Understanding Camera Module Suffixes
Aug 06,2024We have developed a series of camera modules based on OVM6946, OVM6948, OCHTA10, OCFHFA10 and other sensors, some models with P, some models with L, and some with numbers, here below to explain the meaning of these suffixes. T: This is the earliest model, only for muC103. muC103T is based on OVM6946, no LED installed at the tip and the connector is a 1.25mm pitch 6pin holder. P: It is camera only, not come with LED for illumination. It is good for those customers want to use optical fiber as…
Customization of camera module and its back end
Aug 05,2024COMedia has been in the camera module industry for over 30 years. We have developed a range of products to meet various applications. In adition to the standard modules, we provide custom design to meet the special needs of customers. For medical system, we help people in customization of camera module as well as the back end processing board. For Camera Modules Steel sleeve – We can provide either or not the steel sleeve for camera. The steel sleeve can be in different lengths. In order to minimize the OD…
OVM6946 with OV426 image vertical stripe problem analysis and solutions
Aug 05,2024Vertical line in the camera system of OVM6946 is commonly happened in most of the product. We would like to share some experience in resolving this issue. OVM6946 is a 1/18″ color CMOS analog 160 Kpixel (400 x 400 ) camera module with lens. When a long extension cable is used, a vertical noise pattern is often found in the image, as shown in the below figure. The OVM6946 has 4PINs connecting to the OV426 decoder chip, which are AVDD, AGND, XVCLK VOUT. Clock input (4MHz)Cable (50 Ohm impedance)Vout signal…
Understanding OVM6946/OVM6948 vs OCHTA10/OCHFA10
Aug 05,2024OmniVision has quite a few of small footprint camera cube, which is good for medical application. They have aslo changed their model number system for the new parts. Some customers may not familiar with these number. We would like to explain this as below for better understanding. OVM6946 and OVM6948 are the first generation of small camera modules. OCHTA10 and OCHFA10 are the second generation of small camera modules. Camera size OVM6946 1.05 x 1.05 mm OVM6948 0.65 x 0.65 mm OCHTA10 0.65 x 0.65 mm OCHFA10 1.05 x 1.05…
OmniVision Releases OAH0428 Bridge Chip
Dec 25,2022OmniVision recently announced the OCHFA10, OCHTA10 and OAH0428 bridge chips with CameraCubeChip® technology for endoscopes and catheters.Special features of the OAH0428 companion chip include HDR, auto-start, pseudo-global shutter, increased NIR sensitivity and various safety features. This chip is also autoclavable. The OAH0428 has a proprietary 4-pin digital interface for up to 4 meters. Exposure time and gain settings can be sent from an external SPI controller, automatically by the OAH0428’s internal AEC/AGC or manually via the host computer. We do believe this bridge chip has powerful functions but for us,…
