For meeting the future demand of high quality yet economically feasible high dynamic range video program creation, the inventor proposes a method of in a video camera (201) setting a video camera capturing mode of specifying output pixel luminances in one or more graded versions of output video sequences of images, comprising: —an operator of the video camera moving to at least two positions (Pos1, Pos2) in a scene which have a different illumination compared to each other, and capturing at least one high dynamic range image (o_ImHDR) for each of those at least two positions of the scene; —a color composition director analyzing for each of the at least two positions the captured at least one high dynamic range image to determine a region of maximum brightness, and determining at least one of an iris setting, a shutter time, and an analog gain setting for the camera; —capturing for each position of one of the at least two positions (Pos1, Pos2) a respective master capturing (RW) using the at least one of an iris setting, a shutter time setting, and an analog gain setting for the camera, and keeping iris, shutter time and analog gain settings constant for later capturing in at least the corresponding position; —determining at least a respective first graded image (ODR) for the respective master capturing, which consists of mapping by a respective luminance allocation function (FL_M) of digital numbers of the master capturing to nit values of the first graded image (ODR), by the color composition director establishing a shape of such luminance allocation function; and —storing the respective luminance allocation functions (Fs1, Fs2) for the at least two positions, or parameters uniquely defining these functions, in respective memory locations (221, 222) of the camera.

The application provides a log storage method, device, electronic equipment and storage medium, wherein the log storage method comprises: obtaining a file instance used for processing a to-be-stored log; encoding an attribute field in the to-be-stored log to obtain a first byte stream corresponding to a digital number and storing the first byte stream in a block cache area; compressing the byte stream in the block cache area based on the file instance to obtain a second byte stream; encrypting the second byte stream in the compressed cache area based on the file instance to obtain a third byte stream; and writing the third byte stream into a byte stream file based on the file instance, wherein the byte stream file comprises a file block and a file header, and the third byte stream is stored in the file block. The application can write the to-be-stored log into the byte stream file without the aid of a third-party data storage tool. On the other hand, the application can obtain a byte stream file with smaller storage space by encoding and compressing the to-be-stored log.

This invention relates to data processing and digital healthcare technology, disclosing a method, apparatus, device, and storage medium for connecting uppercase numbers on medical invoices in scenarios such as data auditing, management, and warehousing of medical invoices. The method includes: detecting uppercase numbers on the medical invoice to obtain a set of text box objects; grouping the text box object set into anchor box objects and boxes to be connected, constructing target search boxes for the medical invoice based on the anchor box objects and the boxes to be connected; performing a secondary text search on the target search boxes based on the object type of the anchor box objects in the target search boxes to obtain candidate combination text boxes, or performing a text search to obtain candidate text boxes; and concatenating the candidate combination text boxes and their coordinate information to obtain the uppercase number concatenation result. This invention can improve the accuracy of identifying and connecting printed and digital numbers on invoices in various medical invoice recognition processes.
