Claim of US Patent No. 10,002,572
1. A liquid crystal monitor device used for a display system including a plurality of liquid crystal monitor devices which modulate light of a backlight using a liquid crystal panel and display an image, the liquid crystal monitor devices comprising a parent device, the liquid crystal monitor device comprising:a liquid crystal monitor;
a backlight which outputs visible light to the liquid crystal monitor;
an adjustment switch configured to receive an input of a first backlight-setting value of an own device which is an adjustment value adjusted manually for luminance of the backlight;
a reception unit configured to receive a backlight-setting value of the parent device from the parent device, the backlight-setting value of the parent device comprising an adjustment value adjusted manually for luminance of a backlight of the parent device;
a control unit configured to adjust a luminance of the backlight of the own device; and
a storage configured to store a relationship between backlight-setting values of the own device and the parent device,
wherein the control unit is configured to:
adjust, when the adjustment switch receives the input of the first backlight-setting value of the own device, the luminance of the backlight on the basis of the first backlight-setting value of the own device and update the stored relationship to a first correction value on the basis of at least the first backlight-setting value of the own device;
calculate, when the reception unit further receives the backlight-setting value of the parent device, a second backlight-setting value of the own device corresponding to the received backlight-setting value of the parent device on the basis of the stored relationship and adjust the luminance of the backlight on the basis of the calculated second backlight-setting value of the own device; and
adjust, when the adjustment switch receives the input of a third backlight-setting value of the own device, the luminance of the backlight on the basis of the third backlight-setting value of the own device and update the stored relationship to a second correction value on the basis of at least the third backlight-setting value of the own device.
a backlight which outputs visible light to the liquid crystal monitor;
an adjustment switch configured to receive an input of a first backlight-setting value of an own device which is an adjustment value adjusted manually for luminance of the backlight;
a reception unit configured to receive a backlight-setting value of the parent device from the parent device, the backlight-setting value of the parent device comprising an adjustment value adjusted manually for luminance of a backlight of the parent device;
a control unit configured to adjust a luminance of the backlight of the own device; and
a storage configured to store a relationship between backlight-setting values of the own device and the parent device,
wherein the control unit is configured to:
adjust, when the adjustment switch receives the input of the first backlight-setting value of the own device, the luminance of the backlight on the basis of the first backlight-setting value of the own device and update the stored relationship to a first correction value on the basis of at least the first backlight-setting value of the own device;
calculate, when the reception unit further receives the backlight-setting value of the parent device, a second backlight-setting value of the own device corresponding to the received backlight-setting value of the parent device on the basis of the stored relationship and adjust the luminance of the backlight on the basis of the calculated second backlight-setting value of the own device; and
adjust, when the adjustment switch receives the input of a third backlight-setting value of the own device, the luminance of the backlight on the basis of the third backlight-setting value of the own device and update the stored relationship to a second correction value on the basis of at least the third backlight-setting value of the own device.
