A method for recording an image. The method includes: detecting an area using a sensor and generating a map of the area having a predefined number of pixels, which indicate brightness values, and subdividing the map into blocks) having a predefined first size, creating an auxiliary map by scaling down the blocks to a predefined second size, which is smaller than the predefined first size, sorting the pixels of each block of the auxiliary map according to their brightness values, determining processing parameters for each block on the basis of the sorted pixels, with which the pixels of the associated block are processed in order to achieve a brightness maximization and/or a contrast maximization, interpolating a processing function from the processing parameters, and applying the processing function to the pixels of the map to generate the image.

An image capture device may include an image sensor, a processor, and a memory. The image sensor may be configured to obtain an image. The processor may be configured to generate a grid on the image. The grid may include one or more vertices. The one or more vertices may be used to form tiles. The processor may be configured to determine a flare level of each vertex. The processor may be configured to assign a maximum flare level for each tile of the image. The processor may be configured to sort the tiles. The tiles may be sorted based on the maximum flare level of each tile. The processor may be configured to apply a flare compensation to a subset of the tiles to obtain a processed image. The processed image may have reduced flare artifacts or no flare artifacts. The processed image may be stored in the memory.

A transmission device including circuitry is provided. The circuitry is configured to apply photoelectric conversion characteristics to high dynamic range video data to obtain transmission video data. The circuitry is configured to transmit a container including a video stream obtained by encoding the transmission video data. The circuitry is configured to insert type information to designate the type of conversion characteristics corresponding to the applied photoelectric conversion characteristics for photoelectric conversion of the transmission video data into a layer of the video stream and/or a layer of the container.
