  • Patent number: 11988824
    Abstract: The present invention concerns a method for producing a microscopic image with an extended depth of field by means of a microscope. The microscope comprises an images sensor that comprises pixels that are arranged as a matrix that is formed by lines. In a step of the method, a plurality of microscopic frames of a specimen is acquired while a focus position (z) is changed. The microscopic frames are acquired line by line. The focus position (z) is changed over a course of acquiring individuals of the microscopic frames. In a further step, parts of individuals of the acquired lines are identified. These parts sharply image the specimen. The identified parts of the lines are composed in order to form a microscopic image of the specimen with an extended depth of field. Furthermore, the present invention concerns a microscope.

  • Patent number: 11705075
    Abstract: A display device includes a display panel, a first memory, and a degradation compensator. The first memory device stores stress data including degradation values representing a degradation degree of each of the blocks in the display panel. The degradation compensator loads the stress data from the first memory device, updates the stress data based on current input data and a maximum degradation value, updates the maximum degradation value based on degradation values included in the updated stress data, and generate compensated data by compensating for the current input data based on the updated stress data. The degradation compensator determines whether a first degradation value included in the stress data is normal by comparing the first degradation value with the maximum degradation value, and updates the first degradation value based on at least one adjacent degradation value adjacent to the first degradation value, when the first degradation value is abnormal.
