    摘要: A digital camera includes a mode set switch. If a camera mode is set by mode set switch, the image data corresponding to a subject image taken by a CCD imager is processed by DMA, and outputted through a first bus onto a monitor. If a shutter button is operated, the first bus is connected to a second bus by a bus bridge and the image data is transferred from a first bus side to a second bus side. On the second bus side, the CPU processes the image data according to a program and records it on a memory card.

    摘要: An image processing apparatus (10) includes a bus (B1) and a bus (B2). A series of processes for creating YUV image data for HDTV is executed by means of a bus (B1) and an SDRAM (32). Furthermore, a series of processes for creating YUV image data for LCD monitor (66) is executed by means of a bus (B3) and an SDRAM (54). Here, the resolution of the YUV image data for HDTV is higher than that of the YUV image data for LCD monitor. That is, the bus (B1) and the SDRAM (32) are utilized for high-resolution moving image data processing, and the bus (B3) and the SDRAM 54 are utilized for low-resolution moving image data processing.

    摘要: Digital camera includes a CCD imager having VGA resolution. The camera signal of subject image taken by the CCD imager is subjected to a predetermined process by a signal processing circuit, whereby image data is created having 640 pixel×980 lines. Meanwhile, a CPU enables cut-out circuit when a 1-tims mode is set by a zoom button, and a cut-out circuit when a 2-times mode is set by the zoom button. The thin-out circuit performs thinning out pixel data, every other pixels and lines, on the image data having 640 pixels×480 lines, outputting image data having 320 pixels×240 lines. The cut-out circuit cuts 320 pixels×240 lines of image data from a center of the image data of 640 pixels×480 lines.

    摘要: A digital camera includes a CCD imager having an interline transfer scheme. A first charge produced due to first exposure is read from light receiving elements positioned vertically intermittently. A second charge produced due to second exposure is also read from the same light receiving elements to vertical transfer regions. Here, the first charge is vertically moved simultaneously with or prior to reading out the second charge. The moving distance, at this time, is equal to or greater than a distance that the light receiving elements continue in the vertical direction. As a result of this, the second charge will not be mixed with the first charge. The first and second charges are subjected to a compositing process to display a composite image on an LCD.

    摘要: A digital camera includes a CCD imager mounted at a front with a primary color filter. An optimal shutter speed is calculated based on a camera signal outputted from the CCD imager upon a pre-exposure. Where a calculated optimal shutter speed is low, a timing generator drives the CCD imager by a pixel-mixing scheme. Charges are first read out of part of the light receiving elements and transferred in a vertical direction. When the charges are transferred by a predetermined distance, the remaining part of the light receiving elements are read out. As a result of this, the charges of a same color of color components are mixed together. That is, a filtering process is effected within the CCD imager to remove aliasing components.

    摘要: A digital video camera includes an addition circuit in which an offset set by a CPU is added to an output from an A/D converter. A clamp level calculation circuit calculates a clamp level on the basis of an average level of eight pixels included in each line within a back end OB (optical black) level detection area in a normal mode, or calculates a clamp level on the basis of an average level of two pixels included in each line within a front end OB level detection area in a quadruplication mode. A first subtraction circuit subtracts the clamp level from an output of the addition circuit so as to clamp the output of the addition circuit. An output of the first subtraction circuit is clipped at a zero-level by a zero-clipping circuit, and an output of the zero-clipping circuit is applied to a second subtraction circuit through a low-pass filter, whereby the same offset can be subtracted from the output of the zero-clipping circuit.

    摘要: A digital camera includes a CCD imager which outputs 640 pixels×480 lines of camera signal in a raster scan scheme. The camera signal outputted from the CCD imager is subjected to a predetermined signal processing whereby created are 640 pixels×480 lines of original image data and 80 pixels×60 lines of thumbnail image data. Both the created original image data and thumbnail image data are written to a SDRAM. The writing of the thumbnail image data is performed during a horizontal blanking period of the original image data. As a result, image data writing operation completes within a 1-frame period of time.
