Problems solved by technology

[0003] In addition, electronic equipment including a display device may have display unevenness caused by manufacturing variation in the stage before the user starts using it, that is, in the manufacturing stage of the electronic equipment before shipment (hereinafter referred to as initial display unevenness).
The initial display unevenness is caused by the unevenness of the characteristics of each pixel included in the display device

no. 2 approach

[0085] Next, refer to Figure 8A ~ Figure 9B The flowchart shown in the figure explains the image control method of the second embodiment of the present invention using the correction image generation system described above. Here, in the image control method shown in the flowchart, a computer including a CPU in the corrected image generation system executes the following operations: reads the image control program stored in the ROM, uses the RAM as a work area, and exerts the following operations: Figure 4 The function of each part of the corrected image generation system shown in et al.

[0086] First, for example, when the user touches a predetermined display displayed on the display unit 20, the CPU of the control unit 40 starts the image control program, and executes the image control program so that each part of the corrected image generation system 10 performs the following steps. That is, the user can visually recognize the display unevenness U1 to U4 generated in the...

no. 3 approach

[0134] In the image control method according to the third embodiment of the present invention, in S30 of the second embodiment, when the dark portion of the display unevenness after the start of use of the electronic device matches the dark portion of the initial display unevenness, the correction value The generation unit 415 generates correction data by maintaining a consistent grayscale value of the coordinates of the dark portion of the display unevenness and adjusting the grayscale values ​​of other coordinates of the display unevenness. Regarding this, based on Figure 9A The flow chart shown here describes this embodiment. In addition, since the present embodiment differs from the second embodiment only in the step of generating correction data ( S30 ), only the differences will be described below.

[0135] First, after S20, the display unevenness determination unit 413 determines whether the display unevenness is a bright portion or a dark portion of the coordinates w...

no. 4 approach

[0143] In the image control method according to the fourth embodiment of the present invention, in S30 of the second embodiment, the correction value generator 415 adjusts the gradation value of the bright portion of the display unevenness in the captured image data, and maintains the display unevenness. The gray value of the dark part of , thus generating correction data. Regarding this, based on Figure 9B The flow chart shown here describes this embodiment. In addition, this embodiment differs from the second embodiment in the step of generating correction data ( S30 ), similarly to the third embodiment, so only the differences will be described below.

[0144] First, after S20, the display unevenness determining unit 413 judges that the display unevenness is a bright part for the coordinates where the display unevenness occurs based on the gradation difference data input from the gradation difference generating unit 412, as in the third embodiment. Still Anbu (S301).

Abstract

This correction image generation system comprises: an electronic apparatus body including a display unit, a storage unit which stores reference image data, a correction data generation unit which generates correction data by using a reference image displayed on the display unit, and an image data correction unit which corrects image data by using the correction data; and an image-capturing unit which acquires captured image data by capturing the reference image. The display unit displays the reference image on the basis of amended reference image data obtained by correcting reference image data with initial correction data generated at the manufacturing stage of an electronic apparatus. The correction data generation unit generates correction data on the basis of a comparison result between the captured image data or captured image data-based data, and the reference image data or reference image data-based data.

Description

technical field [0001] The present invention relates to a correction image generation system, an image control method, an image control program, and a recording medium. Background technique [0002] Display devices such as organic electroluminescent (hereinafter referred to as "organic EL") display devices and liquid crystal display devices are used in various applications such as television receivers and display sections of portable devices. In these display devices, a desired color (brightness) to be displayed based on an input signal and an actually displayed color (brightness) may differ due to the influence of input-output characteristics of the display device. Therefore, correction such as so-called gamma correction is performed according to the characteristics of the display device. [0003] In addition, electronic equipment including a display device may have display unevenness (hereinafter referred to as initial display unevenness) caused by manufacturing variation...
