Image treatment method

Abstract

There provides an image processing method with which the sharp image of an object moving two-dimensionally can be obtained in a short period of time even when the image is picked up by an imaging apparatus comprising an interlaced scanning type imaging device. The method for processing an image picked up by an imaging apparatus 10 comprising an interlaced scanning type imaging device 13, wherein image signals of even-numbered fields outputted from the imaging apparatus 10 are generated from image signals of upper and lower horizontal lines (1, 3), (3, 5) of odd-numbered fields holding horizontal lines (2, 4) of each of the even-numbered field therebetween, and the generated respective image signals are set as image signals of the even-numbered field.

Description

technical field [0001] The present invention relates to such an image processing method, which is suitable for alleviating the blurring of images captured by an interlaced scanning system, especially the image blurring of objects moving in the horizontal direction. Background technique [0002] In recent years, systems that inspect the electrical characteristics of electronic components during the manufacturing process, compile a database of the inspection results for each component, and manage them during the distribution process have become popular. For example, a system has been developed that uses a digital camera to photograph the product identification number attached to the surface of the semiconductor in pre-shipment inspection of manufactured semiconductors, performs character recognition processing on the photographed image signal, converts it into character data, and Semiconductor test results are linked and stored in the database of the server for management. ...

Problems solved by technology

However, since the imaging device of the interlaced scanning method alternately outputs the image signals of the odd field and the even field every 1 / 60 second, there is a time deviation of 1 / 60 second between the odd field image and the even field image.

Therefore, in the case of a subject moving in the horizontal direction relative to the imaging device ( Figure 8 (B)), relying only on increasing the electronic shutter speed (shortening the exposure time), cannot prevent image deviation between odd and even fields, and cannot obtain a clear image ( Figure 8 (B))

[0007] In addition, in the method of processing the image signal captured by the interlaced imaging device using the conventional image processing method, there is a problem that the burden of the processing method is heavy and the processing time is too long.
