Semakin tinggi resolusinya, semakin banyak detail yang dapat dilihat saat foto diperbesar. 03:00<\/p>\n
Struktur sensor:<\/p>\n
lensa\/filter warna\/area peka cahaya, lensa mengumpulkan warna cahaya tertentu, filter warna menyaring warna cahaya lain, dan memproyeksikan satu warna cahaya ke area peka cahaya. 04:07<\/p>\n
Mode koneksi Sensor dan substrat:<\/p>\n
COB: modul mendapatkan sensor die dan menghubungkan sensor ke substrat melalui kabel emas.<\/p>\n
CSP\/TSF: Sensor telah dihubungkan ke substrat dan dikemas saat dikirim. 06:00<\/p>\n
Catatan: Tata letak MIPI:<\/p>\n
Garis sinyal Mipi memiliki panjang yang sama dan simetris<\/p>\n
Posisi lubang simetris<\/p>\n
Perkiraan Tempat Transisi Tata Letak 06:31<\/p>\n
Proses pembuatan sensor<\/p>\n
Ada BSI dan FSI, BSI lebih baik. Relatif dapat mendukung komponen yang lebih tipis, aperture besar, kecerahan lebih tinggi. 10:00<\/p>\n
<\/p>\n
Responsivitas Sensor mengacu pada efisiensi konversi fotolistrik, dalam V\/Lux-sec. (Tegangan keluaran per unit pencahayaan) 10:45<\/p>\n
Potongan IR dan Kaca Biru:<\/p>\n
Fungsi pemotongan IR adalah untuk menyaring (memantulkan kembali) frekuensi cahaya yang tidak dapat dilihat oleh mata manusia, dan mata manusia dapat melihat 400~700nm.<\/p>\n
Kaca biru menyerap sinar inframerah dan tidak mudah melakukan refleksi sekunder di dalamnya. 22:50<\/p>\n
Lingkaran gambar Lensa perlu menutupi area sensitif sensor. 25:00<\/p>\n
Bayangan lensa:<\/p>\n
Ini mengacu pada distribusi cahaya yang tidak merata, seperti pencahayaan di bagian tengah dan meluas ke luar hingga redup. Hal ini terutama karena sebagian besar cahaya terkonsentrasi di bagian tengah, dan karena lokasi pencitraan dari panjang gelombang yang berbeda berbeda. 27:00<\/p>\n
FNO. Perhitungan:<\/p>\n
Fno.= f\/A f adalah panjang fokus dan A adalah ukuran bukaan. 29:00<\/p>\n
TTL:<\/p>\n
Jarak dari permukaan lensa ke permukaan sensor. Definisi ini memudahkan perhitungan tinggi modul.<\/p>\n
Tinggi modul = TTL + ketebalan sensor + tinggi substrat<\/p>\n
Sudut Pandang:<\/p>\n
Sudut pandang modul harus konsisten dengan Sudut lensa, jika tidak, apabila Sudut lensa relatif besar, mungkin akan terjadi Sudut gelap.<\/p>\n
CRA:<\/p>\n
Sudut dari pusat cermin ke area peka cahaya.<\/p>\n
Jika CRA tidak cocok, hal itu menyebabkan fenomena bayangan warna.<\/p>\n
Saran CRA: CRA Lensa < CRA Sensor; jika tidak, cahaya mudah terpantul. Selain itu, CRA harus sesuai,<\/p>\n
Perbedaan antara Lensa dan Sensor adalah dalam 2\u00b0. 36:00<\/p>\n
Setelah keputusan Sensor, tentukan lensa.40:51 sesuai dengan lingkaran gambar dan CRA<\/p>\n
CRA dapat merujuk ke http:\/\/www.opticsky.cn\/simple\/t11533.html<\/p>\n
VCM<\/p>\n
Ada dua yaitu open loop dan closed loop, closed loop ada close loop dan OIS ada dua. 48:00<\/p>\n
Loop tertutup memiliki akurasi yang relatif lebih tinggi dan kecepatan pemfokusan yang lebih cepat, serta konsumsi daya yang rendah, dan efek pencitraan lebih menonjol dalam kondisi cahaya rendah. Kerugiannya adalah kompatibilitas perangkat lunaknya buruk dan perlu dikembangkan ulang dan di-debug.<\/p>\n
OIS > tutup loop > buka loop<\/p>\n

The higher the resolution, the more detail can be seen when the photo is enlarged. 03:00 Sensor structure: lens \/color filter\/ photosensitive area, lens collects a specific color of light, color filter filters other colors of light, and projects one color of light to the photosensitive area. 04:07 Connection mode of Sensor and substrate: COB: module gets the sensor die and connects the sensor to the substrate through the gold wire. CSP\/TSF: The sensor has been connected to the substrate and packaged when shipped. 06:00 Note: MIPI layout: Mipi signal line is equal length and symmetrical The hole position is symmetrical Estimate of Layout transition place 06:31 Sensor manufacturing process There are BSI and FSI, BSI is better. Relatively can support thinner components, large aperture, higher brightness. 10:00 Sensor's Responsiveness refers to the photoelectric conversion efficiency, in V\/Lux-sec. (Output voltage per unit of illumination) 10:45 IR cut and Blue Galss: The function of IR cut is to filter out (reflect back) the light frequency that the human eye can not see, and the human eye can see 400~700nm. Blue glass absorbs infrared rays and is not easy to do secondary reflection inside. 22:50 The image circle of the Lens needs to cover the sensitive area of the sensor. 25:00 Lens shading: It refers to the uneven distribution of light, such as lighting in the center and extending outward to dim. This is mainly because most of the light is concentrated in the middle, and because the imaging locations of different wavelengths are different. 27:00 FNO. Calculation: Fno.= f\/A f is the focal length and A is the aperture size. 29:00 TTL: The distance from the lens surface to the sensor surface. This definition facilitates calculation of module height. module height = TTL + sensor thickness + substrate height FOV: The viewing Angle of the module must be consistent with the Angle of the lens, otherwise when the Angle of the lens is relatively large, there may be a dark Angle. CRA: Angle from mirror center to photosensitive area. When CRA does not match, it causes color shading phenomenon. CRA suggestion: Lens CRA < Sensor CRA; otherwise, light is easily reflected. In addition, the CRA should match, The difference between a Lens and a Sensor is within 2\u00b0. 36:00 After Sensor's decision, determine lens.40:51 according to image circle and CRA CRA may refer to http:\/\/www.opticsky.cn\/simple\/t11533.html VCM There are open loop and closed loop two, closed loop has close loop and OIS two. 48:00 The closed loop has relatively higher accuracy and faster focusing speed, and the power consumption is also low, and the imaging effect is more prominent in low light conditions. The disadvantage is that the software compatibility is poor and needs to be redeveloped and debugged.
