Abstract: An electronic viewer for peephole contains an image capture unit for shooting images; a main circuit board including an application specific integrated circuit electrically connected with the image capture unit so as to control the image capture unit to shoot the images; a flat panel display unit electrically connected with the main circuit board so as to display the images shot by the image capture unit; an ambient light sensor electrically coupled with the main circuit board so as to sense a change of an ambient light source. Thereby, when the ambient light source changes, an electronic viewer is driven to operate the application specific integrated circuit, and the application specific integrated circuit controls the image capture unit to shoot the images so that the flat panel display unit displays the images.

Abstract: The present invention discloses a digital peephole viewer device, which integrates with a door lens assembly on a door board to acquire optical images captured by the door lens assembly, converts the optical images into digital images, and then presents the digital images. The digital peephole viewer device of the present invention comprises a housing, an image capture unit, a signal processing unit, a display unit and a connection means. The image capture unit has a first lens to receive the optical images captured by the door lens assembly. The signal processing unit converts the optical images into continuous dynamic digital images. The display unit presents the continuous dynamic digital images. The connection means integrates the housing with the door lens assembly.
