imininingwane yokusebenzisa isithwebuli sekhodi yebha

yini okufanele siyinake lapho sisebenzisa isikena sekhodi yebha?

01 ungaqaxi isithwebuli sekhodi yebha siwuhlobo lwezisetshenziswa ezinhle kakhulu. Idinga idivayisi yangaphakathi yokuguqula ugesi wesithombe ukuze iguqule amasiginali e-analog ibe amasignali edijithali, bese iwathumela kukhompuyutha. Izidingo zokuma zengxenye ngayinye yokubona kulesi silungiselelo sokuguqula ugesi wesithombe ziphezulu kakhulu. Uma siqaqa isithwebuli ngaphandle kokugunyazwa, sizoshintsha ngephutha indawo yalezi zingxenye ze-optical, okuzothinta umsebenzi wokuskena nokuthwebula isithombe sesikena. Ngakho-ke, uma kwenzeka isithwebuli sihluleka, ungaqaqi futhi ulungise ngaphandle kokugunyazwa, futhi uqiniseke ukuthi usithumela kumkhiqizi noma esiteshini esimisiwe sokunakekela; Ukwengeza, lapho uthutha isithwebuli, qiniseka ukuthi ukhiya isikhiya sezokuphepha ngemuva kwesithwebuli ukuze ugweme ukushintsha indawo yezinsiza ezibonayo, futhi uzame ukugwema ukudlidliza noma ukuthambekela kusithwebuli. ngokuthanda

02 vikela izingxenye ze-optical imaging. kwe

isithwebuli sekhodi yebhaIngxenye yokuthwebula ye-optical iyingxenye ebalulekile yesithwebuli sebhakhodi. Kuvamile ukuthi ingxenye ye-optical iwe uthuli ngemva kokusebenza isikhathi eside. Kodwa-ke, uma isithwebuli sisetshenziswa isikhathi eside ngaphandle kokunaka ukugcinwa, uthuli engxenyeni ye-optical luzoqoqana ngokuqhubekayo, okuzonciphisa kakhulu ukusebenza kwesithwebuli, njengamalensi akhanyayo Uthuli olukwi-lens luzokwenza. nciphisa kakhulu ikhwalithi yesithombe, vele amabala noma wenze buthaka umehluko wesithombe. Ngaphezu kwalokho, ohlelweni lokusebenzisa, akunakugwenywa ukuthi isandla sakho sithinte ipuleti lengilazi futhi sishiye izigxivizo zeminwe epuletini. Lezi zigxivizo zeminwe zizophinde zenze buthaka ukukhanya okubonisiwe, ngaleyo ndlela kuthinte ikhwalithi yokuskena yesithombe. Ngakho-ke, kufanele siyihlanze njalo. Lapho uhlanza, sula uthuli lwegobolondo ngendwangu ethambile ethambile, bese uyihlanza ngokucophelela nge-detergent namanzi. Bese sihlanza ipuleti yengilazi. Ngenxa yokuthi ukuhlanzeka kwephaneli kuhlobene ngokuqondile nekhwalithi yokuskena yesithombe, lapho sihlanza iphaneli, siqala ukusula nge-glass cleaner, bese siyisula ngendwangu ethambile eyomile. Ngemva kokusetshenziswa, qiniseka ukuthi umboza isithwebuli sebhakhodi ngesembozo sothuli ukuze uvikele uthuli oluningi ukuthi lungangeni.

03 faka kahle isithwebuli sebhakhodi

Iskena sekhodi yebha akulula ukusifaka njengama-peripherals ekhompuyutha avamile. Indlela yokufaka isithwebuli ihlukile ngokuya nge-interface yaso. Uma isixhumi esibonakalayo seskena kuyi-USB, kufanele uqale uhlole ukuthi idivayisi ye-USB isebenza ngokujwayelekile yini ebhokisini lengxoxo "yezakhiwo zesistimu" lekhompyutha, bese ufaka umshayeli wesithwebuli, qala kabusha ikhompuyutha, xhuma isithwebuli ngoxhumo lwe-USB. , bese ikhompuyutha izothola ngokuzenzakalelayo ihadiwe entsha, Ungabese uqedela yonke eminye imisebenzi ngokuya ngemiyalelo yesikrini. Uma isithwebuli siwuhlobo lwembobo efanayo, kufanele ufake isilungiselelo se-BIOS ngaphambi kokufaka, ushintshe imodi yembobo ehambisanayo ibe yi-EPP kunketho yokumisa idivayisi ye-I / O, bese uxhuma isithwebuli sebhakhodi bese ufaka umshayeli.

04 khipha Umsindo wesithwebuli sekhodi yebha

Ngemva kokusebenza kwesikhathi eside kwesithwebuli sebhakhodi, omunye umsindo ungase ube phakathi nokusebenza. Uma umsindo uphezulu kakhulu, kufanele ususe isembozo somshini, uthole amafutha okuthunga ozowaphonsa ephepheni lasendlini yangasese, usule ukungcola kwamafutha emikhondweni emibili yeqembu lesibuko, bese uphonsa amafutha okuthunga eqenjini legiya lokushayela kanye amabheringi emikhawulweni yomibili yebhande (naka inani elilingene lamafutha), futhi ekugcineni ulungise kahle ukuqina kwebhande.

05 beka kahle into yokuskena yesithwebuli sekhodi yebha

Enqubeni sisebenzisa izithombe, kwesinye isikhathi siyethemba ukuthola izithombe ezitshekile. Abaklami abaningi bavamise ukufaka izithombe kukhompuyutha ngesithwebuli, bese besebenzisa isofthiwe yezithombe ezichwepheshile ukuze bazungezisa izithombe ukuze bathole umphumela wokuzungezisa. Nokho, le nqubo iwukumosha isikhathi. Ngokusho kwe-engeli yokuzungezisa, Ikhwalithi yesithombe izokwehla. Uma sazi ukuthi isithombe sibekwe kanjani ekhasini kusenesikhathi, singasebenzisa i-protractor kanye nonqenqema olungezansi lwesoqobo ukuze sibeke esangempela kurola neplathifomu nge-engeli enembile, futhi sizothola isithombe sekhwalithi ephezulu kakhulu ngaphandle kokuzungezisa. kusofthiwe yokucubungula izithombe.

In the process of actually using images, we sometimes hope to obtain oblique images. Many designers often input the images into the computer through the scanner, and then use professional image software to rotate the images to achieve the rotation effect. However, this process is a waste of time. According to the rotation angle, The quality of the image will decline. If we know how the image is placed on the page in advance, we can use the protractor and the bottom edge of the original to place the original on the roller and platform at an accurate angle, and we will get the highest quality image without rotating in the image processing software.
