Embodiment Construction
[0026] An ultra-high bit-width image enhancement display device for a medical professional display, which includes: an ultra-high bit-width image enhancement display device for a medical professional display, characterized in that it includes: a bit width expansion module, a shaking module and a frame control module. Among them, the bit width expansion module actually stores a LUT lookup table that expands the data bit width from 10bit / 12bit to correspond to 16bit, 17bit, 18bit, 19bit and 20bit bit width data. The method of making the lookup table is determined by the above-mentioned expansion method of increasing the data bit width of a medical professional display. The dithering module adopts a dynamic dithering algorithm, which mainly increases the gray scale of the image display by modulating the spatial relationship between pixel data. The dithering algorithm generally uses a dithering matrix for comparison operations. The value in the matrix corresponds to a small pixel, ...

The invention discloses a superhigh bit width image enhancement display device and method for a medical professional display, and the device is characterized in that the device comprises a bit width extension module, a jitter module, and a frame control module; the device and method are used for the enhancement display of five random superhigh bit width images (16bit, 17bit, 18bit, 19bit, and 20bit), and achieve the precise description of a screen characteristic curve of any superhigh bit width data; the value of the device lies in increasing the number of image gray levels and color types, recognizing a potential focus of infection more easily, improving the display precision, reducing the error of the description of the screen characteristic curve, and helping a doctor improve the diagnosis efficiency and accuracy of the focus of infection of a patient.
Description
technical field [0001] The invention relates to an ultra-high-bit-width image enhancement display device and method for a medical professional display. Background technique [0002] Color depth, referred to as color depth (ColorDepth), is a unit that uses the number of bits to represent the number of colors displayed by digital cameras, monitors, scanners and other display devices. It is also an important reference index for measuring the color display capabilities of the above display devices. However, many manufacturers generally use bit width instead of color depth in order to describe the color display capabilities of their display products to the public more intuitively and vividly. At present, the mainstream bit width of ordinary civilian displays such as home computers and notebooks is only 8 bits, which can display 256 gray scales and present 16,777,216 colors. However, in the field of medical display, due to the special needs of medical diagnosis, the mainstream me...
