As shown in FIG. 4, it is configured to record an image of a printed circuit board 21 to be inspected using a television camera 22, and to judge the quality of the mounting based on the recorded image. Note that the reference numeral 24 in the figure is an image check device, and the reference numeral 25 is a control circuit. Generally, with this type of television camera 22, only objects with a shallow depth and whose depth of field does not pose a problem are inspected. This is because the depth of focus of the imaging lens is shallow, and the structure is not such that it is possible to simultaneously focus on the front and rear parts of a deep subject.

できるようにすることを技術課題とする。[Problem to be Solved by the Invention] For this reason, it is necessary to simultaneously record images of character patterns printed on the molded surface of an integrated circuit (IC) and the lead wires of the integrated circuit, where depth of field is a problem. It was not possible to inspect it. When you focus on a character pattern,
This is because the lead wires of the integrated circuit cannot be brought into focus, so accurate image recognition cannot be performed, and conversely, when the lead wires are brought into focus, the character pattern cannot be accurately recognized as an image. For this reason, in the prior art, this type of inspection could only be done manually. The present invention has been made in view of the above circumstances, and it is an object of the present invention to record a single still image that is in focus over the entire depth of field when recording an image of a subject with depth using a television camera or the like. The technical challenge is to be able to perform the above-mentioned mounting inspections and component inspections without human intervention.

れる。[Operation] In the present invention, the optical distance between the imaging lens 3 and the photoreceptor 5 is relatively displaced at least within the range of the imaging focal depth L. The photoreceptor 5 has an imaging focal depth L
An image of the subject J with depth is projected continuously or intermittently over the entire range. At this time, as shown in FIG. 2, for example, if we focus on a point Q on the subject J, the projected image (hereinafter referred to as a pixel) of the point Q will have an imaging focal depth L
At a position L0 within the range, a focused point image q is recorded on the photoreceptor, and at other positions, an image spread out into a blurred circle around the point image q is superimposed and recorded. That is, a focused point image q and an image of a circle of confusion r spreading around it are recorded as latent images on the photoreceptor.

なる。By the way, as is clear from FIG. 2, the focused point image q has the highest optical energy density and is more strongly recorded on the photoreceptor than the image of the circle of confusion r, which has a weaker optical energy density. In other words, the image of the expanding circle of confusion r becomes unclear, and the point image q is clearly recorded as a pixel on the photoreceptor. Furthermore, when paying attention to other points of the subject J, the same thing as above can be said. Therefore, when an image of a deep subject J is continuously or intermittently projected over the entire range of the imaging focal depth L, the entire image of the deep subject J is projected onto the photoreceptor 5, with a depth of field K The entire range of the image will be recorded as a still image that is in focus.

By controlling the current flowing through the electromagnetic coil 8a with the excitation controller 10, the coil bobbin 8 is moved forward and backward with a required amplitude stroke, and the photoreceptor 5 is moved at least to the imaging focal depth L.
It is configured to vibrate in the optical axis direction over a range of . Incidentally, in this embodiment, as the excitation controller 10, an oscillator that outputs a sinusoidal or triangular waveform pulse current is used, and the scanning speed for extracting pixel signals of the photoreceptor (CCD) 5 is matched with the frequency of the coil bobbin 8. Therefore, the coil bobbin 8 is configured to be adjustable so that its frequency is approximately 30 Hz and its amplitude stroke is within a range of at least the imaging focal depth L (approximately 1 to 2 mm). That is, as shown in FIG. 1, at the position L1 where the photoconductor 5 has advanced the most, the deepest point J1 of the subject J is in focus, and the photoconductor 5
At the position L2 where the subject J is the most retreated, the shallowest point J2 of the subject J is in focus.

出しが可能だからである。On the other hand, each time the photoreceptor 5 is vibrated one stroke over at least the range of the imaging focal depth L, the amount of charge accumulated in each photoelectric conversion element of the photoreceptor 5 during that period is chronologically recorded as a pixel signal. It is configured to output. That is, in each photoelectric conversion element of the photoreceptor 5, the amount of charge of the focused point image q and the amount of charge of the image of the circle of confusion with radius r extending around it are the amount of charge for one pixel. It is accumulated as The focused point image q has the highest optical energy density, and a larger amount of charge is accumulated than the image of the circle of confusion, which has a weaker optical energy density. In other words, only the in-focus point image q is recorded as a pixel in each photoelectric conversion element. Note that the shutter device is not necessarily required in this embodiment. This is because the recorded image data can be saved, erased, and recalled by operating appropriate switches.

Instead of outputting a pixel signal in time series for each stroke, if the subject is stationary, it is also possible to output a pixel signal for each stroke. (2) The present invention is also applicable to general cameras, and in that case, a general photosensitive film can be used instead of the CCD type photoelectric conversion element for the photoreceptor 5.
