract

In an information processing device that has both barcode display and screen color inversion functions, if the barcode is also displayed with color inversion, the barcode reader will not be able to correctly recognize the barcode. [Solution] The system sets either a first mode that outputs an image with standard color information or a second mode that outputs an image with the color information inverted, and determines whether the image contains a code image that indicates a code. If the second mode is set and it is determined that the image contains a code image, the system outputs an image in which everything except the code image of that image is inverted.

Claims

1. An information processing device, A setting means for setting either a first mode that outputs an image with standard color information, or a second mode that outputs an image with inverted color information, A determination means for determining whether an image contains a code image that shows a code, When the setting means sets the second mode and the determination means determines that the code image is included, the control means controls the output of an image in which the parts of the image other than the code image are inverted. An information processing device characterized by having the following features.

2. The information processing apparatus according to claim 1, wherein in the second mode, the control means performs a color inversion process for each component constituting the image.

3. The information processing apparatus according to claim 1, characterized in that, in the second mode, the control means performs a color inversion process on the components constituting the image all at once.

4. The information processing apparatus according to claim 2 or 3, characterized in that the color inversion process is a process of converting each value representing the RGB of each pixel of the component to a bit-inverted value.

5. In the second mode, the system further includes an instruction means for indicating whether or not to output the code image with its colors inverted, The information processing apparatus according to any one of claims 1 to 4, characterized in that the control means outputs an image in which everything except the code image of the image is inverted when the instruction means instructs the code image to be output with its colors inverted.

6. The information processing apparatus according to any one of claims 1 to 5, characterized in that the code image includes a barcode or a QR code.

7. It further has a means of display, The information processing apparatus according to any one of claims 1 to 6, characterized in that the control means outputs the image to the display means for display.

8. It further has printing means, The information processing apparatus according to any one of claims 1 to 6, characterized in that the control means outputs the image to the printing means and prints it.

9. A control method for controlling an information processing device, A setting process to select either a first mode that outputs the image with standard color information, or a second mode that outputs the image with the color information inverted, A determination step to determine whether or not an image contains a code image that shows a code, If the second mode is set in the setting step and the determination step determines that the code image is included, a control step is performed to control the output of an image in which the parts of the image other than the code image are inverted. A control method for an information processing device, characterized by having the following features.

10. A program for causing a computer to function as one of the means of an information processing apparatus according to any one of claims 1 to 8.
