Abstract

A shooting method comprising the steps of: defining at least two sub-regions on a shot picture; using the at least two sub-regions as color temperature reference regions to conduct white balance adjustment and shoot photographs; determining a color temperature reference region selected on a shot photograph; and calling out a photograph obtained by shooting after white balance adjustment according to the selected color temperature reference region from the shot photographs and displaying same, so that it is realized that photographs are shot first and then white balance adjustment is conducted thereon. Although photographs are shot first and then white balance adjustment is conducted thereon, in fact, many photographs have been obtained after independent white balance adjustment is conducted when the photographs are shot. Therefore, embodiments may accurately restore a previous white balance effect in a shooting environment after the color temperature reference regions are selected afterwards.

First claim

What is claimed is:

1. A shooting method, comprising steps of:
defining at least two sub-regions on a screen;
shooting photos after performing white balance adjustment by taking the at least two sub-regions as colour temperature reference regions;
determining a selected colour temperature reference region on one of the shot photos; and
picking a photo shot after performing the white balance adjustment according to the selected colour temperature reference region out of the shot photos, and displaying the photo;
wherein the step of shooting the photos after performing the white balance adjustment by taking the at least two sub-regions as the colour temperature reference regions comprises:
obtaining colour temperature values of the at least two sub-regions by taking each sub-region as a colour temperature reference region, and obtaining a colour temperature value of the whole screen by taking the whole screen as a colour temperature reference region;
calculating a weighted average of the colour temperature value of each sub-region and the colour temperature value of the whole screen to obtain at least two weighted averages; and
shooting at least two photos performing the white balance adjustment on the screen according to the at least two weighted averages respectively.

2. The shooting method according to claim 1 , wherein the step of determining a selected colour temperature reference region on one of the shot photos comprises:
displaying a selection pattern on one of the shot photos; and
moving the selection pattern according to operation, and determining the sub-region corresponding to a position of the selection pattern as the selected colour temperature reference region.

3. The shooting method according to claim 1 , wherein the step of determining a selected colour temperature reference region on one of the shot photos comprises:
determining a position where one of the shot photos is touched or clicked; and
determining the sub-region corresponding to the position as the colour temperature reference region.

4. A shooting method, comprising steps of:
displaying a selection pattern on a photo;
determining a colour temperature reference region according to a position of the selection pattern; and
picking a photo shot after performing white balance adjustment according to the colour temperature reference region out of the shot photos, and displaying the photo;
wherein the method further comprises: before the step of displaying the selection pattern on the photo, defining at least two sub-regions on a screen; and
shooting at least two photos after performing the white balance adjustment by taking each of the at least two sub-regions as a colour temperature reference region;
wherein the step of shooting the at least two photos after performing the white balance adjustment by taking each of the at least two sub-regions as the colour temperature reference region comprises:
obtaining colour temperature values of the at least two sub-regions by taking each of the at least two sub-regions as a colour temperature reference region, and obtaining a colour temperature value of the whole screen by taking the whole screen as a colour temperature reference region;
calculating a weighted average of the colour temperature value of each sub-region and the colour temperature value of the whole screen to finally obtain at least two weighted averages; and
shooting the at least two photos after performing the white balance adjustment on the screen according to the at least two weighted averages respectively.

5. The shooting method according to claim 4 , wherein the step of determining the colour temperature reference region according to the position of the selection pattern comprises:
determining a sub-region corresponding to the position of the selection pattern; and
taking the sub-region as the colour temperature reference region.

6. A shooting device, comprising: a shooting module configured to shoot photos for a screen;
a display module configured to display the screen and photos, and display a selection pattern on the photos; and
a processing module configured to move position of the selection pattern, determine a colour temperature reference region according to the position of the selection pattern, pick a photo shot after performing white balance adjustment according to the colour temperature reference region out of the shot photos and control the display module to display the photo;
wherein the shooting module is configured to: define at least two sub-regions on the screen, and shoot at least two photos after performing the white balance adjustment by taking each of the at least two sub-regions as the colour temperature reference region;
wherein the shooting module is configured to: calculate the colour temperature value of each sub-region to finally obtain the colour temperature values of the at least two sub-regions; obtain a colour temperature value of the whole screen by taking the whole screen as a colour temperature reference region; calculate a weighted average of the colour temperature value of each sub-region and the colour temperature value of the whole screen to finally obtain at least two weighted averages; and perform the white balance adjustment on the screen according to the at least two weighted averages respectively.

7. The shooting device according to claim 6 , wherein the processing module is configured to: determine a sub-region corresponding to the position of the selection pattern and take the sub-region as the colour temperature reference region.

8. A shooting method, comprising steps of:
receiving an operating instruction for a photo;
determining a colour temperature reference region according to the operating instruction; and
picking a photo shot after performing white balance adjustment according to the colour temperature reference region out of the shot photos, and displaying the photo;
wherein the method further comprises: before the step of receiving the operating instruction for the photo, defining at least two sub-regions on a screen; and
shooting at least two photos after performing white balance adjustment by taking each of the at least two sub-regions as the colour temperature reference region;
wherein the step of shooting the at least two photos after performing the white balance adjustment by taking each of the at least two sub-regions as the colour temperature reference region comprises:
obtaining colour temperature values of the at least two sub-regions by taking each of the at least two sub-regions as a colour temperature reference region, and obtaining a colour temperature value of the whole screen by taking the whole screen as a colour temperature reference region;
calculating a weighted average of the colour temperature value of each sub-region and the colour temperature value of the whole screen to finally obtain at least two weighted averages; and
shooting the at least two photos after performing the white balance adjustment on the screen according to the at least two weighted averages respectively.

9. The shooting method according to claim 8 , wherein the operating instruction comprises touch or clicking operation performed on the photo, and the step of determining the colour temperature reference region according to the operating instruction comprises:
determining a sub-region corresponding to a position where the photo is touched or clicked; and
taking the sub-region as the colour temperature reference region.
