A good user manual
The rules should oblige the seller to give the purchaser an operating instrucion of JAI AD-081, along with an item. The lack of an instruction or false information given to customer shall constitute grounds to apply for a complaint because of nonconformity of goods with the contract. In accordance with the law, a customer can receive an instruction in non-paper form; lately graphic and electronic forms of the manuals, as well as instructional videos have been majorly used. A necessary precondition for this is the unmistakable, legible character of an instruction.
What is an instruction?
The term originates from the Latin word „instructio”, which means organizing. Therefore, in an instruction of JAI AD-081 one could find a process description. An instruction's purpose is to teach, to ease the start-up and an item's use or performance of certain activities. An instruction is a compilation of information about an item/a service, it is a clue.
Unfortunately, only a few customers devote their time to read an instruction of JAI AD-081. A good user manual introduces us to a number of additional functionalities of the purchased item, and also helps us to avoid the formation of most of the defects.
What should a perfect user manual contain?
First and foremost, an user manual of JAI AD-081 should contain:
- informations concerning technical data of JAI AD-081
- name of the manufacturer and a year of construction of the JAI AD-081 item
- rules of operation, control and maintenance of the JAI AD-081 item
- safety signs and mark certificates which confirm compatibility with appropriate standards
Why don't we read the manuals?
Usually it results from the lack of time and certainty about functionalities of purchased items. Unfortunately, networking and start-up of JAI AD-081 alone are not enough. An instruction contains a number of clues concerning respective functionalities, safety rules, maintenance methods (what means should be used), eventual defects of JAI AD-081, and methods of problem resolution. Eventually, when one still can't find the answer to his problems, he will be directed to the JAI service. Lately animated manuals and instructional videos are quite popular among customers. These kinds of user manuals are effective; they assure that a customer will familiarize himself with the whole material, and won't skip complicated, technical information of JAI AD-081.
Why one should read the manuals?
It is mostly in the manuals where we will find the details concerning construction and possibility of the JAI AD-081 item, and its use of respective accessory, as well as information concerning all the functions and facilities.
After a successful purchase of an item one should find a moment and get to know with every part of an instruction. Currently the manuals are carefully prearranged and translated, so they could be fully understood by its users. The manuals will serve as an informational aid.

T ech Note TN-0902 Date: 02/06/09 USING A 2CCD CAMERA T O CREA TE HIGH-DYNAMIC RANGE IMAGES Some imaging scenarios push dynamic range beyond the capabilities of the typical sensor . This is especially true where incident light is present (e.g., imaging a light source and the surrounding area). This can also occur in situations with bright reecti[...]

T ech Note 2 NO. TN-0902 pg 2 Example 1 - Maximum Dynamic Range (no overlap) T o create an image that spans the maximum range of light intensities, use shutter settings to calibrate the 2 sensors so that Sensor B = Sensor A * 1024. In other words, the light needed to generate 100 counts from Sen - sor B is 1024 times the light needed to create 100 [...]

T ech Note 2 Displaying a high dynamic range image on a standard monitor will require mapping the output to t the monitor’ s dynamic range capability . For the image described above, start by creating a 20-bit image map using the raw pixel data. Then create a 10-bit image map to display on the monitor by dividing the 20-bit im- age map by 1024[...]

T ech Note 2 Now , our post processing routine could be handled as follows: if (pixel B < 16){ pixel_out = pixel A }else{ pixel_out = pixel B * 64 } By overlapping the two sensor responses, this approach utilizes the full precision of the lower 10-bits while reducing the effect of noise at the transition point and greatly increasing the precisio[...]

T ech Note 2 Now as Sensor A approaches its saturation point (512 – 1023 counts) the output uses the average of both sen - sors’ data to “smooth” the transition between the two sensor response graphs (see Figure 6). It still limits the use of the lowest bits on Sensor B (those that are most susceptible to noise) and keeps the calibration fa[...]

T ech Note 2 For example, in a 4-bit overlap scenario, we still set the shutter for Sensor B to be roughly 64 times faster than Sensor A (i.e., a pixel on Sensor A with a value of 256 would have a value of 4 on Sensor B). But, de - pending on our objective, we apply a post processing factor of less than 64 and add an offset value to get the two out[...]
