Description

Scanning module, scanning method, electronic shutter and camera device

Technical Field

The present invention relates to the field of imaging technologies, and in particular, to a scanning module, a scanning method, an electronic shutter, and an imaging apparatus.

Background

The PWM (Pulse Width Modulation) dimming mode has the advantages of high dimming precision, no color coordinate deviation, simple implementation, low cost, and the like. However, the PWM dimming mode has a drawback that when the mobile phone is used for photographing to see the screen of the display module, the scrolling bright and dark stripes can be seen, which is caused by the interference between the sampling frequency of the camera of the mobile phone and the PWM bright and dark variation frequency of the backlight.

The mobile phone photographing principle is as follows: the shot scenery passes through the lens, an optical image is projected on the sensor, then the optical image is converted into an electric signal, the electric signal is converted into a digital signal through analog-to-digital conversion, the digital signal is processed and then sent to a mobile phone processor for processing, and finally the digital signal is converted into an image which can be seen on a mobile phone screen. Electronic shutters of existing cameras are all unidirectional in scanning, and light sensing units can sense and record external optical signals and convert the optical signals into electric signals after being electrified. Due to the fact that the backlight is periodically changed in brightness by PWM driving of the backlight, when the PWM frequency is low, the brightness change can be identified by frame data captured by a camera of the mobile phone.
