Problems solved by technology

[0007] Since the exposure time of the detection units of the 0th line and the 15th line cannot overlap, the pixel data in the same picture will be obtained at different times, and the resulting picture will be skewed and distorted. When the scanning frequency is not high , this phenomenon is especially serious due to the large time difference between the acquisition time of the first and last rows of pixel data

Embodiment Construction

[0028] In this embodiment, the image pickup device and figure 1 The image pickup device in has the same circuit structure, but the way its exposure controller 11 controls the sensor array 12 and the light source 13 is different from the traditional one. Therefore, it will cooperate with figure 1 and image 3 Be explained.

[0029] see again figure 1 , the image pickup device in this embodiment includes an exposure controller 11 , a sensor array 12 and a light source 13 . The exposure controller 11 also has a vertical counter 111 and a horizontal counter 112 . The sensor array 12 is composed of a plurality of detection units (not shown) arranged in a matrix. The detection units continuously receive external light and accumulate corresponding charges. The light source 13 is used to irradiate the image to be detected, so that the image can generate light incident on the sensor array 12 to expose the detection unit.

[0030] The operation of the image pickup device in this em...

Abstract

The invention provides a kind of image picking device, which is used to detect image and generate the pixel data of the image. The device includes includes sensor, source and controller. The sensor has several detecting units, all the detecting units is exposed in its exposure time in order and generates pixel data, and all the exposure time is overlapping. The source illuminates the image and makes the image be detected by the sensor. The controller starts the source in the overlapping time of exposure time.

Description

technical field [0001] The present invention relates to an image pick-up device and its method, especially designed to obtain the pixel data in the same picture at the same time, so as to avoid the distortion of the picture when picking up dynamic images. Background technique [0002] figure 1 A circuit block diagram of an image pickup device is shown, which includes an exposure controller 11 , a sensor array 12 and a light source 13 . The exposure controller 11 also has a vertical counter 111 and a horizontal counter 112 . The sensor array 12 is composed of a plurality of detection units (not shown) arranged in a matrix. The detection units continuously receive external light and accumulate corresponding charges. The light source 13 is used to irradiate the image to be detected, so that the image can generate light incident on the sensor array 12 to expose the detection unit. [0003] figure 1 The operation of the image pickup device in is as follows. Taking the sensor...
