[0051] The present invention will be described below with multiple embodiments. Please note that the "first", "second" and similar descriptions in the following description are only used to define different elements, parameters, data, signals or steps. They are not used to limit their order. For example, the first device and the second device can be different devices with the same structure.
[0052] Figure 1A FIG. 1 is a block diagram of an optical decoding device according to an embodiment of the present invention. Figure 1AAs shown, the optical decoding device 100 includes an image sensor 101, a processing circuit 103, and a decoding device 105. The image sensor 101 is used to sense a first sensing image Img_1 and a second sensing image Img_2. The processing circuit 103 is used to determine the relative movement between the optical decoding device 100 and the object according to the first sensing image Img_1. For example, in one embodiment, the optical decoding device 100 is applied to an optical mouse, and the object is a working surface where the optical decoding device 100 is located. For another example, in one embodiment, the optical decoding device 100 is applied to an optical touch device, and the object is a finger or a stylus on the optical decoding device 100. The decoding device 105 is used to decode the second sensing image Img_2 in a first mode to generate a decoding result, and not to decode the second sensing image Img_2 in a second mode. The decoding device 105 switches between the first mode and the second mode according to the relative movement.
[0053] In one embodiment, the first sensing image Img_1 and the second sensing image Img_2 are generated using the same parameters, that is, the first sensing image Img_1 and the second sensing image Img_2 are the same sensing image. In another embodiment, the first sensing image Img_1 and the second sensing image Img_2 are generated using different parameters. For example, the first sensing image Img_1 and the second sensing image Img_2 are generated by different brightness, different resolutions, or different numbers of pixel circuits of the image sensor 101.
[0054] Specifically, in one embodiment, the processing circuit 103 controls the optical decoding device 100 to switch between the third mode and the fourth mode according to the relative movement. The power consumption of the optical decoding device 100 in the fourth mode is lower than the power consumption of the optical decoding device 100 in the third mode. For example, the third mode is a normal mode and the fourth mode is a sleep mode. In this case, the processing circuit 103 generates the control signal CS according to which of the third mode and the fourth mode the optical decoding device 100 operates in, so as to control the decoding device 105 to enter the first mode or the second mode.
[0055] Figure 1B According to an embodiment of the present invention, Figure 1A Schematic diagram of the operation of the optical decoding device 100 in FIG. Figure 1B In the embodiment of the present invention, the optical decoding device 100 is applied to an optical mouse and includes a light source. In the normal mode, the optical mouse is in a moving state, the relative movement is greater than the moving threshold, and the light source has a high light emission frequency and high power consumption. If the relative movement is 0 or less than the moving threshold, the mode is switched to a sleep mode. In the sleep mode, the light source has a low light emission frequency, so the power consumption is low.
[0056] In addition to the above-mentioned optical mouse and touch device, the optical decoding device 100 can also be applied to other devices. Figure 2 To illustrate an embodiment of the present invention, the Figure 1A as well as Figure 1B Schematic diagram of an electronic cigarette lighter 200 of an optical decoding device 100 is shown. Figure 2 As shown, the electronic cigarette lighter 200 includes a heating device 201, a control circuit 203, and a heating body 205 forming a chamber 207. If the chamber 207 is empty (i.e., the optical decoding device 100 does not sense an object), the optical decoding device 100 does not sense the relative movement, and thus the decoding device 105 operates in the second mode (the fourth mode of the optical decoding device 100). In this state, the heating device 201 does not provide heat energy according to the code from the optical decoding device 100 (i.e., no heating is performed). In one embodiment, the heating device 201 is in a sleep mode in this state. In another embodiment, if the processing circuit 103 determines that the cigarette 209 is being removed from the chamber according to the relative movement, the decoding device 105 operates in the second mode.
[0057] If the processing circuit 103 determines that the cigarette 209 is inserted into the chamber 207 according to the relative movement, the decoding device 105 switches from the second mode to the first mode. In one embodiment, when the decoding device 105 operates in the first mode, the optical decoding device 100 operates in the third mode. In this state, the optical decoding device 100 decodes the code block 211 on the cigarette 209 to generate a decoding result (i.e., provide a code). In this state, the above-mentioned object is the surface of the cigarette 209. Then, the heating device 201 provides heat energy according to the decoding result. In one embodiment, the code block 211 includes a code representing the heating parameter of the heating device 201. Therefore, the heating device 201 can automatically heat the cigarette 209 according to the code included in the code block 211. The user does not need to manually set the electronic cigarette lighter 200. In another embodiment, the code block 211 represents at least one type of cigarette. In this embodiment, the heating device 201 can set the heating parameter corresponding to the cigarette type. In this case, different cigarette types can correspond to the same heating parameter or different heating parameters.
