Aptina 4K Video Sensor Lands in Ikegami Camera

Ikegami announced that its new GFCAM HD camcorder for HD cinema production is equipped with a 4/3-inch optical format Aptina 4K (4096×2160) CMOS sensor. The camera uses both horizontal and vertical oversampling to improve MTF and and provides 24p/25p/30p native recording.

Update: The original Ikegami PR has been modified and references to Aptina sensor and Four-Thirds GFCAM have been removed. Still, the original text is temporarily kept in Google search and some other sites, like Consumer Electronics Net:

"Ikegami also addresses HD cinema production with the introduction of the new Four-Thirds GFCAM. Based on the workflow-efficient tapeless GFCAM HD Flash camcorder, the new camera is equipped with a 4/3-inch optical format Aptina 4K CMOS sensor for high resolution digital filmmaking. Providing excellent MTF both horizontally and vertically with over-sampling and 24p/25p/30p native recording, the camera uses lower-cost 64/128 GB Flash media that employs MLC (Multi Level Cell) technology with 10,000 times rewrite capacity. The new Four-Thirds GFCAM is designed to accept large format PL-Mount lenses for film-style high-aperture, shallow depth-of-focus cinematography."

  1. It seems like GFCAM series use to work with 3x2/3 CCD chips.. I dont see anywhere indication that they have moved to 4/3 Bayer Chip in this camera

  2. Please someone explain that 4000Hx2000V=4k

  3. In cinema, the 2k and 4k formats are referring to the number of pixels in a single line of the sensor.

    they are not concerned with the height of the sensor (number of lines) because depending on the format chosen, the vertical size changes.

    16:9 would have more lines in the image than a 2.1:1 widescreen.

    Hence the 4K refers to sensors that are 4096 pixels wide.

  5. @ "Can you post have a link to the 4K 4/3 Ikegami Camera ?"

    The original version of Ikegami PR, used to be at the link in the post, had this reference. Now it seems they have deleted it - very interesting! The original wording is still seen at Google, not sure for how long till Google updates its cache:

    Also, some other sites quote the original PR in full:

    Weird story, indeed.

  6. I just bought a HDTV. And now I understand why I can see FPN on the image sometimes. Should be CMOS sensor in the camera ...
