Image bit width conversion method and device based on histogram statistics

The invention discloses an image bit width conversion method and device based on histogram statistics, relates to the technical field of image processing, obtains an image correction value on the basis of gray histogram statistics, completes bit width conversion based on the image correction value, does not need complex operations such as image cutting, is low in calculation overhead, occupies few logic resources, and is high in efficiency. And the portability is high, any output bit width of the infrared camera can be converted very conveniently, and subsequent image processing is facilitated. 本发明公开了一种基于直方图统计的图像位宽转换方法及装置，涉及图像处理技术领域，以灰度直方图统计为基础，获取了图像修正值，并基于该图像修正值完成位宽转换，不需要进行图像切割等复杂运算，计算开销小，占用逻辑资源少，可移植性强，可以十分便捷的对红外相机任意输出位宽进行转化，方便后续图像处理。
