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 18):
The detection device according to  claim 17 , 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; and \n comparing the first ratio with a preset ratio to obtain a comparison result, and obtaining the effective area of the image based on the comparison result; \n wherein determining of whether or not the diffuser is in the abnormal working state according to the information of the effective area comprises:\n determining that the diffuser is in the abnormal working state if an area of the effective area is less than or equal to a preset area; or \n determining that the diffuser is in the abnormal working state if a ratio of an area of the effective area to an area of the image is less than or equal to a preset area ratio.
