Two-dimensional symbol data read apparatus
First Claim
1. A symbol data read apparatus comprising:
- image pick-up means for picking up a bar-code symbol as a two-dimensional image, said bar-code symbol including at least one bar and at least one space;
memory means for storing the two-dimensional image picked up by the image pick-up means as bar-code symbol data;
condition detect means for detecting a bar-code condition of the bar-code symbol from the bar-code symbol data stored in the memory means;
decode means for performing decode-processing to obtain original bar-code symbol data on the basis of bar-code condition data detected by the condition detect means and the bar-code symbol data stored in the memory means; and
output select means for selectively outputting at least bar-code condition data.

Abstract
The symbol data read apparatus comprises a two-dimensional image pick-up device for picking up a bar-code symbol consisting of bars and spaces, as a two-dimensional image. A frame memory stores the two-dimensional image from the two-dimensional image pick-up device, as bar-code symbol data. A condition detect section detects a bar-code condition of the bar-code symbol from the bar-code symbol data stored in the frame memory. A decode section performs decode-processing to obtain original bar-code symbol data on the basis of bar-code condition data from the condition detect section and the bar-code symbol data from the frame memory. An output select section selectively outputs at least data other than the original bar-code symbol data out of the original bar-code symbol data and the other data than the original bar-code symbol data. The other data than the original bar-code symbol data includes inclination data concerning the bar-code symbol and a weighting value for every block.

15. A symbol data apparatus comprising:
-
image pick-up means for picking up a bar-code as a two-dimensional image, said bar-code representing data including at least one bar and at least one space; condition detect means for detecting a pick-up condition of the bar-code, as a numerical value, from the two-dimensional image obtained by the two-dimensional pick-up means, and for comparing the numerical value with a predetermined threshold value, thereby to detect a condition of the bar-code; display means for displaying the condition of the bar-code detected by the condition detect means; and decode means for performing decode-processing to obtain original symbol data on the basis of the two-dimensional image picked up by the two-dimensional image pick-up means. - View Dependent Claims (16, 17)
