Embodiment Construction
[0018] In order to make the object, technical solution and advantages of the present invention clearer, 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.
[0019] In the embodiment of the present invention, the TV signal is processed by the camera module chip, so that the camera module chip combines the odd field signal data and the even field signal data to form a complete frame of data, and detects whether the spliced data is consistent with The original data is completely consistent to complete the verification of its parity field function, which greatly simplifies the verification process of the camera module chip and improves the verification efficiency.

The invention relates to the technical field of chip testing, and provides a method and device for chip verification. The method for chip verification includes the steps: S1, obtaining first signals, wherein the first signals comprise digital odd field television signals and digital even field television signals; S2, sending the first signals to a camera shooting module chip, S3, stitching odd field data and even field data of the first signals through the camera shooting module chip, generating second signals, S4, displaying the second signals to judge whether the second signals are in accord with the first signals or not, verifying whether the function of the camera shooting module chip is proper if the second signals are in accord with the first signals, and S5, verifying whether the function of the camera shooting module chip is wrong if the second signals are not in accord with the first signals. According to the method and device for chip verification, the television signals are processed by the camera shooting module chip, the odd field signal data and the even field signal data of the television signals are stitched into frame complete data through the camera shooting module chip, whether the stitched data are in full accord with the original data is confirmed, the functions of odd-and-even fields are verified, therefore, the verification procedures of the camera shooting module chip are simplified greatly, and verification efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of chip testing, and in particular relates to a chip verification method and device. Background technique [0002] The scanning method of the camera is divided into progressive scanning and interlaced scanning, and the above-mentioned scanning methods are methods for representing moving images on a display device. For interlaced scanning, it divides each frame into two fields, and each field contains all the odd or even lines in the frame. Usually, the odd lines are scanned first to obtain the first field, and then the even lines are scanned to obtain the second field. two games. [0003] Existing camera module chips usually have an odd-even field mosaic function, which is used to fuse the odd-even field signal data collected by the camera through scanning into one frame of data. Make sure it functions correctly so that data is collected correctly. At present, the verification method for the odd-even fiel...
