The high definition FCB-EV7500, part of Sony’s ‘enhanced visibility’ series of camera modules, is now available from Stemmer Imaging. Operation at full HD of 1080p/60 and 1080p/50 is supported. A visibility enhancer, wide dynamic range and adaptive 2D/3D noise reduction combine to give outstanding image quality even in challenging conditions. The Sony Exmor CMOS sensor gives significantly higher sensitivity than previous Sony HD models.
The new sensor and a newly developed image signal processor give improved image quality in terms of picture sharpness and colour optimisation. The ‘visibility enhancer’ is a key new feature which allows for adaptive contrast display in the captured image. Various contrast settings can be applied to different areas of the image to give the best overall picture. This facility is ideal for use in mist or smoke as well as in scenes with a general wide dynamic range.
In addition there is a wide dynamic range function which allows 2 frames to be captured at varying exposures at full resolution in order to combine high and low contrast areas. This is extended to four frames when operating at 720p resolution. This new wide dynamic range feature is then combined with the visibility enhancer to give great results in all lighting conditions.
In addition, the high frame rate at full 1080p resolution (previous HD modules only supported 30 fps) means that fast moving images are seen in a more natural smooth motion. 30x optical zoom is provided. Adaptive 2D and 3D noise reduction further enhances image quality whilst minimising motion blur. The new camera will automatically adapt the level of 2D/3D noise reduction in different areas of the picture depending on whether the area is static or moving. 3D noise reduction is applied to static areas by comparing multiple frames to reduce noise most effectively. 2D noise reduction is applied to areas of movement to reduce noise without trailing effects.
