Embodiment Construction

[0022] figure 1 It is a schematic diagram of the embodiment of the present invention. As shown in the figure, the module manufacturer first establishes a data storage system, which includes a test station, a database and a network shared hard disk. Regarding the storage space, it is stored in the form of a server. Store data in the form of a database. In theory, such a storage space can be expanded infinitely, and can continuously meet the different needs of different customers.

[0023] Each camera module has a unique fuse ID to identify different modules. When the module manufacturer produces, the test data and pictures (as mentioned above) generated by each camera module are named and stored on the server with the fuse ID. The storage speed of this method will also be faster. After the data is generated, it only needs to be saved to the server. It does not need to be burned to OTP / EEPROM, and the module will not be scrapped due to burning failure.

Abstract

The invention provides a novel modular individual parameter passing method. The novel modular individual parameter passing method comprises the following steps of: (1) reading a unique product ID of a modular product by using reading equipment; (2) determining corresponding modular individual parameters according to the product ID; and (3) passing modular individual parameters to a client by utilizing information transfer equipment. The defects that the traditional storage scheme is small in storage space, low in storage speed and small in data storage amount can be overcome, the requirements of high-end customers on the image quality are greatly met, the cost is reduced, and the product yield is improved.

Description

technical field [0001] The invention relates to a method for acquiring OTP data of a high-pixel module, in particular to a method and a system for transmitting personalized parameters of a novel module. Background technique [0002] At present, when camera module manufacturers produce camera modules, they generate some personalized parameters / data according to the characteristics of each module, such as module ID, Lens ID, motor ID, AWB, shading, and AF, etc., which require back-end system settings. For the data, the OTP / EERPOM scheme is currently used, that is, the data generated by each camera module is stored in the OTP / EERPOM. When the mobile phone uses the camera module, it first reads the data from OTP / EERPOM, and then applies it to the sensor. The purpose of this is to make a set of personalized parameters of each camera module read out by the back-end system, and perform targeted settings, which can greatly improve the consistency of the modules. The disadvantage i...