[0058] The control circuit 203 is used to control the operation of the electronic cigarette lighter 200. In one embodiment, the control circuit 203 is in a sleep mode when the decoding device 105 is in the second mode, and is in a normal mode when the decoding device 105 is in the first mode.
[0059] Figure 3A as well as Figure 3B FIG. 1 is a diagram showing a method of performing a multi-function circuit according to an embodiment of the present invention. Figure 1A Schematic diagram of a bar code decoded by the decoding device 105. Figure 3A and Figure 3B Four examples are included. Figure 3A and Figure 3B In the embodiment of , the second sensing image Img_2 includes an image of a barcode having at least one first code bar BR_1 and at least one second code bar BR_2, wherein the first code bar BR_1 and the second code bar BR_2 represent different code values. Figure 3A and Figure 3B In Examples 1, 2, 3, and 4 of FIG. 1 , the first code bar BR_1 is a black bar having a code value of 0. In addition, the second code bar BR_2 is a black bar having a code value of 1.
[0060] In Example 1, the barcode has a first spacing SP_1 between the first barcode BR_1 and the next barcode, and a second spacing SP_2 between the second barcode BR_2 and the next barcode. The sum of the first width WD_1 of the first barcode BR_1 and the first spacing SP_1 is the same as the sum of the second width WD_2 of the second barcode BR_2 and the second spacing SP_2. For example, in the right figure of Example 1, the barcode value is 0110, and the sum of the width of each barcode in the barcode 0110 and the corresponding spacing is W.
[0061] In Example 2, the barcode has a first spacing SP_1 between the first barcode BR_1 and the next barcode, and a second spacing SP_2 between the second barcode BR_2 and the next barcode. The first width WD_1 of the first barcode BR_1 and the second width WD_2 of the second barcode BR_2 are different. In addition, the width of the first spacing SP_1 and the second spacing SP_2 are the same. For example, in the right figure of Example 2, the code value of the barcode is 0110, and the width of each bar in the barcode 0110 is different, but the spacing is WD_S.
[0062] In Example 3, the barcode has a first spacing SP_1 between the first barcode BR_1 and the next barcode, and a second spacing SP_2 between the second barcode BR_2 and the next barcode. The first width WD_1 of the first barcode BR_1 and the second width WD_2 of the second barcode BR_2 are the same. In addition, the widths of the first spacing SP_1 and the second spacing SP_2 are different. For example, in the right figure of Example 3, the code value of the barcode is 0110. The width of each bar in the barcode 0110 is the same, but the widths of the corresponding spacings are different.
[0063] In Example 4, the barcode has a first spacing SP_1 between the first code bar BR_1 and the next code, and a second spacing SP_2 between the second code bar BR_2 and the next code. The first code bar BR_1 or the second code bar BR_2 includes a plurality of discontinuous subcode bars. As shown in Example 4, the first code bar BR_1 includes discontinuous subcode bars BR_11 and BR_12, and the second code bar BR_2 includes discontinuous subcode bars BR_21 and BR_22. The subcode bars are distributed along a direction perpendicular to the decoding direction of the barcode. For example, in the right figure of Example 4, the code value of the barcode is 0110, and each code bar of the barcode 0110 includes discontinuous subcode bars distributed in the D_1 direction, and the D_1 direction is perpendicular to the decoding direction D_2.
[0064] Figure 3A and Figure 3B The barcodes shown are not limited to Figure 1A The decoding device 105 shown is used for decoding. Figure 3A and Figure 3B The barcodes shown may be replaced by other codes.
[0065] Figure 4 is a method according to an embodiment of the present invention which can be Figure 1A The color code decoded by the decoding device 105 in . Figure 4 The embodiment disclosed herein includes a color code 400. Figure 4 The left figure in the middle represents the color code 400 that has not been encoded, that is, the color code 400 has no code value. The color code 400 includes a positioning area LR and a plurality of code areas CR_1...CR_5. Each of the code areas CR_1...CR_5 includes a first subcode area and a second subcode area. Specifically, the code areas CR_1...CR_5 include first subcode areas SR_11...SR_51 and second subcode areas SR_12...SR_52, respectively. Figure 4 Each of the code regions CR_1 ... CR_5 can represent one bit.
