- the circuit printed (34) is itself connected, according to the invention, to a data processing not shown, via a connector (34), comprising a memory, making it possible to store the data contained in the light beam reflected by the products (1) to be counted, and a microprocessor, allowing data processing to be carried out. All the elements making up the CIS module (3) are contained in a housing (30) provided with a window (36) permeable to light waves.
- CIS module rather than the complex system used in the prior art makes it possible to reduce the dimensions of the counting device, while maintaining good resolution (of the order of 600 dpi or more). In addition, it reduces strongly the duration of the measurement (less than 2 seconds), because the module covers the entire length of the tray.
- a single CIS module (3) or several CIS modules (3 1 , 3 2 , 3 3 ) can be arranged above the tray. If several CIS modules (3 1 , 3 2 , 3 3 ) are used, these modules can be arranged, either in series, or in such a way that the lighting and reading zones of the reflected beam of two adjacent CIS modules overlap. (4), as in Figures 1 and 2.

- the back-and-forth movement is triggered by the depressing of a push button, touch screen, keyboard or any other equivalent means, not shown, arranged for example on the top of the cover of the counting device according to the invention, so as to make the tray move back and forth.
- the counting device according to the invention is equipped with several CIS modules (3 1 , 3 2 , 3 3 ) whose reading zones of the reflected beam overlap (4), a calibration of the CIS modules must be carried out during the manufacture and / or maintenance of the counting device, so as to define the reading areas to be used for each CIS module.
- the calibration process requires the installation of a strip black (n) instead of a batch of products.
- White strips (b) are added on this black band (b) at the approximate location of the zones lighting overlapped by two adjacent CIS modules.
- the module calibration process begins with the reading (510) of the beam reflected by the different CIS modules. Then the leftmost module (3 1 ) is defined (511) as the current module. The first pixel of the module in progress is then stored (512) as the start (d 1 ) of the reading area to be used for said CIS module (3 1 ), in a table of beginnings of reading areas.
- the module calibration process continues with the search (513) for a transition position between the middle (m 1 , m 2 , m 3 ) of the module in progress and the end of the module in progress. This transition position corresponds to the middle of the white band (b). If the white band is not found, the counting device according to the invention leaves the calibration process by indicating (514) that a calibration error has occurred. If the white strip has been found, the transition position is stored (515) as the end (f 1 , f 2 ) of the reading area to be used for the current CIS module (3 1 , 3 2 ), in a table of end of reading areas.
- the next module is then defined (516) as the current module.
- the module calibration process continues with the search (517) for the transition position (middle of the white strip (b)) between the start of the current module and the middle (m 1 , m 2 , m 3 ) of the current module. If the white band is not found, the counting device according to the invention leaves the calibration process by indicating (518) that a calibration error has occurred. If the white strip has been found, the transition position is memorized (519) as the start (d 2 , d 3 ) of the reading zone to be used for the current CIS module (3 2 , 3 3 ), in the table of beginnings of reading areas.
- the last pixel of said module is stored as the end (f 3 ) of the reading area for this said module (3 3 ), in the table of end of reading areas.
- CIS module (3 1 , 3 2 ) corresponds to the start (d 2 , d 3 ) of the reading area to be used for the second, respectively third, CIS module (3 2 , 3 3 ).
- Each of the search steps (513, 517) of the position of transition begins with a definition (610) of the start of the search area (from the beginning to the middle of the module or from the middle to the end of the module) like the current pixel. Then, if the value of the current pixel is greater than a value setpoint, the current pixel is defined (611) as the left edge of the white strip (b). Otherwise, the next pixel is defined (612) as a pixel in Classes. If this pixel corresponds to the end of the search area, the search device counting according to the invention leaves the search process (513, 517) of the transition position by indicating (613) that a search error has occurred produced. Otherwise, the value of this pixel is in turn examined in relation to the setpoint.
- the counting device leaves the search process (513, 517) from the position of transition indicating (616) that a search error has occurred. Otherwise, the value of this pixel is in turn examined against the value setpoint.

- the CIS modules (3; 3 1 , 3 2 , 3 3 ) carry out, during a forward movement, for example around fifty scans, carried out alternately from left to right and from right to left and during the return movement, for example another fifty alternating scans.
- the light signal recorded by the photosensitive elements of the CIS circuits (33) consists of a sinusoidal signal whose vertices represent approximately the mediums of the products, the valleys represent the edges, and the distance separating two valleys corresponds to the thickness of a product to be counted.

- the counting process implemented by the counting device according to the invention, is shown in Figure 9. It begins when the push button is pressed by the user (910). The process then consists to carry out the processing (911) of a line, then to carry out a test (912) to find out if a certain number of lines, for example 100, has been scanned. If not, the result is stored (913), then a test (914) is performed to determine if the determined number of linear scans has been made. If yes, the test (914) is carried out directly, without storage (913) of the result. If the determined number of scans has not been performed, the program processes (911) the next line. Otherwise, the process continues with processing (915) results, then by posting (916) a report.
