Abstract: Image exposure in an ophthalmic microscope device is controlled by first recording a camera image with the camera of the microscope using first exposure parameters. Edge detection, e.g., based on convolution using a discrete differential operator, is then used to identify regions where the image has high and low edge densities. A brightness parameter of the camera image is calculated by weighing the pixel brightness in the regions with increased edge density more strongly than in the other regions. The brightness parameter is then used to control the exposure parameters of the microscope.

Abstract: Aspects of the disclosure provide methods and apparatuses for video encoding/decoding. In some examples, an apparatus for video decoding includes receiving circuitry and processing circuitry. For example, the processing circuitry decodes prediction information of a current block in a current coding tree unit (CTU) from a coded video bitstream. The prediction information is indicative of an intra block copy mode. A size of the current CTU is smaller than a maximum size of a reference sample memory for storing reconstructed samples. The processing circuitry determines a block vector that points to a reference block in a same picture as the current block. The reference block has reconstructed samples buffered in the reference sample memory. Then, the processing circuitry reconstructs at least a sample of the current block based on the reconstructed samples of the reference block that are retrieved from the reference sample memory.

In addition to scaled readouts of image data, some variants may also provide commonly used data and/or implement pre-processing steps.
