Abstract:
1. A sensing range selectable image sensor module, comprising: a lens comprising a first light-sensing area and a second light-sensing area, the amount of light passable through said first light-sensing area being larger than the amount of light passable through said second light-sensing area; two sensors arranged at one same side relative to said lens and adapted for receiving light through said first light-sensing area and said second light-sensing area respectively to generate a respective trigger signal; and a controller electrically coupled with said two sensors and selectively controlled to receive the trigger signal generated by one of said two sensors; wherein said first light-sensing area is formed of three spaced first transparent blocks and said second light-sensing area is formed of two spaced second transparent blocks; the distance between said two second transparent blocks is shorter than the distance between each two adjacent ones of said first transparent blocks.
