Embodiment approach
[0072] Such as Figure 1A As shown, according to an embodiment of the present invention, the control device based on defocus curve state detection of the present invention further includes: MIPI interface 5 , parameter sending module 6 and defocus curve sending module 7 . In this embodiment, the MIPI interface 5 and the image interpolation module 1 are electrically connected to each other. The pixel data generated outside the control device of the present invention is transmitted to the image interpolation module 1 through the MIPI interface 5, so as to realize the interpolation operation of the pixel data. The pixel data is received from the outside through the MIPI interface 5, which ensures that the interpolation module can continuously perform interpolation operations on the pixel data, and ensures the continuous and stable operation of the entire control device. In this embodiment, the parameter sending module 6 is electrically connected to the image interpolation module ...

Abstract
The invention relates to a defocusing curve state detection-based control apparatus and a system comprising the same. The control apparatus is realized based on an FPGA. The control apparatus comprises an image interpolation module used for receiving pixel data from outside and performing interpolation on the pixel data, an image extraction module used for performing Y component extraction on thepixel data subjected to the interpolation, a resolution power calculation module used for calculating the pixel data subjected to the Y component extraction to obtain an MTF value, and a control module used for controlling an external apparatus according to the MTF value. By embedding a hardware algorithm and the control module into the FPGA, the problems of pixel data transmission delay, algorithm delay and the like caused in command sending and data transmission processes of an upper computer in a conventional technology are avoided; and by utilizing good parallel and flow process characteristics of the FPGA, each frame of image is subjected to pixel data interpolation and MTF value calculation directly in a pixel data collection process, so that the working efficiency is improved.
Description
technical field [0001] The invention relates to a control device based on defocus curve state detection and a system containing the device. Background technique [0002] In the prior art, the test of the defocus curve is based on the host computer. First, in the initial state, the upper computer sends a command to drive the image sensor to expose, the image is generated by the image sensor and transmitted to the FPGA tooling board, then cached, and then transmitted to the PC and the PC calculates the MTF value of the current image. After the PC calculates the current MTF value, it sends a command to drive the motor, and then calculates the MTF of the next point until the entire curve is completed after the motor stops. During this process, the image sensor starts to transmit the image to the host computer and there will be a delay of several frames before the current frame is completely received. At the same time, the host computer first caches the received image, and then...
