causing a display unit to display a plurality of patch displays according to a plurality of expected colors of the plurality of patches being acquired, and a procedure of sequentially measuring, by a colorimetric apparatus, the plurality of patches formed on the chart; sequentially acquiring measured values measured by the colorimetric apparatus; and sequentially displaying objects indicating measured colors, based on the measured value for each patch being acquired in a manner superimposed on a part of the patch display according to a corresponding expected color such that a display portions of the expected colors are connected between at least one pair of adjacent patch displays even after the objects are displayed. ## Claims ### Claim 1 An information processing apparatus comprising: at least one memory device that stores a set of instructions; and at least one processor that executes the set of instructions to: generate a first chart including a first reference patch and a second reference patch; generate a first read result patch and a second read result patch based on a read result obtained by reading the first reference patch and the second reference patch; and generate a second chart including the first reference patch and the second reference patch, and the first read result patch and the second read result patch, wherein, in the first chart, the first reference patch and the second reference patch are arranged adjacent to each other, and wherein, in the second chart, the first read result patch is arranged adjacent to the first reference patch, the second read result patch is arranged adjacent to the second reference patch, and the first reference patch and the second reference patch are arranged adjacent to each other. ### Claim 2 (depends on 1) The information processing apparatus according to claim 1, wherein, in the second chart, the first read result patch and the second read result patch are different in size or shape from the first reference patch and the second reference patch. ### Claim 3 (depends on 1) The information processing apparatus according to claim 1, wherein, in the second chart, the first read result patch and the second read result patch are not arranged adjacent to each other. ### Claim 4 (depends on 1) The information processing apparatus according to claim 1, wherein in the second chart, the first read result patch includes one boundary with the first reference patch, or the second read result patch includes one boundary with the second reference patch. ### Claim 5 (depends on 1) The information processing apparatus according to claim 1, wherein, in the first chart and the second chart, a number of colors at an upper side and a left side of the first reference patch and the second reference patch is unchanged. ### Claim 6 (depends on 1) The information processing apparatus according to claim 1, wherein, in the second chart, the first reference patch and the first read result patch share at least one point, and the second reference patch and the second read result patch share at least one point. ### Claim 7 (depends on 1) The information processing apparatus according to claim 1, wherein the at least one processor further executes the set of instructions in the memory device to: perform measurement of at least one of each predetermined unit reference patch object, each row object on which a reference patch is arranged, or each page object having the first reference patch and the second reference patch, and display a reference patch display not measured, which is subsequent to reference patch of an object to be measured, with changing at least one parameter of display relating to the reference patch. ### Claim 8 (depends on 7) The information processing apparatus according to claim 7, wherein the parameter relating to the display includes at least one of brightness and saturation. ### Claim 9 (depends on 1) The information processing apparatus according to claim 1, wherein the first read result patch or the second read result patch is displayed with changing at least one of patch size or aspect ratio of the first reference patch or the second reference patch formed in the chart. ### Claim 10 (depends on 1) The information processing apparatus according to claim 1, wherein the first read result patch or the second read result patch is changed in accordance with a display size of the first reference patch or the second reference patch. ### Claim 11 (depends on 1) The information processing apparatus according to claim 1, wherein the first read result patch or the second read result patch is displayed in a manner satisfying at least one of: being different in size or shape from the first reference patch or the second reference patch, the first read result patch or the second read result patch being not connected, a boundary with the first read result patch and the second read result patch being one, and a number of colors at an upper side and a left side of the first reference patch and the second reference being unchanged in the first chart or the second chart. ### Claim 12 (depends on 1) The information processing apparatus according to claim 1, wherein the at least one processor further executes the set of instructions in the memory device to: generate a reading procedure for reading the first chart; and display the generated procedure on a display unit. ### Claim 13 A control method for an information processing apparatus, comprising: generating a first chart including a first reference patch and a second reference patch; generating a first read result patch and a second read result patch based on a read result obtained by reading the first reference patch and the second reference patch; and generating a second chart including the first reference patch and the second reference patch, and the first read result patch and the second read result patch, wherein, in the first chart, the first reference patch and the second reference patch are arranged adjacent to each other, and wherein, in the second chart, the first read result patch is arranged adjacent to the first reference patch, the second read result patch is arranged adjacent to the second reference patch, and the first reference patch and the second reference patch are arranged adjacent to each other. ### Claim 14 A non-transitory computer-readable storage medium storing a computing program for causing a computer to execute each process of a control method of an information processing apparatus, the control method comprising: generating a first chart including a first reference patch and a second reference patch; generating a first read result patch and a second read result patch based on a read result obtained by reading the first reference patch and the second reference patch; and generating a second chart including the first reference patch and the second reference patch, and the first read result patch and the second read result patch, wherein, in the first chart, the first reference patch and the second reference patch are arranged adjacent to each other, and wherein, in the second chart, the first read result patch is arranged adjacent to the first reference patch, the second read result patch is arranged adjacent to the second reference patch, and the first reference patch and the second reference patch are arranged adjacent to each other.
