Abstract: A device for projecting a test pattern for evaluating the image-capturing properties of a lens module includes a light emitting assembly. The light emitting assembly includes a light emitter and a patterning plate on the light emitter. The patterning plate includes a first surface facing the light emitter and a second surface opposite to the first surface. The second surface is concave and defines a patterning groove. The light from the light emitter passes through the patterning groove to form an original pattern for testing, the display of a test pattern being instantly selectable and displayable.

Abstract: A method for testing an autofocus function of a camera module fixes a camera module and at least two test members sequentially spaced at different positions on an axis pointing straight away from the camera. The camera module is controlled to focus and capture images of each test member and record driving currents of the camera module to achieve those focuses at those distances. When a sharpness of image of a test member reaches a preset threshold value a correspondence table between the driving currents and object distances is generated. An autofocus testing device is further provided.

Abstract: A method for sorting and recycling garbage recycles garbage of certain types into a garbage collecting device, the garbage recycling device implements the method and includes a temporary storage box and a storage box having an inlet. The method acquires an image of garbage in the temporary storage box, analyzes the image to obtain a first classification information and determines whether the first classification information matches a recycling category. The inlet of the storage box is opened when the first classification information matches a certain recycling category. A garbage sorting and recycling system and a computer readable storage medium are also provided.
