  • Publication number: 20100309360
    Abstract: An electronic camera according to the present invention includes: an image pickup part for picking up a subject image to produce image data; a processing part for processing the image data outputted from the image pickup part to produce a quickview image for monitor display and also produce image data for record on a recording medium; and a monitor part for displaying the quickview image. The processing part commences displaying the quickview image on the monitor part prior to the production of the image data for record. This processing allows the display of the quickview image to be commenced without waiting for completion of the production of the image data for record. Therefore, it is possible to shorten the time lag occurring at displaying the quickview image, thereby improving the convenience of the electronic camera.

  • Publication number: 20090160969
    Abstract: An image capturing apparatus can use a reading time from an image sensor efficiently. To achieve the object, the image capturing apparatus includes an image capturing unit which separates a color image of a subject being captured by an image sensor having pixels of colors into three or more fields and outputs said three or more fields successively, and an image processing unit which generates a low-resolution image which is lower in resolution than the color image obtained by the image capturing unit, based on output of one or more fields among said three or more fields, said one or more fields being able to extract color information of all the colors, wherein the image processing unit starts generation of the low-resolution image in a period in which fields other than said one or more fields for generating the low-resolution image are read.

  • Publication number: 20090009629
    Abstract: An electronic camera of the present invention includes: an imaging unit capturing a subject to generate an original image; a derivative image generating unit reducing resolution or color of the original image to generate a derivative image for transfer; a recording unit recording the original image and the derivative image thereon such that the original image and the derivative image get associated with each other; and a transfer unit transferring the derivative image recorded on the recording unit to an external transfer destination. In this configuration, the recording unit finds the derivative image (original image) by referring to the association with the original image (or derivative image), thereby collectively managing the original image and the derivative image. This makes it possible to prevent a user from being confused at image management due to the original image and the derivative image being the same image.

  • Patent number: 7336302
    Abstract: A frame memory device is employed in a digital camera, for example, to output raster-scanned digital color image signals at lower resolution than that of original image signals. The order of sequentially received original raster-scanned digital color image signals is rearranged, and the rearranged signals are sequentially stored in a memory having a two-dimensional address structure such that vertical addresses represent the order of entry of respective scan lines that constitute the image signals and horizontal addresses represent the order of entry of respective signals that belong to each of the scan lines. The stored rearranged signals are subsampled and read out while skipping horizontal and vertical addresses of the memory at regular intervals. The image signals may comprise YCBCR color signals having a sampling ratio of 4:2:2. Sequentially received C signals in the order of CB?CR?CB?CR, for example, are rearranged in the order of CB?CB?CR?CR.

  • Patent number: 7280136
    Abstract: An electronic camera of the present invention comprises an image pickup part, a microprocessor, and a multi-port memory that has a first port and a second port through which data can be independently accessed. The microprocessor writes the image data to the multi-port memory through the first port. The digital signal processor reads the image data from the multi-port memory through the second port, performs the software signal processing on the image data, and writes the processed data to the multi-port memory through the second port. The microprocessor reads the image data on which the software signal processing has been performed from the multi-port memory through the first port and records the read image data from the multi-port memory on a recording medium that stores data.
