Abstract
A particle image analyzer provided with an image processor for executing predetermined image processes on a particle image containing an image of a particle, a reading means for reading test result data from a flash memory card on which are previously recorded test result data equivalent to the processing result of the image processor during normal operation, and a testing means for determining whether or not the image processor is operating normally by comparing the processing result obtained when the test image is used in the image processor, and test result data read from the flash memory card by the reading means.
Claims22
A method for analyzing a particle contained in a liquid comprising steps of:
- controlling, by a processor, an image processing circuit so as to execute a predetermined image process on a test image which contains a test particle image;
- comparing, by the processor an image processing result of the test image by the image processing circuit with a predetermined test image processing result;
- determining, by the processor, whether or not the image processing circuit is functioning normally based on the comparing result;
- imaging a particle contained in a liquid passing through a flow cell by an imaging part, when it has been determined that the image processing circuit is functioning normally;
- obtaining, by the processor, feature information representing feature of a particle image contained in an image obtained by the imaging part, by controlling the image processing circuit so as to execute the predetermined image process on the image obtained by the imaging part;
- and
- displaying, on a display, information indicating that the image processing circuit is not functioning normally, when it has been determined that the image processing circuit is not functioning normally.
A particle analyzer for analyzing a particle contained in a liquid comprising:
- a flow cell for passing a liquid containing a particle;
- an imaging part for imaging the particle contained in the liquid passing through the flow cell;
- an image processing circuit for executing a predetermined image process on a an image containing a particle image;
- a controller for controlling the image processing circuit so as to execute the predetermined image process on a test image containing a test particle image, comparing an image processing result of the test image by the image processing circuit with a predetermined test image processing result, and determining whether or not the image processing circuit is functioning normally based on the comparing result;
- and
- a display device;
- wherein the controller controls the imaging part so as to image the particle contained in the liquid passing through the flow cell, when the controller has determined that the image processing circuit is functioning normally, and obtains feature information representing feature of a particle image contained in an image obtained by the imaging part by controlling the image processing circuit so as to execute the predetermined image process on the image obtained by the imaging part;
- and
- wherein the display device displays information indicating that the image processing circuit is not functioning normally when the controller has determined that the image processing circuit is not functioning normally.
A computer readable storage medium for storing a computer program for analyzing, on a computer, a particle contained liquid wherein
- the computer program comprises software instructions for enabling the computer to perform predetermined operations, comprising:
- controlling an image processing circuit so as to execute a predetermined image process on a test image containing a test particle image;
- reading, from a memory, a predetermined test image processing result recorded beforehand on the memory;
- comparing the test processing result read from the memory with an image processing result obtained by executing the predetermined image process on the test image;
- determining whether or not the image processing circuit is functioning normally based on the comparing result;
- controlling an imaging part so as to image a particle contained in a liquid passing through a flow cell, when it has been determined that the image processing circuit is functioning normally;
- obtaining feature information representing feature of a particle image contained in an image obtained by the imaging part, by controlling the image processing circuit so as to execute the predetermined image process on the image obtained by the imaging part;
- and
- controlling a display so as to display information indicating that the image processing circuit is not functioning normally, when it has been determined that the image processing circuit is not functioning normally.
