Embodiment
[0026] see Figure 1 to Figure 4 , the present invention provides a technical solution:
[0027] A medical fundus image processing device, comprising:
[0028] The housing 1 has an opening 101 on the side wall of the housing 1. On the optical axis corresponding to the opening 101, an objective lens 2, a perforated mirror 3, a focusing lens 4, an imaging lens 5, an image sensor 6, and an objective lens 2 are sequentially arranged. The outer periphery of the peripheral plate 201 is fixedly provided with a peripheral plate 201, the top of the peripheral plate 201 is provided with a groove 202, and the optical axis of the reflection direction of the perforated mirror 3 is sequentially provided with a configuration lens 7, a dichroic mirror 8, a first converging lens 9 and an observation light source 10. A second converging lens 11 and a shooting light source 12 are sequentially arranged on the optical axis of the dichroic mirror 8 in the reflection direction, and the dichroic mir...

The invention provides a medical eye fundus image processing device. An opening is formed in the side wall of a shell, and an objective lens, a perforated lens, a focusing lens, a camera lens and an image sensor are sequentially arranged on an optical axis corresponding to the opening; a hue conversion unit, a hue selection unit, a single color conversion unit, a gray scale conversion unit and a PLC are arranged in a partition plate; a rotating cover is movably and rotatably arranged on the outer side of a cylindrical base, a conductive plate can conduct electricity when making contact with a trigger switch panel, and a cleaning pad is fixedly arranged on the inner wall of a downward-concave part; and a cleaning brush is used for cleaning the cleaning pad. According to the medical eye fundus image processing device, the rotating cover is arranged in the medical eye fundus image processing device, the light emitting amount of an observation light source can be adjusted during forward rotation, a related structure is driven to clean the cleaning pad, the downwards-concave part can be pushed during reverse rotation, the clean cleaning pad cleans the two faces of the objective lens, and observation clarity is effectively improved.
Description
technical field [0001] The invention relates to the technical field of ophthalmic equipment, in particular to a medical fundus image processing device. Background technique [0002] In the prior art, the application number is "201210267121.3", an image processing device and an image processing method for fundus images. The image processing device includes: a selection unit for selecting the first tone conversion process or the second tone conversion process, wherein, The second tone conversion process sets the ratio of the red wavelength component lower than the blue wavelength component or the green wavelength component with respect to the first tone conversion process; and a tone conversion unit for converting the tone of the fundus image by the selected tone conversion process . [0003] However, there are still obvious defects in its use: the objective lens in the above-mentioned device is very easy to adhere to impurities such as dust after long-term use, which interfe...
