Abstract: A hand-held fluorescence microscope is disclosed, including: a partial-spectrum light source, a first filtering device, a second filtering device, and an image sensor arranged inside a housing of the hand-held fluorescence microscope. The partial-spectrum light source generates a first light beam. The first filtering device filters the first light beam to provide a second light beam. The second filtering device filters a fluorescence generated by a specimen after receiving the second light beam to provide a fourth light beam. The image sensor receives the fourth light beam to generate fluorescence images. One end of the housing is provided with a light mask for surrounding the specimen to avoid external light from being entering the image sensor. The light path of the second light beam projecting to the specimen does not overlap with the light path of the fluorescence radiating from the specimen to the second filtering device.

Abstract: A computer program product capable of enabling a computer to perform a digital image analyzing operation, wherein the digital image analyzing operation comprises: receiving settings of a plurality of lines corresponding to one or more image edges of a digital image; and identifying a plurality of intersections of the plurality of lines and the one or more image edges of the digital image.

Abstract: A digital microscope is disclosed including: an image sensing circuit having an image sensing area thereon; a first object lens aligned with the image sensing area along an axis; a luminance device positioned outside the axis for emitting light toward a direction that is not coaxial with the axis; a light redirector positioned outside the axis for redirecting the light emitted from the luminance device; and a beam splitter positioned on the axis for changing the direction of light from the light redirector to provide an output light that is outputted substantially along the axis and coaxial with the axis; wherein the first object lens is positioned between the image sensing area and the beam splitter.

Abstract: A digital imaging apparatus is disclosed including: a light source module; an image synchronization signal generator for generating an image synchronization signal; and a light source controller, coupled with the light source module and the image synchronization signal generator, for generating a light source control signal having a frequency corresponding to the image synchronization signal and synchronized with the image synchronization signal to control the light output of the light source module.
