Example) Dump of top 112 bytes of FRM form data in RAW-10bit
The image data made by SVI system has a DAT form or an FRM form.
The DAT form records an image by a pixel clock unit. The DAT form is comprised
of synchronization signal information 1 byte, a 2 bytes unit of image data
1 byte by a clock unit. For the record of the pixel clock unit, it can record
it during the blanking period.
As for the FRM form, a header of 40 bytes was added to data output by image
sensor every frame. The FRM form records the output data from a camera.
Padding data is added to the number of bytes of the frame area of the FRM
form to be divisible with 64. We recommend an FRM form to let you recode
it by the SVI system in SVIview or SVOgenerator when I convert it into SVI
format.
We show to the top details of the SVI picture file format of the FRM form.
