Abstract
An image processing method includes receiving an image including a plurality of pixels; compensating a color temperature of at least one pixel included in the image according to a color of the at least one pixel; and outputting the image according to a result of the compensating, wherein the compensating includes: measuring a color temperature of the image; and applying a color temperature compensation value to the at least one pixel based on the measured color temperature and the color of the at least one pixel.
Claims19
An image processing method comprising:
- receiving an image comprising a plurality of pixels;
- compensating a color temperature of at least one pixel of the image according to a color of the at least one pixel;
- and
- outputting the image according to a result of the compensating,
- wherein the compensating comprises:
- measuring a color temperature of the at least one pixel;
- and
- applying a color temperature compensation value to the at least one pixel based on the measured color temperature and the color of the at least one pixel, and
- wherein the applying comprises:
- analyzing the color of the at least one pixel;
- determining whether the color of the at least one pixel exists in a look up table;
- and
- in response to determining that the color of the at least one pixel exists in the look up table, determining the color temperature compensation value corresponding to the color and the measured color temperature of the at least one pixel by using the look up table and applying the determined color temperature compensation value to the at least one pixel.
An electronic system comprising:
- a camera configured to capture an image comprising a plurality of pixels;
- a color temperature measurer configured to measure a color temperature of at least one pixel of the image;
- a look up table configured to store a color temperature compensation value for adjusting the color temperature, according to the color temperature and a color of the at least one pixel;
- and
- a white balance adjuster configured to read out the color temperature compensation value corresponding to the measured color temperature and the color of the at least one pixel from the look up table to compensate the color temperature of the at least one pixel of the image.
An image signal processing apparatus comprising:
- a preprocessing module configured to perform a preprocessing operation on an image;
- a color temperature measurer configured to measure a color temperature of at least one pixel of the image;
- a look up table configured to store a color temperature compensation value for adjusting the color temperature, according to the color temperature and a color of the at least one pixel;
- a white balance adjuster configured to read out the color temperature compensation value corresponding to the measured color temperature and the color of the at least one pixel from the look up table to compensate the color temperature of the at least one pixel of the image;
- and
- a post-processing module configured to perform a post-processing operation on the image of which the color temperature of the at least one pixel is compensated.
