JAI has released two new members of the C3 Basic series of cameras. These 1.4 Megapixel cameras with GigE Vision interface – the BM-141GE (monochrome) and the BB-141GE (Bayer colour) - can be used for a variety of machine vision applications, but are particularly well-suited to outdoor applications characterised by wide ranging and continuously changing lighting conditions.
The BM-141GE and BB-141GE are designed around Sony's ICX-285 2/3-inch progressive scan CCD (1392 x 1040 pixels) providing excellent sensitivity and spectral response.
The cameras deliver a signal-to-noise ratio of greater than 58dB, producing high quality images even in night time illuminated situations. Both cameras feature an advanced automatic exposure function that can simultaneously control gain, shutter, and lens iris to maintain optimum exposure levels across a wide range of changing lighting conditions.
The BM/BB-141GE cameras offer pre-set shutter speeds up to 1/10,000 second and programmable exposures as short as 63µs for capturing fast moving objects. A variety of trigger modes are provided including reset continuous triggering (RCT), which enables the camera to operate in continuous mode while awaiting a trigger signal. This allows triggering to be used without sacrificing the camera's auto exposure capabilities.
With the decimation readout feature, it is possible to thin out the number of lines read out from the CCD chip to obtain a draft mode image. This draft mode is particularly useful in traffic and security applications characterised by idle time between events. During the idle time the camera runs in draft mode (with reduced image size) freeing up data transmission bandwidth and saving computing power.
Other features such as sequence trigger mode, fixed/variable partial scanning, pre-processing together with a fast pixel clock frequency (58MHz), 30fps and NIR-capabilities, also position these cameras as particularly useful for demanding machine vision applications as well as food sorting and medical applications.
The JAI GigE Vision Camera Software package contains all SDK components required for easily integrating the cameras into vision applications. The SDK also contains JAI control tool and a highly efficient filter driver.
