Inventor: ARTAL SORIANO PABLO LUIS
IPC: A61B3/10
Filed: 2022-04-01
Abstract: An ophthalmic instrument for measuring optical quality of an eye (1) includes a multi-element eyepiece (35) and a rotatable mirror (11). A first focal plane (2) of the multi-element eyepiece (35) in an object space is optically conjugated with a scanning surface of the rotatable mirror (11) through a first lens (10). A focal point of the first lens (10) is arranged in a virtual focal plane (30) of the multi-element eyepiece (35). The multi-element eyepiece (35) includes an eyepiece (4), a field lens and a second lens (8) arranged in sequence. The field lens includes a third lens (5), a fourth lens (6) and a fifth lens (7) arranged in sequence. The eyepiece (4), the third lens (5), the fourth lens (6) and the fifth lens (7) each is a positive lens and the second lens (8) is a negative lens. When a retina is illuminated by flying spot light from any field of view, light from an exit pupil of the eye is obtained by the flying spot light being reflected and scattered by respective retinal sites. A light beam carrying information about the optical quality of the eye is stably transmitted by the rotatable mirror (11) through the multi-element eyepiece (35) to an optical sensor for analyzing optical imaging quality. A topography of a diopter of the retinal can be measured quickly in a case that a patient does not change a viewing angle and the measurement is not interrupted.

Abstract: An image light supplementation method and an electronic device are disclosed. In the method, instead of using supplemented light from an external device, the electronic device first obtains a to-be-processed image, where a side of a face of a first user in the to-be-processed image lacks illumination, causing the side to be darker. Then, a first image is obtained from the to-be-processed image, where the first image is a part of the to-be-processed image that includes the face of the first user. Then, an albedo image and an illumination image of the first image are calculated, and light supplementation is performed on the first image by using the albedo image and the illumination image, to obtain a light-supplemented first image. In the light-supplemented first image, both sides of the face of the first user are clear and not darker, which is more in line with aesthetics of human eyes. Then, the electronic device replaces the first image in the to-be-processed image with the light-supplemented first image.
