摘要： An image processing apparatus capable of performing a correction process by filtering speedily and easily. A digital signal processor captures image data including effective area data from within a preset range of an image pickup device and ineffective area data from outside the preset range of the image pickup device. The digital signal processor superimposes a defective pixel detection signal and an ineffective image data detection signal to thereby generate a defective pixel determination signal. When a target pixel in the image data is determined based on the defective pixel determination signal as a determined-as-defective pixel, the digital signal processor corrects the value of the target pixel using values of the image data associated with ones, which are not determined, based on the defective pixel determination signal, as the determined-as-defective pixel, of pixels around the target pixel.

摘要： An electronic apparatus includes a memory, first and second bus masters, a counting unit and a control unit. The first and second bus masters are capable of accessing the memory. The counting unit counts an amount of addresses reserved by the second bus master for accessing the memory. The control unit controls to avoid permitting a request made by the second bus master if a value counted by the counting unit becomes larger than a first threshold value, until the value counted by the counting unit becomes smaller than a second threshold value. The request made by the second bus master is used to reserve addresses of the memory, and the second threshold value is smaller than the first threshold value.

摘要： An image capturing apparatus 100 first executes JPEG encoding on RAW data. On the basis of the compression ratio of JPEG image data obtained, the image capturing apparatus 100 selects a Huffman table to encode the RAW data. With the higher compression ratio of the JPEG data obtained, the image capturing apparatus 100 assumes that the RAW data is image data with a larger number of low frequency components. The image capturing apparatus 100 thus selects a Huffman table that assigns a particularly short code to a predictive differential value with a smaller absolute value. In contrast, with the lower compression ratio of the JPEG image data obtained, the image capturing apparatus 100 selects a Huffman table that assigns a code of a relatively equal length to the predictive differential value regardless of its absolute value.
