Hereinafter, a socket for a camera module including a header board 220 and an upper module 230, and a camera module inspecting apparatus using the same will be described in detail.

8 is a block diagram illustrating a camera module inspection apparatus including a socket for a camera module according to some embodiments of the present invention.

Referring to FIG. 8, an apparatus for inspecting a camera module according to some embodiments of the present invention includes a socket 210 and a controller 240.

The socket 210 includes a header board 220 and an upper module 230.

Specifically, the header board 220 includes a camera module (CM), a signal conversion section (222), and a power signal section (224). The description of the camera module CM has been described in detail with reference to FIGS. 1 to 3 and will not be described here.

The signal converter 222 receives a control signal for controlling the socket from the controller 240 and converts the control signal to provide the image signal to the image switching converter 232 included in the upper module 230. At this time, the signal conversion unit 222 can receive the control signal through the general cable (including the copper wire), not the optical cable 260.

The power signal unit 224 may provide a power source for operating the camera module CM and a test signal for testing the camera module CM. At this time, the power supply and the test signal may be provided from the main computer 250 (250) through the controller 240. Likewise, the power signal portion 224 can receive the test signal and the power through a common cable (e.g., including a copper wire) rather than an optical cable 260.

The upper module 230 includes an image switching converter 232, an image processor 234, and an optical signal converter 236.

The image switching converter 232 may control the operation of the image processor 234. The image switching converter 232 can operate by receiving a signal from the signal converter 222 of the header board 220.

At this time, the image switching converter 232 may operate based on a Mobile Industry Processor Interface (MIPI) protocol. However, the present invention is not limited thereto.

The image processing unit 234 can process the image data received from the camera module CM. Specifically, the image processor 234 is controlled by the image switching converter 232, and can process the image data according to the MIPI protocol. For example, the image processing unit 234 may convert or compress raw data received from the camera module CM into data according to the MIPI protocol. However, the present invention is not limited thereto.

The optical signal converter 236 converts the image data processed by the image processor 234 into an optical signal. The optical signal converting unit 236 can transmit the converted image data to the controller 240 through the optical cable 260.

In the case of optical cable 260, it provides high reliability and high speed. For example, optical cable 260 provides a speed (or bandwidth) of about 1 Gbps or more (about 2 Gbps to about 3 Gbps) while a normal cable (e.g., a parallel cable including copper) provides about 1 Gbps of speed ). ≪ / RTI > In addition, due to the characteristics of the optical cable 260, it is resistant to distortion and deformation during signal transmission, and is not greatly affected by noise, thereby minimizing errors in data transmission.

The present invention can transmit a high capacity image data at a higher speed than an existing cable by using the optical cable 260. Accordingly, it is possible to shorten the time for transmitting the image data to the main computer 250, and reduce the inspection time for the camera module. Further, by using the optical cable 260 that is stronger in noise than the conventional cable and hardly distort the transmission signal, the accuracy and reliability of the inspection for the camera module can be enhanced.

The controller 240 includes an optical signal converting unit 242, an interface board 244, and a capture board 246.

The optical signal converting section 242 can convert the received optical signal into data that can be processed by a computer. For example, the optical signal converting unit 242 may convert the optical signal transmitted from the optical signal converting unit 236 of the socket 210 into image data. However, the present invention is not limited to this, and the optical signal converted by the optical signal converting unit 242 of the controller 240 may be converted into data that can be processed by the computer in the optical signal converting unit 236 of the socket 210 . That is, the optical signal converting unit 242 of the controller 240 and the optical signal converting unit 236 of the socket 210 can perform bidirectional communication with each other.

The interface board 244 exchanges data between the optical signal converting unit 242 and the capture board 246. In addition, the interface board 244 performs data exchange between the socket 210 and the capture board 246. For example, the interface board 244 may exchange data with the signal conversion unit 222 or the power signal unit 224 included in the header board 220 of the socket 210.

At this time, the interface board 244 can communicate with the socket 210 by using a general data cable (including a copper wire) instead of the optical cable 260. This is because, in the case of exchanging data between the interface board 244 and the socket 210, since a high-capacity image data is not included, a normal cable speed is sufficient. However, the present invention is not limited thereto.

The capture board 246 may control the socket based on commands received from the main computer 250. The capture board 246 can transmit the image data of the camera module CM received from the optical signal converting unit 242 to the main computer 250. [ Then, the capture board 246 may transmit a control signal to the socket 210 through the interface board 244. That is, the capture board 246 can receive an instruction from the main computer 250 and control the inspection process of the camera module CM.

Although not explicitly shown in the drawing, the capture board 246 and the main computer 250 may also communicate using a high-speed data cable, such as an optical cable. However, the present invention is not limited thereto.

The image switching converter 232 may control the operation of the image processor 234. At this time, the image switching converter 232 may directly receive the control signal from the controller 240 and control the image processor 234. [

The image processing unit 234 can process the image data received from the camera module CM. Specifically, the image processor 234 is controlled by the image switching converter 232, and can process the image data according to the MIPI protocol. However, the present invention is not limited thereto.

The optical signal converter 236 converts the image data processed by the image processor 234 into an optical signal. The optical signal converting unit 236 can transmit the converted image data to the controller 240 through the optical cable 260
