The embodiments of the present invention will be described in detail below with reference to the drawings and embodiments, and the present invention can be fully understood and implemented according to the application of the technical means to solve the technical problems and achieve the technical effects.

In the following, the image capturing device detecting system on the electronic device according to the present invention is first described. Please refer to FIG. 1 and FIG. 2, and FIG. 1 shows the electronic device according to the present invention. A system block diagram of an image capture device detection system on the device; "FIG. 2" is a block diagram showing the architecture of the image capture device detection system on the electronic device of the present invention.

The test fixture 20 is disposed on the image capturing device 11 to provide a standard test environment for the image capturing device 11 . The test fixture 20 provides the image capturing device 11 standard. The test environment is to provide a black box effect and a uniform light source and a standard image 21 are provided in the test fixture 20. The uniform light source is provided in the test fixture 20, that is, the light source is evenly distributed around the test fixture 20 The internal source provides a uniform light source, and the standard image 21 is indicated by reference.

The standard image 21 includes at least one color region 211 and at least one code region. 212, and it is worth noting that the colors in the color area 211 are respectively the same or different colors. In the "3rd picture", the three color areas 211 and one two-dimensional barcode area 212 are used as illustrations, and This limits the scope of application of the invention.

After the above-mentioned architecture setting is completed, the image capturing module 31 can capture the detection image including the standard image 21 from the image capturing device 11. Then, the decoding module 32 can be based on the one-dimensional barcode decoding method or two. The trellis barcode decoding method decodes the barcode of the detected image to generate a decoding result. The one-dimensional barcode decoding method analyzes the width and interval of the one-dimensional barcode to decode according to the width and interval of the one-dimensional barcode to generate a decoding result. The bar code is decoded according to the positioning mark, the correction mark, the version information and the format information defined by the two-dimensional bar code to generate a decoding result, which is merely an example, and is not limited to the application scope of the present invention, the one-dimensional bar code. The decoding method or the two-dimensional barcode decoding method can refer to the prior art, and will not be described again herein. In the "3rd picture", the two-dimensional barcode region 212 is decoded according to the two-dimensional barcode decoding method to generate a decoding result.

This is for illustrative purposes only and is not intended to limit the scope of application of the invention.

Then, the comparison module 33 is configured to compare each pixel point in the detected image with at least one RGB value range to compare at least one color pixel range, and it is worth noting that each color pixel range is The range of rectangles.

For example, assume that the first RGB value range is "R value is 255 to 250", "G value is 20 to 0", and "B value is 20 to 0", and it is assumed that the first pixel is in the detected image. The RGB values of all the pixels in the range of (50, 50), the second pixel (150, 50), the third pixel (50, 100), and the fourth pixel (150, 100) are within the first RGB value range. The comparison module 33 can compare the first pixel (50, 50), the second pixel (150, 50), the third pixel (50, 100), and the fourth pixel (150, 100) to the first color. The pixel range is merely illustrative here and is not intended to limit the scope of application of the present invention.

It is assumed that the second RGB value range is "R value is 20 to 0", "G value is 255 to 250", and "B value is 20 to 0", and it is assumed that in the detected image at the fifth pixel point (50, 150), Range of sixth pixel point (100, 150), seventh pixel point (50, 180), and eighth pixel point (100, 180) The RGB values of all the pixels in the range are in the second RGB value range, and the comparison module 33 can compare the fifth pixel point (50, 150), the sixth pixel point (100, 150), the seventh pixel point (50, 180), and The range of the eighth pixel (100, 180) is the second color pixel range, which is merely illustrative here, and is not intended to limit the scope of application of the present invention.

The decoding module 32 performs barcode decoding on the detected image according to the one-dimensional barcode decoding method or the two-dimensional barcode decoding method to generate a decoding result, and when the decoding result decoded by the decoding module 32 is inconsistent with the preset decoding result. The judging module 34 can determine that the image capturing device 11 fails the detection.

For example, it is assumed that the decoding module 32 performs barcode decoding on the detected image to generate a decoding result of “decoding error”, and assumes that the preset decoding result is “1234”, at which time the decoding result is “decoding error” and pre- If the decoding result is "1234", the determination module 34 can determine that the image capturing device 11 fails the detection.

Each pixel in the detected image of the comparison module 33 is compared with at least one RGB value range to compare at least one color pixel range, and the color pixel range compared by the comparison module 33 When the length of the length does not match the preset length, the judging module 34 can determine that the image capturing device 11 fails to pass the measurement.

Assume that the preset length is "100". At this time, since the length of the second color pixel range is "50" and the preset length is "100", the determination module 34 can determine that the image capturing device 11 is not Can pass the test.

Each pixel in the detected image of the comparison module 33 is compared with at least one RGB value range to compare at least one color pixel range, and the color pixel range compared by the comparison module 33 When the width of the difference does not match the preset width, the determining module 34 can determine that the image capturing device 11 fails the detection.

For example, assume that the second color pixel range that is compared by the comparison module 33 is a fifth pixel point (50, 150), a sixth pixel point (100, 150), a seventh pixel point (50, 180), and an eighth pixel point (100, 180). Assume that the preset width is "50". At this time, since the width of the second color pixel range is "30" and the preset width is "50", the determination module 34 can determine that the image capturing device 11 is not Can pass the test.

On the other hand, when the decoding result decoded by the decoding module 32 is consistent with the preset decoding result, the length of the color pixel range compared by the comparison module 33 is consistent with the preset length, and compared with the comparison module 33. When the width of the selected color pixel range is consistent with the preset width, the determination module 34 can determine that the image capturing device 11 passes the detection.

For example, it is assumed that the decoding module 32 performs barcode decoding on the detected image to generate a decoding result of “1234”, and assumes that the preset decoding result is “1234”, and the decoding result is “1234” and the preset decoding result. The second color pixel range that is aligned with the comparison module 33 is the first pixel point (50, 50), the second pixel point (150, 50), the third pixel point (50, 100), and The fourth pixel point (150, 100), and assumes that the preset length is "100" and the preset width is "50", and the length of the second color pixel range is "100" and the preset length is "100" and the The width of the two color pixel ranges is “50” and the preset width is “50”, and the determination module 34 can determine that the image capturing device 11 passes the detection.
