Embodiment Construction

[0030] Figure 1a It is a schematic diagram of an optical center monitoring device according to an embodiment of the present invention. The optical center monitoring device 100 corresponds to a lens 102 to calculate an optical center on a sensor array 104 . The optical center monitoring device 100 includes a monitoring component 101 and a processing unit 106 . It is worth mentioning that the lens 102 and the sensor array 104 can further serve as an image pickup component for the optical center monitoring device 100 to generate digital image data corresponding to a target object.

[0031] In one embodiment, the monitoring component 101 has a base (not shown) for disposing the lens 102 and the sensor array 104 , and providing necessary electrical connection and signal processing with the sensor array 104 . The base may have an adjustment function for the user to selectively align the lens 102 with the sensor array 104 according to the results of the optical center monitoring de...

Abstract

The invention is an optical center monitoring device and method for corresponding to a lens to calculate an optical center of a sensor array. The sensor array comprises a plurality of sensing cells. The optical center monitoring device comprises a monitoring component and a processing unit, where the monitoring component is used to arrange the lens and the sensor array. When a testing light comes to the lens, the sensor array makes each sensing cell separately obtain a sensed value by detecting the quantity of the testing light. The processing unit is connected with the sensor array through the monitoring component to select a plurality of sensing cells with a certain sensed value each so as to calculate the optical center.

Description

technical field [0001] The invention relates to an optical center monitoring device and method. More particularly, the present invention relates to an optical center monitoring device and method applied to a digital image forming system. Background technique [0002] Digital cameras have transformed from expensive professional equipment to popular consumer products. Its principle is to use a lens to project an image onto a sensor of a digital camera, such as a Charge Coupled Device (CCD for short). Through the charge-coupled device, the light signal collected by the camera lens is converted into a digital image signal, and then processed by the electronic circuit, the digital image signal is stored in the memory. [0003] The image sensor is usually in the form of an array, from the earliest 320×240, 640×480, 1280×960, until now the mainstream 2048×1536 in the market. Therefore, with the continuous advancement of sensors, digital cameras have gradually occupied a place in...
