Exemplary embodiments provide microscope devices and methods for forming and using the microscope devices. The microscope device can include a light emitter array with each light emitter individually addressable to either emit or detect light signals. Magnified images of a sample object can be generated by a reflection mechanism and/or a transmission mechanism using one or more microscope devices in an imaging system. Real-time computer control of which microscope pixels are viewed can allow the user to digitally replicate the “fovea” function of human vision. Viewing an object from both sides in the double-sided microscope system and from multiple pixel positions can allow the microscope to reconstruct pseudo-3D images of the object.

The invention relates to a method for processing a microscope video image, in particular to an exposure processing method of a digital microscope image, which is characterized in that: for the characteristics that the illumination of an optical microscope digital image system is not uniform, an exposure situation is determined according to a brightness histogram so as to adjust the exposure time; and a brightness gain curve is drawn according to a pure background slice-free background image to obtain a brightness gain equation, and a brightness adjusting factor when the brightness of the pure background slice-free background image is adjusted to be uniform can be calculated through the equation. Under the same condition, a brightness value of a pixel point corresponding to a sliced image is adjusted through the brightness adjusting factor to obtain the brightness homogeneity of the image. Due to the adoption of the method, the homogeneity adjustment of the video image of the optical microscope digital image system can be precisely realized.

The invention discloses a woven fabric count detector based on a digital microscope, belonging to the field of novel spinning detection instruments. Fabric count refers to the quantities of warp and weft yarns within a unit length of a fabric. The conventional manpower-dependent detection method has the defects of time and labor wasting and high subjectivity, and cannot meet the requirement of spinning production automation obviously. Specific to the technical problem, the digital microscope is taken as image acquisition hardware, and automatic detection of fiber count is realized in combination with an image processing method, so that an automatic woven fabric count detection instrument is realized. A CCD (Charge Coupled Device) digital camera is used for acquiring a fiber surface image amplified by a microscope objective, and a fiber image is read into a computer through a USB (Universal Serial Bus) or an IEEE1394 interface. The obtained fiber image is subjected to Fourier transform, and separation of warp yarns from weft yarns in the fiber image is realized with a frequency domain filtering method. The quantities of warp and weft yarns within certain lengths are counted in a separated single group yarn image, so that the woven fabric count is computed automatically.
