Image processing apparatus

摘要

Provided is an image processing apparatus which can easily perform focus adjustment only by switching a program in accordance with a kind of an inspection object. The image processing apparatus according to the invention includes: an imaging unit for imaging a region including an inspection object; a focus adjustment mechanism; and a control unit for controlling a operation of the focus adjustment mechanism. A plurality of pieces of inspection condition data are set, the data being made up of a plurality of setting items including a focus position data. When the switching instruction from one inspection condition data to another inspection condition data is accepted, the operation of the focus adjustment mechanism is controlled based on focus position data included in another inspection condition data after switching.

1. An image processing sensor, comprising:
an imaging unit for acquiring a first image of a region including an inspection object; a focus adjustment mechanism for adjusting a focus position of the imaging unit on the inspection object; an image processing unit for executing image processing with the first image acquired by the imaging unit; an inspection condition data setting portion for setting a plurality of pieces of inspection condition data concerning a condition for inspecting the inspection object, each of the plurality of pieces of inspection condition data comprising a plurality of setting items including parameters used for image processing to be executed by the image processing unit and focus position data concerning an operation of the focus adjustment mechanism; a memory for storing the plurality of pieces of inspection condition data set by the inspection condition data setting portion; a control unit for controlling the operation of the focus adjustment mechanism based on focus position data included in a selected inspection condition data from the plurality of pieces of inspection condition data and for outputting an inspection result based on image processing with parameters included in the selected inspection condition data from the plurality of pieces of inspection condition data; and, an inspection condition switching instruction accepting portion for accepting a switching instruction for switching the selected inspection condition data to another inspection condition data to be selected; whereby, when the switching instruction is accepted by the inspection condition switching instruction accepting portion, the control unit controls the operation of the focus adjustment mechanism based on focus position data included in said another inspection condition data read from the memory and the image processing unit receives a second image acquired by the imaging unit based on the focus position data included in said another inspection condition data and executes image processing with the second image based on parameters included in said another inspection condition data read from the memory.