- a test (917) is carried out to determine whether there is a need for a next cycle. In the negative, the test (917) is carried out again to determine whether there is reason to proceed to a next cycle. If so, that is, if the device according to the invention detects that the push button has been pressed again, the process starts again from step (910).
- the processing step (911) of a line corresponds to the succession steps shown in Figure 10.
- the processing step (911) of a line begins with a step reversing the scanning direction (9110) and continues with a test step (9111) on determining the meaning.
- the line is memorized in step (9112) and in the case of a scan from right to left, the line is stored in step (9113).
- steps (9112, 9113) are followed, if the counting device according to the invention is equipped with several CIS modules, a concatenation step (9114) images read by the different CIS modules.
- the processing stage (911) of a line is continued, successively, by a search step (9115) the edges of the tray, by a pre-treatment step (9116) of the data, through a product analysis and accounting step (9117) (1) to count, and by a step of displaying the results (9118).
- the image concatenation step (9114) is shown in the figure 11. It makes it possible to avoid overlapping of the images by taking counts the reading areas defined for each CIS module during the module calibration process.
- the image concatenation step (9114) begins with a definition (91140) of the leftmost module as the current module, then with a definition (91141) of the first pixel of the image to be reconstituted as the current pixel of said image picture.
- the start of the reading area (d 1 , d 2 , d 3 ) to be used is then defined (91142) as the current pixel of the module (3 1 , 3 2 , 3 3 ).
- the current pixel of the module is defined (91143) as the current pixel of the image.
- the current pixel of the image is incremented (91144).
- a test (91145) is then carried out to determine whether the current pixel corresponds to the end of the reading area (f 1 , f 2 , f 3 ) to be used. If not, the module's pixel is incremented (91146), a step followed by the step of defining (91143) the current pixel of the module as the current pixel of the image. If so, a test (91147) is performed to determine if the module in progress is the last module. If not, the module is incremented (91148), step followed by the definition step (91142) of the start of the reading area (d 1 , d 2 , d 3 ) to be used as the module's current pixel (3 1 , 3 2 , 3 3 ). If not, the concatenation step ends.
- the search step (9115) of the edges of the tray (2) is represented in FIG. 12. This search step is carried out twice, a first time to determine the leftmost edge of the tray, a second time to determine the rightmost edge of the tray.
- the edge search step (9115) begins with a step of definition (91150) of the first (resp. last) pixel of the stored line as the current pixel of the image. This stage is followed by a stage of definition (91151) of the value of the current pixel as a reference value.
- This information consists of an 8-bit word representative of one of the 256 brightness levels received by the photosensitive element of the CIS module corresponding to the memory word processed.
- a stage of local vertex search (91152), which continues with a calculation step (91153) of the difference between the local level and the reference value memorized in step (91151).
- the search step (9115) of the edges is continues with a test step (91154) to determine if this difference is greater than a setpoint. If so, an edge has been found and the position of the corresponding pixel is stored (91155).
- the edge search step (9115) continues with the step of storage (91156) of the current pixel as a reference pixel. At this step succeeds test step (91157) to determine if it is the end (resp. from the beginning) of a line. If not, the research step (9115) of edges continues with the search step (91152) of local vertex. If so, the device memorizes (91158) that the edge has not been find.
- the setpoint of step (91154) generally corresponds to the difference in brightness levels which separates on average a vertex of a valley and, as can be seen in the diagram in Figure 8, the edge search step (9115) makes it possible to detect as an edge the vertex ys0 then, as we will see later, when processing the valley, noticing that the difference in brightness levels d1 between the summit and the next valley is less than another setpoint and that the percentage of vertex variation is greater than a value determined, it considers that it is not the edge of the tray and detects the next vertex ys1 as being the effective edge of the tray.
- the preprocessing step (9116) of the data, represented on the Figure 13 is not a compulsory step in the counting process according to the invention. It allows to average a determined number of lines for decrease background noise and / or auto-correlate image to enhance shape of the signal.
- the pre-treatment step (9116) begins with a step (91160) initialization at zero of the index n, which is carried out at the start of the cycle (910, figure 9), and storage in each of the X memories buffer of the line being processed.
- the pre-treatment stage (9116) continues with a test (91161) to determine, depending on the configuration of the counting device, if the use of averaging is appropriate. In if not, the pre-processing step (9116) continues with a test (91162) to determine, depending on the configuration of the counting device, whether the use of auto-correlation is appropriate.
- the preprocessing step (9116) continues with the storage (911611) in the buffer memory n associated with the line in course, from the line being processed, then by incrementing (911612) of the buffer index.
- the pre-treatment stage (9116) is continues with a test (911613) to determine if the memory index current buffer (n) exceeds the number of lines to average (X). In if so, the current buffer index is reset to zero (911614), then the current line is calculated (911615) in pixel averaging per pixel on all the lines (X) stored in the X buffer memories. If not, the pre-processing step (9116) continues directly by the calculation step (911615).
