24、e. The codes for this byte as well as the maximum size of the recorded image are defined in tables 5 and 6 as explained in the note below. Codes 0-10 from table 5 shoul d be used for single fingers. Code s 13 and 14 from table 5 are u sed for the images containing four fingers from the right hand an
25、d left hand respectively. Code 15 from table 5 is the code for accommodating the simultaneous capture of the two thumbs. Additional Codes to accommodate the simultaneous capture of common 2-finger and 3-finger combinations from standalone or mobile identification devices are defined in Table 5a. Thi
26、s table also defines the minimum areas and dimensions for each combination. Codes for palm mages are f ound in table 6. For full palms the cap tured area should extend from the “wrist bracelet“ through the second joint of the fingers. Similarly, the captured area of the upper palm should extend from
27、 the interdigital area through the second joint of the fingers. The lower palm will cover the area from the “wrist bracelet“ through the interdigital area. All dimensions and areas listed in these tables are maximums. 7. Between Tables 5 and 6 insert the following table: Table 5a Multiple Finger Pos