[0066] In one embodiment, code regions CR_1 ... CR_5 have different colors, and sub-code regions in the same code region have the same color. For example, code regions CR_1 ... CR_5 are pink, yellow, blue, red, and green, respectively. In this case, the first sub-code regions SR_11 ... SR_51 are pink, yellow, blue, red, and green, respectively, and the second sub-code regions SR_12 ... SR_52 are pink, yellow, blue, red, and green, respectively. Please note that the background of color code 400 includes blocks. However, the background of color code 400 may be empty.
[0067] The positioning area LR is used to locate the decoding direction of the color code 400. The "positioning" referred to here means to identify the existence of the color code 400. In one embodiment, the decoding direction of the color code 400 is from the positioning area LR to the code areas CR_1...CR_5. In one embodiment, the positions of the first sub-code area and the second sub-code area can be determined according to the position or shape of the positioning area LR, so that the decoding direction can be obtained.
[0068] In addition, in one embodiment, the positioning area LR and the code areas CR_1 ... CR_5 are distributed along the first side SD_1, and the first sub-code area and the second sub-code area in the single code area are distributed along the second side SD_2 perpendicular to the first side SD_1. For example, the first sub-code area SR_21 and the second sub-code area SR_22 in the code area CR_2 are along the second side SD_2. In one embodiment, the first side refers to the long side of the color mark 400, and the second side refers to the short side of the color mark 400, so the second side is shorter than the first side.
[0069] Figure 4 The right figure of FIG. 4 shows the encoded color code 400_1. That is, some sub-code areas are marked with specific colors to represent the code. Figure 4 As shown, the subcode regions SR_11, SR_22, SR_31, SR_41, and SR_52 are marked in black. On the contrary, the original colors of the subcode regions SR_12, SR_21, SR_32, SR_42, and SR_51 are retained. In one embodiment, if the left side of the subcode region is marked, the code value of the code region is 0, and if the right side of the subcode region is marked, the code value of the code region is 1.
[0070] The color of the positioning area LR and the color used to mark the subcode area can be the same, but can also be different. Therefore, the color code 400_1 can be expressed as:
[0071] A color code includes: a positioning area (e.g., positioning area LR) having a first color (e.g., black); code areas (e.g., code areas CR_1 ... CR_5), wherein each code area includes a first sub-code area and a second sub-code area. In each code area, at least one of the first sub-code area and the second sub-code area has a second color. In one embodiment, one of the first sub-code area and the second sub-code area has a second color (e.g., sub-code areas SR_11, SR_22, SR_31, SR_41, and SR_52 are black), and the other in the first sub-code area has a second color (e.g., sub-code areas SR_12, SR_21, SR_32, SR_42, and SR_51 are pink, yellow, blue, red, and green, respectively).
[0072] In addition, the code value of each code area is determined by which of its first sub-code area and second sub-code area has the second color. For example, if the sub-code area on the left is marked, the code value of the code area is 0. If the sub-code area on the right is marked, the code value of the code area is 1. The first color and the second color can be the same or different. In addition, the colors of the first sub-code area without the second color and the second sub-code area without the second color in different code areas are different. For example, sub-code areas SR_12, SR_21, SR_32, SR_42 and SR_51 are pink, yellow, blue, red and green, respectively. Figure 4 The color code shown can still be read correctly even when set on a curved surface.
[0073] exist Figure 5-Figure 8 In an embodiment of the present invention, an invisible code is provided. Figure 5 In the embodiment of the present invention, the code includes at least one positioning area for positioning the code area. The details of the positioning area will be described in more detail later. Code 501_1 is a more detailed code of code 501.
[0074] Furthermore, Figure 5 The code in includes a plurality of code regions, wherein each code region includes a subcode region representing a first code value, wherein the first code value of each code region is determined according to the position of at least one subcode region in the code region. For example, code 501 includes a code region CR_a having a subcode region SR_a, and code 503 includes a code region CR_b having a subcode region SR_b. Each code region represents one bit of the code. Figure 5 The decoding direction of the code in can be from the positioning area to the code area.
[0075] In one embodiment, if the subcode region of the first code region in the code region is located in the upper region of the first code region, the first code value of the first code region is the first value. For example, since the subcode region SR_a is located in the upper region of the code region CR_a, the code region CR_a has a code value of 0. In addition, if the subcode region of the second code region in the code region is located in the lower region of the second code region, the first code value of the second code region is the second value. For example, since the subcode region SR_b is located in the lower region of the code region CR_b, the code region CR_b has a code value of 1. This method can be called a "single positioning method". According to such a rule, the code regions CR_c, CR_d, and CR_e of code 501_1 have code values of 000, and the code regions CR_f, CR_g, and CR_h of code 501_1 have code values of 010. In this case, the positioning region can be set between the upper region and the lower region.
