Abstract

Imaging control methods and apparatuses are provided related to the field of imaging. A method comprises: in response to that an imaging apparatus is ready for reading data of a line of pixels, acquiring light source information of at least one glare source corresponding to the line of pixels, the at least one glare source being at least one of at least one light source of the imaging apparatus, causing a glare of the line of pixels when being in an ON state; and turning off at least one light source in an ON state in the at least one glare source according to the light source information. The influence of glare can be reduced, thereby improving the image quality.

Claims

1. A method, comprising:

in response to determining that a proportion of glaring pixels in a line of pixels is greater than a threshold, determining that the line of pixels has a glare;

in response to determining that an imaging device is ready for reading data of the line of pixels, acquiring, by a system comprising a processor, light source information of at least one glare source corresponding to the line of pixels, the at least one glare source being at least one light source of the imaging apparatus, causing the glare of the line of pixels when being in an ON state; and

turning off the at least one light source in the ON state in the at least one glare source according to the light source information.

2. The method of claim 1, wherein the light source information of the at least one glare source corresponding to the line of pixels is acquired according to a correspondence between the line of pixels and the at least one glare source.

3. The method of claim 1, further comprising:

predetermining the at least one glare source corresponding to the line of pixels.

4. The method of claim 3, wherein the predetermining the at least one glare source corresponding to the line of pixels comprises:

turning on the at least one light source; and

determining the at least one glare source corresponding to the line of pixels according to whether the line of pixels has the glare.

5. The method of claim 3, wherein the predetermining the at least one glare source corresponding to the line of pixels comprises:

turning on the at least one light source in groups; and

determining at least one group of the at least one light source as the at least one glare source corresponding to the line of pixels according to whether the line of pixels has the glare.

6. The method of claim 4, wherein, a brightness value of the glaring pixel is greater than a predetermined brightness value.

7. The method of claim 6, wherein, the glaring pixel has a predetermined number of adjacent pixels having brightness values that are greater than the predetermined brightness value.

8. The method of claim 1, further comprising:

turning on another light source in the at least one light source except for the at least one glare source.

9. The method of claim 1, wherein the imaging apparatus is an electronic rolling shutter-type imaging apparatus.

10. The method of claim 9, wherein the at least one light source is at least two light sources, and the at least two light sources are distributed along a rolling direction of the electronic rolling shutter-type imaging apparatus.

11. An apparatus, comprising:

a memory that stores executable modules; and

a processor, coupled to the memory, that executes or facilitates execution of the executable modules, comprising;

a predetermining module configured to, in response to a determination that a proportion of glaring pixels in a line of pixels is greater than a threshold, determine that the line of pixels has a glare;

an acquiring module configured to;

in response to a determination that an imaging apparatus is ready for reading data of the line of pixels, receive light source information of at least one glare source corresponding to the line of pixels, the at least one glare source being at least one light source of a set of light sources of the imaging apparatus, causing the glare of the line of pixels when being in an ON state; and

an executing module configured to turn off the at least one light source in the ON state in the at least one glare source according to the light source information.

12. The apparatus of claim 11, wherein the acquiring module receives the light source information of the at least one glare source corresponding to the line of pixels according to a correspondence between the line of pixels and the at least one glare source.

13. The apparatus of claim 11, wherein:

the predetermining module is further configured to predetermine the at least one glare source corresponding to the line of pixels.

14. The apparatus of claim 13, wherein the predetermining module is configured to turn on the at least one light source, and determine the at least one glare source corresponding to the line of pixels according to whether the line of pixels has the glare.

15. The apparatus of claim 13, wherein the predetermining module is configured to turn on the at least one light source in groups, and determine at least one group of the light source as the at least one glare source corresponding to the line of pixels according to whether the line of pixels has the glare.

16. The apparatus of claim 11, wherein the executing module is further configured to turn on a light source of the set of light sources other than the at least one glare source.

17. The apparatus of claim 11, wherein the imaging apparatus is an electronic rolling shutter-type imaging apparatus.

18. The apparatus of claim 17, wherein the at least one light source is at least two light sources, and the at least two light sources are distributed along a rolling direction of the electronic rolling shutter-type imaging apparatus.

19. A non-transitory computer readable medium, comprising at least one executable instruction, which, in response to execution, causes an apparatus comprising a processor to perform operations, comprising:

in response to determining that a proportion of glaring pixels in a line of pixels is greater than a threshold, determining that the line of pixels has a glare;

in response to determining that an imaging device is ready for reading data of the line of pixels, acquiring light source information of at least one glare source corresponding to the line of pixels, the at least one glare source being at least one of a group of light sources of the imaging apparatus, causing the glare of the line of pixels when being in an ON state; and

turning off the at least one of the group of light sources in the ON state in the at least one glare source according to the light source information.

20. An apparatus, characterized by comprising a processor and a memory, the memory storing executable instructions, the processor being connected to the memory via a communication bus, and when the imaging control apparatus operates, the processor executing or facilitating the executing of the executable instructions stored in the memory, so that the imaging control apparatus executes operations, comprising:

in response to determining that a proportion of glaring pixels in a line of pixels is greater than a threshold, determining that the line of pixels has a glare;

in response to determining that an imaging device is ready for reading data of the line of pixels, receiving light source information of a glare source corresponding to the line of pixels, the glare source being a light source of the imaging apparatus causing the glare of the line of pixels when being in an ON state; and
