Embodiment 1

[0047] Such as Figure 2A As shown, in the step 2, the preset hue range 210 includes a red range 211, a magenta range 212, and a purple range 213, and the hue balance unit 200 uses the first hue balance mapping curve one 214 to convert the red range 211 expands towards the magenta range 212 while compressing the violet range 213 for hue balance.

Embodiment 2

[0049] Such as Figure 2B As shown, in the step 2, on the basis of the first embodiment, the preset hue range 220 also includes an orange range 221, a yellow range 222, and a grass green range 223, and the hue balance unit 200 adopts the second hue The second balance mapping curve 224 expands the orange-yellow range 221 to the yellow range 222 while compressing the grass-green range 223 to achieve color balance.

Embodiment 3

[0051] The hue balance unit 200 uses the hue histogram 230 within the preset hue range 210 to calculate the cumulative hue probability distribution density, dynamically generates a third hue balance mapping curve, and replaces the first hue balance mapping with the third hue balance mapping curve curve, in this embodiment, the preset hue range 210 is the preset hue range 210 in Embodiment 1. details as follows:

[0052] see image 3 , the hue histogram 230 includes at least two hue bins 231, each hue bin 231 contains a number of pixels 232 in the hue range, and each hue bin 231 counts a frame of image falling within the range of the hue bin 231 The number of pixels is 232, all the hue bins 231 do not overlap and occupy the preset hue range 210 after splicing. The hue center value 233 of each hue cabinet 231 is denoted as Hue_in(i), the number of pixels 232 of each hue cabinet 231 is denoted as Hist(i), i∈[1,N], and N is the total number of hue cabinets 231 .

Abstract

The invention discloses an endoscope camera image processing device, comprising: a first color coordinate conversion unit, a hue balance unit and a second color coordinate conversion unit. The red, green, and blue primary color image is converted into a brightness chroma hue image by the first color coordinate conversion unit, at least a part of the hue within the preset hue range is expanded by the hue balance unit, and at least another part of the preset hue range is compressed at the same time. Part of the hue is used to achieve hue balance, and finally the brightness, chroma, and hue images are converted into red, green, and blue primary color images by the second color coordinate conversion unit for viewing by doctors. The invention has remarkable color balance effect, and can solve the problem of visual fatigue easily caused by surgeons staring at endoscopic medical images mainly in red tone for a long time.

Description

technical field [0001] The invention relates to the field of medical imaging, in particular to an endoscope camera image processing device and method. Background technique [0002] Endoscopic camera is a widely used medical device, relying on the aid of light sources, it enters the human body through the natural orifice of the human body or a small incision made by surgery, and when used, the endoscope is introduced into the organ to be inspected, and the relevant parts can be peeped directly To make a disease diagnosis or take a biopsy of the lesion for pathological diagnosis. At the same time, the disease can be treated in time or artificial products with therapeutic effects can be implanted. [0003] Medical image processing is an important part of endoscopic cameras. Different from consumer or industrial cameras, medical image processing needs to solve the unique difficulties and problems faced by medical images, improve the efficiency of diagnosis and minimally invasive...