[0076] In another embodiment, a method named "difference positioning method" is used. In such an example, the first code value is determined by the positional relationship of the subcode regions of two adjacent code regions in the code region. In one embodiment, if the subcode region of the current code region and the subcode region of the next code region have the same position, the first code value of the current code region is 0. For example, since the positions of the subcode regions of code regions CR_c and CR_d are the same, the code value of code region CR_c is 0. On the contrary, if the positions of the subcode region of the current code region and the subcode region of the next code region are different, the first code value of the current code region is 1. For example, since the positions of the subcode regions of code regions CR_f and CR_g are different, the code value of code region CR_f is 1.
[0077] In one embodiment, the positioning area is used to represent a second code value, wherein the second code value is determined according to the shape or color of the positioning area. Figure 5 , codes 501 and 501_1 respectively include location regions LR_a having the same shape. Therefore, the second code values of codes 501 and 501_1 are 0. According to the same rule, codes 503 and 503_1 respectively include location regions LR_b having the same shape. Therefore, the second code values of codes 503 and 503_1 are 1. Code 503_1 is a more detailed code of code 503. In one embodiment, the second code value refers to the value of bit 0 of the code.
[0078] According to the above-described embodiment, even if the subcode areas have the same distribution, the codes may have different code values. Figure 6 In the embodiment of FIG. 6 , because the above-mentioned “single positioning method” is used, code 601 has a code value of 01100. However, because the above-mentioned “difference positioning method” is used, code 603 has a code value of 00100. Therefore, the subcode areas of codes 601 and 603 have the same distribution, but codes 601 and 603 have different code values.
[0079] exist Figure 5 and Figure 6 In the embodiment, only a single row of code area is provided in the code. The "single row" mentioned here may refer to an area formed by two parallel lines located at the top and bottom of the positioning area, but is not limited thereto. For example, Figure 7 The embodiments may represent Figure 5 and Figure 6 In the image of the code shown, a "single row" is a region formed by two parallel lines PL_1 and PL_2 located at the top and bottom of the code 700, respectively. A "single row" can also be defined by other methods. For example, a "single row" refers to a region formed by two parallel lines having a predetermined distance.
[0080] In another embodiment, multiple rows of code regions may be provided in the code. Figure 8In an embodiment, the code regions CR_a1, CR_a2, CR_a3 of the code 800 are located in the first row, and the code regions CR_b1, CR_b2, CR_b3 are located in the second row. In an embodiment, the code regions CR_b1, CR_b2, CR_b3 are located in the second row formed based on the positioning region CR_b. However, the code 800 may have only one positioning region instead of multiple positioning regions.
[0081] exist Figure 8 In the embodiment of Figure 5 and Figure 6 The image of the code depicted first locates the code according to the location area LR_a in the first row or the location area LR_b in the second row. Then the code areas CR_a1, CR_a2, CR_a3 in the first row and the code areas CR_b1, CR_b2, CR_b3 in the second row with the same order are combined into a single code area. Specifically, Figure 8 The code areas CR_a1, CR_a2, and CR_a3 in represent the code value 110. Figure 8 The code regions CR_b1, CR_b2, and CR_b3 in also represent the code value 110. However, during the decoding process of the code 800, only one set of code values 110 (i.e., the first code value mentioned above) is obtained. The code disclosed in the present invention may also include code regions located in more than two rows, such as Figure 8 shown.
[0082] In addition, Figure 8 In an embodiment, the code regions CR_a1, CR_a2, CR_a3, CR_b1, CR_b2, CR_b3 are distributed along a first direction D_a and a second direction D_b of the positioning region. The first direction D_a is opposite to the second direction D_b. In such an embodiment, during the decoding process of the code, the code is decoded along the first direction D_a and the second direction D_b.
[0083] As described above, code 800 includes a plurality of adjacent positioning regions, such as positioning regions LR_a and LR_b. In such an embodiment, the adjacent positioning regions form a pattern for positioning the code regions. Note that this can also be applied to the case of a single row of code regions, such as Figure 5 , Figure 6 and Figure 7 Examples, but not limited to Figure 8 The embodiment shown.
[0084] Figure 5-Figure 8 The area of the positioning area and the code area shown can be designed to be very small, so Figure 5-Figure 8 The code shown may be invisible. Figure 5-Figure 8The positioning area and the code area shown can also be printed in other invisible ways. For example, the positioning area and the code area can be printed by infrared painting (IR painting).
