Abstract
A method provided by this disclosure for adjusting white balance data may comprise: reading a first white balance data of an image of a target signal source; performing a first adjustment operation such that the first white balance data complies with a predetermined target value and a second white balance data is generated; sending the second white balance data to signal source channels except the target signal source; and performing a second adjustment operation, wherein the second adjustment operation is a second adjustment performed on a third white balance data of the signal source channels according to the second white balance data.
Claims18
A method for adjusting white balance data, comprising:
- reading only a first white balance data of an image of a certain target signal source, without reading white balance data of other signal sources other than the certain target signal source;
- performing a first adjustment operation such that the first white balance data complies with a predetermined target value and a second white balance data is generated;
- sending the second white balance data to signal source channels of the other signal sources except the certain target signal source;
- and
- performing a second adjustment operation, wherein the second adjustment operation is a second adjustment performed on a third white balance data of the signal source channels of the other signal sources according to the second white balance data,
- wherein the performing of a first adjustment operation comprises:
- comparing the predetermined target value with the first white balance data to acquire a comparison result;
- and
- when the comparison result indicates that the first white balance data does not comply with the predetermined target value, adjusting source data in the first white balance data such that the target data in the first white balance data falls within a range of the predetermined target value.

An apparatus for adjusting white balance data, comprising:
- a storage device configured to store computer programs;
- a processor configured to be coupled with the storage device,
- wherein the processor, when calling and executing the computer programs stored in the storage device, is configured to achieve the following units:
- a reading module configured to read only a first white balance data of an image of a certain target signal source, without reading white balance data of other signal sources other than the certain target signal source;
- a first performing module configured to perform a first adjustment operation such that the first white balance data complies with a predetermined target value and a second white balance data is generated;
- a sending module configured to send the second white balance data to signal source channels of the other signal sources except the certain target signal source;
- and
- a second performing module configured to perform a second adjustment operation, wherein the second adjustment operation is a second adjustment performed on a third white balance data of the signal source channels of the other signal sources according to the second white balance data,
- wherein the first performing module comprises:
- a first comparing module configured to compare the predetermined target value with the first white balance data to acquire a comparison result;
- and
- a first adjusting module configured to, when the comparison result indicates that the first white balance data does not comply with the predetermined target value, adjust source data in the first white balance data such that the target data in the first white balance data falls within a range of the predetermined target value.

- send the second white balance data to signal source channels of the other signal sources except the certain target signal source;
- and perform a second adjustment operation, wherein the second adjustment operation is a second adjustment performed on a third white balance data of the signal source channels of the other signal sources according to the second white balance data,
- wherein the apparatus for adjusting white balance data comprises:
- a first comparing module, configured to compare the predetermined target value with the first white balance data to acquire a comparison result;
- and
- a first adjusting module, configured to, when the comparison result indicates that the first white balance data does not comply with the predetermined target value, adjust source data in the first white balance data such that the target data in the first white balance data falls within a range of the predetermined target value.
