Abstract
An image data processing device includes a data acquisition module for acquiring image data including original data information of images, the original data information of each image including the luminance value of each pixel in the image, and the luminance range that the image data may represent being Lmin-Lmax; a data conversion module for receiving the image data and converting the original data information of each image into new data information; and a data output module for outputting the new data information of each image in the data conversion module together with the corresponding maximum relative luminance value η thereof. A capturing equipment and a display system are also provided.
Claims11
An image data processing device, configured to:
- acquire image data, wherein the image data comprise original data information of at least two frames of an image, and original data information of each frame of the image comprises brightness values of pixels on the frame of the image;
- and a maximum possible brightness that the image data is capable of rendering is Lmax and a minimum possible brightness that the image data is capable of rendering is Lmin;
- receive the image data and convert the original data information of each frame of image in the image data into new data information,
- wherein said converting the original data information of each frame of the image in the image data into the new data information comprises:
- acquiring a maximum brightness value L1 of pixels of the image frame;
- taking L1/Lmax as a maximum brightness relative value η of the image frame where L1≥0, and Lmax is a positive number greater than 0;
- amplifying a brightness value of each of the pixels in the image frame to 1/η times of an original brightness value of each of the pixels, so as to achieve an amplified brightness value, where the original brightness value is greater than or equal to 0, and 1>η>0;
- and
- setting the amplified brightness value to 0 if the amplified brightness value is smaller than Lmin1, wherein Lmax>Lmin1>Lmin;
- and
- output the new data information of each frame of the image and the maximum brightness relative value η corresponding to the new data information.
