Abstract: A CPU 46p arranged in an RF module 46 detects an ID of an other device transmitted by a Bluetooth communication in a state where a main-power-source switch SW48 is turned of and when the detected ID of the other device is already registered in a registering means 50, the main-power-source switch SW48 is turned on. A camera CPU 22 activated thereby detects a file transfer request transmitted by a WiFi communication so as to transfer an image file stored in a recording medium to a request source in response to the detected file transfer request.

Abstract: 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.

Abstract: An edge emphasizing circuit includes a first high-frequency detection circuit and a second high-frequency detection circuit. A spatial frequency of a raw image signal corresponding to a photographed object is detected by the first high-frequency detection circuit or the second high-frequency detection circuit, and a gain corresponding to a detection result is made effective. The gain to be made effective is decreased as the spatial frequency of the raw image signal is low. The gain is applied to an edge emphasizing signal generated by the edge emphasizing circuit, and the raw image signal is added to the edge emphasizing signal to which the gain is applied. Thus, a raw image signal with an emphasized edge is obtained.

Abstract: 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.

Abstract: 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.

On the second bus side, the CPU processes the image data according to a program and records it on a memory card.

Abstract: 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.
