Image scanning apparatus, and method and apparatus for controlling receiving of image scanning optical signal

A method for controlling receiving of an image scanning optical signal, comprising:

• sending a control signal to an array photosensitive pixel unit, wherein the control signal is used for controlling the array photosensitive pixel unit to receive at least one optical signal;
• wherein sending the control signal to the array photosensitive pixel unit comprises:
• when a light source gives out lights, receiving a first control pulse signal from the light source;
• and sending the first control pulse signal to the array photosensitive pixel unit, so as to control at least one photosensitive pixel point of the array photosensitive pixel unit to receive the at least one optical signal of an image reflected under the light source and not to receive any optical signal of external stray lights;
• when the light source does not give out the lights, receiving a second control pulse signal from the light source;
• and sending the second control pulse signal to the array photosensitive pixel unit, so as to control the at least one photosensitive pixel point of the array photosensitive pixel unit to stop receiving the at least one optical signal.

An apparatus for controlling receiving of an image scanning optical signal, comprising:

• a sending component, configured to send a control signal to an array photosensitive pixel unit, wherein the control signal is used for controlling the array photosensitive pixel unit to receive at least one optical signal;
• wherein the sending component comprises:
• a first receiving element, configured to, when a light source gives out lights, receive a first control pulse signal from the light source;
• and a first sending element, configured to send the first control pulse signal to the array photosensitive pixel unit, so as to control at least one photosensitive pixel point of the array photosensitive pixel unit to receive the at least one optical signal of an image reflected under the light source and not to receive any optical signal of external stray lights;
• a second receiving element, configured to, when the light source does not give out the lights, receive a second control pulse signal from the light source;
• and a second sending element, configured to send the second control pulse signal to the array photosensitive pixel unit, so as to control the at least one photosensitive pixel point of the array photosensitive pixel unit to stop receiving the at least one optical signal.
