Method and arrangement for improving image quality on a display of an imaging device
View Patent ↗In the method and arrangement, a value of at least one image parameter of a liveview scene that is displayed on an imaging device display is determined. Based on the determined image parameter value, compensation value for the image parameter is determined, and the value of the image parameter is changed in accordance with the compensation value.
1. A method of correcting a color hue setting of a display unit in an imaging device for improving image quality of the liveview scene displayed on a display unit of the imaging device, comprising the steps of:
determining a color hue setting of the imaging device;
measuring a color hue value of image data representing the liveview scene;
calculating a compensation value based on the measured color hue value;
providing the image data representing the liveview scene to the display unit; and
adjusting the color hue setting of the display unit in accordance with the calculated compensation value without having to adjust the image data being provided to the display unit.
2. The method of claim 1 , wherein said calculating step further includes:
using an auto-white balance algorithm to determine a plurality of new color hue values based on each measured hue color hue value,
storing the auto-white balance algorithm-determined color hue values in memory, associating a liquid crystal display (LCD) hue correction value with each stored auto-white balance algorithm-determined color hue value, the LCD hue correction value representing the compensation value,
comparing a subsequently measured color hue value to the stored auto-white balance algorithm-determined color hue values, and
selecting the LCD hue correction value of the auto-white balance algorithm-determined color hue value that is closest to the measured color hue value.
3. The method of claim 2 , wherein the adjusting step further includes applying the selected LCD hue correction value to the color hue setting to improve image quality of the liveview scene.
4. The method of claim 1 , wherein the step of calculating a compensation value is automatically performed.
5. The method of claim 4 , wherein the automatically performed step of calculating is performed by a component of the imaging device.
