Problems solved by technology

Therefore, image sensors with rolling shutter exposure schemes are not suitable for shooting in motion or shooting objects in motion
At the same time, prolonging the exposure time will also increase the power consumption of the capsule endoscope.

Abstract

The invention provides a control method of a capsule endoscopy. The control method comprises the steps of controlling multiple rows of pixels in an image sensor to start integration at the same momentafter a row synchronizing signal is detected, controlling an illumination module to illuminate in an exposure time period, controlling multiple rows of the pixels to finish integration row by row, and finally, sequentially reading out integration data of each row of the pixels based on a finishing sequence of row-by-row integration of multiple rows of the pixels. According to the control method,multiple rows of the pixels in the image sensor are opened together and integrated at the same moment, so that compared with a scroll exposure control manner, the whole exposure period of the image sensor is shortened, and motion blur can be effectively avoided. The invention further relates to the capsule endoscopy controlled by virtue of the control method.

Description

technical field [0001] The present application relates to the technical field of medical devices, in particular to a method for controlling a capsule endoscope, and a capsule endoscope controlled by the method. Background technique [0002] Most of the existing capsule endoscopy products use the rolling shutter exposure scheme for image collection. See figure 1 The image sensor has multiple rows of pixels R1'-Rx', and the image sensor adopting the rolling shutter exposure scheme needs to be exposed row by row from R1'-Rx' multi-row pixels, and then end the exposure row by row, and based on the exposure The exposed data are transmitted sequentially in sequence. Specifically, after the line synchronization signal appears, the image sensor controls each pixel row to complete the reset in turn, and starts to expose row by row from the first row of pixels R1'. The level becomes high level, and the lighting work is turned on. Before the exposure data of the pixels in the first...
