Abstract:
A detection method for an image acquisition device, a detection device for an image acquisition device, an electronic device and a computer readable storage medium are disclosed. The image acquisition device includes a light source and a diffuser, the diffuser is configured to scatter light emitted by the light source and the light emitted by the light source is irradiated on at least partial area of a scene, the image acquisition device includes: acquiring an image of the scene; determining an effective area of the image; and determining whether or not the diffuser is in an abnormal working state according to information of the effective area.

Claim (Index 14):
The detection method according to  claim 1 , wherein determining of the effective area of the image is conducted by covering the image with a pre-set pattern; and\n wherein determining of the effective area of the image by covering the image with the pre-set pattern comprises:\n obtaining a total amount of effective signals of the image; \n obtaining a first ratio through calculating a ratio of an amount of effective signals in a region, which is covered by the pre-set pattern, of the image to the total amount of effective signals; \n outputting prompt information that an abnormity is present or a size of the pre-set pattern is small in a case where the first ratio is less than or equal to the preset ratio; \n determining the effective area of the image based on a new pre-set pattern, a size of which is smaller than a size of the pre-set pattern in a case where the first ratio is larger than the preset ratio, wherein determining of the effective area of the image based on the new pre-set pattern comprises:\n obtaining a second ratio through calculating a ratio of an amount of effective signals in a region, which is covered by the new pre-set pattern, of the image to the total amount of effective signals; \n setting a region, which is covered by a previous pre-set pattern, of the image as the effective area of the image in a case where the second ratio is less than or equal to the preset ratio, wherein the new pre-set pattern covers the image immediately after the previous pre-set pattern; and \n using another new pre-set pattern, a size of which is smaller than the size of the new pre-set pattern, to conduct determining of the effective area of the image based on the another new pre-set pattern in a case where the second ratio is larger than the preset ratio.
