raw image capture using ov528 camera module

[pavan_kumar467]

Hi every one

i need to read an uncompressed data from a ov528 camera module.
For that iam using ucam demo rev2 software.
but unfortunately this software is giving image and ack for only jpeg image.
i think ucam rev4 software can serve my purpose but iam not sure about it.
can anyone help to solve this issue?

i have another problem too...
iam writing a code for my purpose in matlab.
initially i wrote it for jpeg.. i got output image but it contains black spots and some disturbance in the image..
how to solve it?
kindly help

Are you sure your camera is an OV528?

The OV529 is JPEG only, which could explain what you are seeing.

Can you show a sample of your 'black spot' images?

iam sure that my camera module is ov528.
but it is not responding for raw images.
i attached the picture of it.
what might be the reason?

while running matlab the images are as shown in the below attachment..please find it.
please find it and suggest a solution.

Because of the 'symmetry' of the error bars I have the feeling that there may be a bug in your matlab program and the way it is loading the data.

As for the uCam demo snapshot, it is too compressed for me to read and I don't have a CSI class digital enhancement program handy.

sir
thank you for the information.
i will attach the snapshot clearly.

i need one more information.
kindly send the format of the jpeg data.
i mean if i fix packet size as 500...how many bytes will be allotted for header and how many bytes will be the checksum for each frame... Attached files
