Abstract: The present application provides a system and a method for acquiring an image, an electronic device, and a computer-readable storage medium. The system for acquiring an image provided in the present application provides a correction reference with uniform illumination by adjusting the positional relationship between the light source and the correction reference, and acquires at least one image of the correction reference by the image acquisition device to be corrected. Wherein, the correction image obtained based on the at least one image may be used to perform lens shading correction on the image acquisition device. The system for acquiring an image does not require the use of an expensive integrating sphere, which may reduce purchase and maintenance costs of a testing device for obtaining a correction image.

Abstract: Embodiments provide a screw, a food processing cup assembly, and a food processor. The screw includes a screw body including a feeding area for feeding and a crushing area connected to the feeding area; a first spiral rib is spirally arranged on the feeding area along the axial direction of the screw body, and extending to the crushing area along a top of the screw body; a cutting surface extending from the top of the screw body to the crushing area; second spiral ribs are disposed on the screw body at intervals along the axial direction of the screw body.

Abstract: The present disclosure provides a screw, a food processing cup assembly, and a food processor. The screw comprises a screw body including a feeding area for feeding and a crushing area connected to the feeding area; a first spiral rib is spirally arranged on the feeding area along the axial direction of the screw body, and extending to the crushing area along a top of the screw body; a cutting surface extending from the top of the screw body to the crushing area; a plurality of second spiral ribs are disposed on the screw body at intervals along the axial direction of the screw body. By setting the first spiral rib and the cutting surface, when the food materials first enter the feeding area, they can be supported by the concave cutting surface and cut by the first spiral rib, which effectively prevents the occurrence of food materials slipping, reduces the auxiliary squeeze of pushing rod, and improves the convenience of operation.
