Abstract: Processing raw image data in a camera includes computing a luminance image from the raw image data, and computing a chrominance image corresponding to at least one of the sensor's image colors from the raw image data. The luminance image and chrominance image(s) can represent the same range of colors able to be represented in the raw image data. The chrominance image can have a lower resolution than that of the luminance image. A camera for performing the method is also disclosed.

Abstract: A method of processing image data that is represented in a frequency domain includes the step of applying a noise signal to the image data to yield noise-applied image data. In at least one embodiment, the image data includes one or more sets of coefficients arising from application of a discrete cosine transform, each set of coefficients comprising a DC coefficient and one or more AC coefficients. The noise signal is applied to the image data by modifying one or more of the coefficients in one or more of the sets. The modifying includes replacing one or more of the AC coefficients with random or pseudo random numbers having a distribution. Noise present in the image data may be equalized, prior to the step of applying the noise signal.

Abstract: A digital video camera, including a heat management system, which includes at least one inlet and at least one outlet in the housing to enable air to flow through the housing. The heat management system also includes a first heat sink thermally connected to an image sensor(s), and a second heat sink thermally connected to a data processing unit(s), and a centrifugal fan. The centrifugal fan is configured to draw air into the front of the fan in an axial direction and push air radially out in a sideways direction, whereby air travels through the inlet(s) over the first heat sink and then over the second heat sink to the outlet(s).
