摘要： A photographing device may reduce additional consumption of memory capacity and power and capture high resolution images. A method of controlling the photographing device includes storing first resolution input images acquired from live view images in a buffer; storing, according to an input of a time point, a second resolution input image acquired at the time point from the live view images in the buffer; and generating a result image based on the second resolution input image when the second resolution input image, which is stored within a threshold time from a photography command reception time point, is found in the buffer, and generating at least one of the stored first resolution image images as the result image when the second resolution input image, which is stored within the threshold time from the photography command reception time point, is not found in the buffer.

摘要： An imaging system may output embedded data in an output frame. Selected bits of pixel data words, corresponding to data read out from imaging pixels and non-imaging pixels, may be modified to correspond to bits of embedded data. Modifying pixel data words may include receiving a pixel data word and decatenating the pixel data words into fragments of the data word. A first fragment may correspond to bits of the data word that are replaced by embedded data bits output from an embedded data engine. A second fragment may be modified using arithmetic circuitry based on whether the embedded data bits that replace the first fragment are the same as bits of the first fragment. An output data word may be produced that includes embedded data bits at its least significant bits, most significant bits, or intermediate bits.

摘要： An imaging apparatus for performing efficient signal processing depending on the operational mode. In the finder mode, a CCD interface 21a decimates horizontal components of image data supplied from an image generating unit 10 to one-third and moreover processes the decimated image data with data conversion and resolution conversion to produce Y, Cb and Cr image data which are routed to and written in an image memory 32 over a memory controller 22. In the recording mode, the CCD interface 21a causes the image data from the image generating unit 10 to be written in the image memory 32 via memory controller 22 after decimation and gamma correction etc. The camera DSP 21c reads out the image data via memory controller 22 from the image memory 32 to effect data conversion for writing the resulting data via memory controller 22 in the image memory 32.

摘要： Two local buffers are provided between an image processing unit and an image compression and expansion unit for compression into a predetermined format. Write and read control units serve to alternately use the two local buffers. As a result, process flow starting from the image processing unit to generate compressed image data by the image compression and expansion unit requires no main memory, whereby high-speed image processing is allowed with low power consumption.

摘要： An image sensor of a camera system captures an image over an image capture interval of time, and waits a blanking interval of time before capturing an additional image. The captured image is provided to a frame controller, and is buffered until an image signal processor accesses the captured image. The image signal processor processes the accessed image over an image processing interval of time, producing a processed image. The image processing interval of time is selected to be greater than the image capture interval of time, but less than the sum of the image capture interval of time and the blanking interval of time. By reducing the image capture interval of time but maintaining an image processing interval of time, rolling shutter artifacts are beneficially reduced without increasing the processing resources or power required by the image signal processor to process the image.

摘要： An image sensor compresses image data prior to transmitting the image data to a DSP. The image sensor captures light representing an image, for instance via a camera's aperture. A focal plane array converts the captured light into pixel data. The pixel data is sorted into categories, and is compressed in parallel by a compression engine. The compressed pixel data is then sent to a DSP, which may be located off-chip. The DSP then decompresses the compressed pixel data, performs image signal processing operations on the compressed pixel data, and then compresses the processed pixel data into a digital image format. The image sensor may buffer the pixel data for one or more images to accommodate for slowdown by the compression engine. The pixel data may be sorted by row and column of a pixel array. Alternatively, the pixel data may be sorted by color from a Bayer color filter.
