Reading a JPEG file with jl
I downloaded a JPEG file on my VC Smart Camera and then tried to load in into DRAM with the command "jl", but I got an error message./Displaying a JPEG image on the Smart Camera video output.
VC cameras are not able to read all JPEG pictures yet (the header changes from one program to another), but we are working to solve this issue once for all.
In the meantime, you can use the attached program (please log in to download), which converts a BMP image into a readable JPEG image. Of course, if you already have a JPEG image, you'll have to convert it to BMP with any software, and then use bmpjpg2.exe.
Use the following settings with this software tool (image height and width must be multiples of 8):
- Quality: 80
- Performance: Best Quality
- Scale: 1:1
- Format: 8 bit
- Compression/Decompression: "Gray Scale"
Ensure that the file extension in flash memory is *.003 (rename the file during FTP upload if neccessary).
"SampleImages.zip" contains the a bitmap image (1.bmp), a screenshot of the conversion settings (CreateJPG.gif"), the produced Jpg (1080.jpg") and a screenshot of the camera video output ("bild.jpg") after using "jl 1080").
Please also see the attached application example for display of color JPEGs in the overlay. (Log in first to be able to display downloads, thank you.)
