Output picture correction method and device and storage medium

The invention provides an output picture correction method and device and a storage medium, and the method comprises the steps: transmitting a test image to a target display device, so as to indicate the target display device to display the test image; obtaining color analysis data of an output picture when the target display device displays the test image; according to the color analysis data and target color data corresponding to the test image, generating tone mapping data corresponding to the target display device, the tone mapping data being used for representing a mapping relationship between an original color value and a corrected color value of the test image, the corrected color value is used for driving the target display equipment to output an image conforming to the target color data; and correcting the output picture of the target display equipment by adopting the tone mapping data. The effect of the display device is automatically corrected according to the test image, so that the display device