- the next step is a test (91162) for determine, depending on the configuration of the counting device, whether the use an autocorrelation is appropriate. If not, the pre-treatment stage (9116) ends (91163). If yes, the pre-treatment stage (9116) continues with a definition (911621) of the left edge of the tray as a current pixel, then by the autocorrelation calculation (911622) of the current pixel. The current pixel is then incremented (911623), then a test (911624) is performed to determine if the pixel in course corresponds to the right edge of the tray. If so, the pre-treatment (9116) ends (91163). If not, the current pixel is calculated (911622) using the autocorrelation formula in Figure 13.
- the product analysis and accounting step (9117) (1) between the edges is shown in Figure 14. It begins with a step of reading (91170) of a pixel to continue with a test step (91171) on the type of sequence. This test is carried out by determining whether the difference between the pixel being processed and the previous pixel is positive or negative and, if it is positive, starts the process of "local vertex” processing and if it is negative triggers the "local valley” treatment process.
- the "local summit” treatment process begins with a step of measure (91172) of the distance (dss) between vertices and continues with a test step (911721) to determine if this distance (dss) is greater at a minimum distance. If not, the processing process "local vertex” continues with a processing step of the next pixel and by the test (91171) on the type of sequence. If so, the process "local vertex” processing continues with a step of calculating (911722) the percentage of variation of the vertices: (ys2 - ys1) x 100 / ys1. If this variation is greater than a set value, the treatment process "local summit” continues with a test step (911723) to determine if the variation is negative.
- the treatment process "local vertex" continues with the reading step (91170) of a pixel. If the variation is positive, the "local summit” treatment process continues by a test step (911724) consisting in reading the content of the counter of the number of products and to determine if the content of this counter is less to 3. If the answer is negative, the "local summit” processing process ends. continues with the reading step (91170) of a pixel. If the answer is affirmative, the program continues with a registration step (911725) of the edge, considering that the treated vertex is actually the true edge of the tray.
- the "local top” processing process detected ys0 and that then, by detecting ys1, he finds that the variation for ys1 is greater than the set value and then, checking that the number of products is less than 3, it considers that ys1 is the real edge of the set of products to be counted. If the variation is less than the setpoint, the "local top” processing process validates (911726) the top in incrementing a counter which counts the vertices.
- This validation step (911726) of a vertex is followed by a jump to the local valley sequencer by returning the analysis and accounting (9117) of the products before the test step (91171) on the type sequence, to process a local valley according to the processing process "local valley” below.
- This "local valley” treatment always begins with the test (91171) on the type of sequence and then continues with a measurement step (91173) of the summit-valley distance (dsv) and the valley-valley distance (DOV). This step is followed by a test step (911731) to determine if the two distances (dsv, dvv) are correct with respect to values of reference. If not, the "local valley” treatment process is continues with the processing of the next pixel and the test step (91171) on the sequence type. If so, if the distances are correct the "local valley” treatment process continues with a step of validation (911732) of the valley, which consists in incrementing a counter of valley. This step is followed by a jump to the local vertex sequencer in returning the analysis and accounting step (9117) of the products before the test step (91171) on the type of sequence, to process a local vertex according to the "local summit” processing process.
- the counting method according to the invention comprises a processing step (915, FIG. 9) of the results, after the microprocessor of the counting device according to the invention has determined that it was an end-of-cycle step (914, Figure 9).
- the stage of processing (915) of the results is represented in FIG. 12. It starts with sorting (9150) the results in ascending order, and continues by a construction (9151) of a histogram of the results and a search (9152) of the largest occurrence between the results.
- the microprocessor So out of the hundred scans, the microprocessor will be able to determine, for example, that the number 950 comes up more often than the number 939, 940 or 945.
- the number 950 is then stored, and the processing step (915) of the results is continues with a test (9153) to determine whether the success rate of this number of greatest occurrence is less than a set value. Yes, for example, the value 950 returns more than 7 times on 8 counts, the microprocessor considers that the setpoint has been reached and the step of processing (915) of the results continues with a test step (9154) for determine if there has been good edge detection. Otherwise, the counting according to the invention signals (91530) a bad counting and displays (9159) "no product found".
- This test step (9154) on detection of the edges consists in reading a semaphore which will have been positioned during the steps (91155, figure 12 or 911725, figure 14), indicating that the edges have actually been detected.
- the counting according to the invention signals (91540) poor detection of edges and poster (9159) "no product found”. If so, the processing (915) of the results is continued by a test step (9155) on the detection of the saturation of photosensitive elements of CIS circuits. If so, the counting device according to the invention signals (91550) there is too much light and displays (9159) "no product found”.
- the processing step (915) of the results continues with a step test (9156) to determine if the information read had a good clarity.
- the counting device signals (91560) a contrast defect and displays (9159) "no product found”. In if so, the processing step (915) of the results continues with a test step (9157) on the number of products to determine if this number is greater than zero. If not, the counting device according to the invention indicates (91570) a bad reading and displays (9159) "no product found ". If so, the processing step (915) of the results is ends with a display step (9158) of the number of products and the rate of success.
