Embodiment Construction

[0043] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0044] Such as figure 1 As shown, in one embodiment, a method for data processing is proposed, which is applied to a mobile terminal equipped with a camera, and specifically includes the following steps:

[0045] Step S102: Read camera module calibration data from the one-time programmable memory OTP.

[0046] Specifically, the camera module calibration data is an adjustment parameter set for the camera device, and the camera module calibration data may include at least one of the following: the ratio R / G of the red value to the green value, the ratio B / G of the blue value to the green value G...

Abstract

The invention provides a data processing method. The data processing method comprises steps that shooting module group calibration data is read from a One Time Programmable memory OTP; the shooting module group calibration data is encrypted; the encrypted shooting module group calibration data is stored as a system file. The camera data is stored as the system file, and problems of a prior art such as low camera development and debugging efficiency and inconvenient analysis and solution of shooting quality problems are solved, and therefore a camera development period is shortened, and efficiency of analyzing and solving the shooting quality problems is improved. The invention also provides a data processing device.

Description

technical field [0001] The present invention relates to the field of camera technology, in particular to a data processing method and device. Background technique [0002] As 5M (mega), 8M, 12M and other high-pixel cameras are more and more widely used in mobile terminals, mobile terminal users have higher and higher requirements for the imaging effect and quality of mobile terminal cameras. In order to improve the camera module Consistency and performance in all aspects, OTP (One Time Programmable, one-time programming) technology is widely used in camera modules. [0003] In the prior art, when there is a problem with the camera of the mobile terminal, the mobile terminal can obtain effective information from the OTP memory in order to analyze the background and cause of the problem. The current practice is usually from NVM (Nonvolatile Memory, non-volatile The OTP data obtained in the lost memory) is directly handed over to the ISP (Image Signal Processor, Image Signal P...
