Image data generation method and element installation apparatus using the same

Abstract

The present invention provides an image data forming method of generating high resolution image data by a technique of pixel staggering without preparing an additional optical moving mechanism within an imaging apparatus, and a components mounting apparatus using it. In the case of a fine sized component insufficient in recognition at image pick-up in standard resolution (S1 is NO), first, the image pick-up is performed at a reference position (S4); next, a loading head 36 is moved in X direction and Y direction by a half resolution from the reference position (S5). When a size of 1 pixel of imaging device 74 is 7 [mu]m*7 [mu]m, a moving amount F toward X axis and Y axis of the loading head 36 corresponding to 25 [mu]m of the half resolution is 25 [mu]m, and it can be solved by a fine moving function prepared in the loading head 36 originally. High fine image data can be obtained by the technique of pixel staggering in such a way that an image shifted in X axis direction and Y axis direction by the half resolution is picturized (S6), and that the image data of the 2 kinds are composed (S7).

Description

technical field [0001] The present invention relates to an image data generation method for generating image data with a resolution higher than the actual resolution of an imaging element, and a component mounting apparatus using the method. Background technique [0002] In the past, there have been substrate supply devices and distributors on the upstream side of the production line, which constitute the production line together with the reflow furnace on the downstream side of the production line, and electronic components (hereinafter, simply referred to as components) are automatically mounted on the equipment that is fed into the own device. Printed circuit boards (hereinafter simply referred to as substrates), and electronic component mounting devices (hereinafter simply referred to as component mounting devices) for producing substrate units. [0003] Usually, this kind of component mounting device has a monitoring input device composed of a CRT or liquid crystal disp...

Problems solved by technology

[0025] However, if Figure 8 As shown, in the digital camera for component recognition (including still camera, video camera) used by the component mounting device, spatial pixel shift is performed in order to achieve high resolution. Therefore, in the imaging device, it is necessary to New mechanism for moving the optical axis for 1 / 2 pixel shift

Therefore, the price increase of the component mounting device caused by the addition of such a mechanism for moving the optical axis is unavoidable, which is unsatisfactory.
