Problems solved by technology

However, when selecting the picture of the specific location of the lesion, since the display screen changes with the change of the lesion, it is necessary for the patient to cooperate repeatedly to obtain the image of the location.
It not only brings the pain of detection to patients, but also prolongs the detection time of doctors

Embodiment Construction

[0013] Such as figure 1 As shown, the lesion to be measured is imaged on the target surface of the CCD device using an endoscope 1 with a CCD, and the video signal output by the front end is sent to the DSP digital signal processor 4 for processing after being sampled, held, and A / D conversion circuit 2. On the one hand, the compressed data is temporarily stored in the attached FLASH memory 3, and then the image is displayed on the display 7 through the video output port 6 (AV terminal, S terminal, VGA port, etc.).

[0014] Such as figure 2 As shown, the endoscope 1 of the CCD images the lesion to be measured on the target surface of the CCD device, and the video signal output by the front end is sent to the DSP digital signal processor 4 for processing after being sampled, held, and A / D conversion circuit 2. The imaging on the target surface of the CCD device can have dozens of frames in 1 second through the video output, and the image displayed on the display 7 by the DSP ...

Abstract

The invention belongs to a medical appliance, in particular to an endoscope steady state display method which is to image the inside of a focus on a target surface of a charge-coupled device (CCD) by an imaging technique or the like and to use a generated video signal to display dynamic images by means of human machine interface control. The method comprises: an endoscope (1) with a CCD images a detected focus on a target surface of the CCD; a video signal output from the front end of the endoscope is subjected to sampling, maintenance, A / D conversion and is input into a digital signal processor (DSP) (4) to be processed; and images are displayed on a monitor through video output. The method is characterized in that the images displayed on the monitor by the DSP (4) through video output are synchronous focus images captured with the same vibrating frequency of the focus of a patient. The method has the advantages of reducing the pains in the patient during detection of the focus, quickly capturing clear images and reducing detection time.

Description

technical field [0001] The invention belongs to medical equipment, in particular to an endoscope steady-state display method for imaging the inside of a lesion on a target surface of a special CCD device by means of imaging technology, and the generated video signal is controlled by a man-machine interface to display dynamic images. Background technique [0002] The existing endoscopic display method is that the doctor scans the lesion of the patient through a special probe (miniature CCD camera containing lens and lighting equipment), and takes pictures and samples from different sides for the specific position of the lesion, and the received The optical signal is converted into an electrical signal, and the analog-to-digital conversion (A / D) is digitally sent to the computer for processing and processing. During operation, the specific situation reflected by the special probe can be displayed on the computer monitor in real time, and at the same time, the frame, thawing an...
