  • Patent number: 7834904
    Abstract: A video transmission system typically includes a video server adapted to receive video data from one or more video cameras. In some instance, the video server may be operable to buffer the video data and transmit the video data across a network to various client computing devices. In an improved video transmission system of the present invention, the client computing devices may be further configured to retransmit video data across the network to other client computing devices, thereby reducing the bandwidth and computing load placed on the video server.

  • Patent number: 7834931
    Abstract: When flash photography is performed, an exposure time at a time of a preliminary light emission of a flash is set as short as possible so that the appropriate amount of light required for a main light emission of the flash can be accurately computed. Before the main light emission of the flash, an exposure operation prior to preliminary light emission and an exposure operation at the time of preliminary light emission are performed. After each of these exposures, the pixel signals of individual pixels are intermittently read out at predetermined pixel intervals. The brightness levels of images captured in the exposure operation prior to preliminary light emission and the exposure operation at the time of preliminary light emission are individually detected based on the signals. The amount of light required for the main light emission of the flash is computed based on a difference between the brightness levels.

  • Patent number: 7825966
    Abstract: An image sensor has at least two photodiodes in each unit pixel. A high dynamic range is achieved by selecting different exposure times for the photodiodes. Additionally, blooming is reduced. The readout timing cycle is chosen so that the short exposure time photodiodes act as drains for excess charge overflowing from the long exposure time photodiodes. To improve draining of excess charge, the arrangement of photodiodes may be further selected so that long exposure time photodiodes are neighbored along vertical and horizontal directions by short exposure time photodiodes. A micro-lens array may also be provided in which light is preferentially coupled to the long exposure time photodiodes to improve sensitivity.

  • Patent number: 7821554
    Abstract: An image sensor includes a base an image sensor chip, and a cooling element. The base includes an opening disposed in the base. The image sensor chip is connected electrically to the base and covers the opening. The cooling element is received in the opening and is connected thermally to the image sensor chip. Heat produced by the image sensor chip can be dissipated in time by the cooling elements in the image sensor. The cooling elements maintain the image sensor chip works under a temperature no more than the rated working temperature of the image sensor chip and therefore extend the life of the image sensor, and improve the image quality of the image sensor chip.

  • Patent number: 7821550
    Abstract: A remote image-pickup system includes a camera device including an image-pickup unit for capturing an image of a subject and generating picture signals and a card slot; and a plurality of types of card substrates which are selectively inserted into the card slot and which convert the format of the picture signals so as to output the converted signals to an external device. By inserting different card substrates into the card slot, a plurality of formats of picture signals can be output from the camera device. Accordingly, the format of the picture signals output from the camera device can be flexibly expanded. Further, since many circuits for converting the picture signals need not be incorporated into the camera device, an increase in the size and price of the camera device can be prevented.

  • Patent number: 7812870
    Abstract: Systems and related methods have been achieved to convert in an analog domain the output of color image sensors into another color space. A chosen implementation converts the output of red, green, blue and white image sensors to the YcrCb color space, wherein the white image sensors are either extended dynamic range (XDR) image sensors or are of the same type as the other image sensors but have a larger size. The output of the white pixels can be used without conversion directly for the luminance Y value, thus achieving a very simple method for a conversion to YCbCr color space. Analog amplifiers, assigned to each of the red, green, and blue image sensors, have a gain according to the matrix describing the conversion from RGB to CbCr. Analog adders, assigned to Cb and Cr are adding the coefficients required for the computation of Cb and Cr. Finally the values of Y, Cb and Cr are converted to digital values. White pixels are advantageous but not required using the present invention.

  • Patent number: 7808539
    Abstract: Pixel signals are sequentially output from an image sensor in a reverse order to an order in which light sensing cells are arranged with respect to one of a horizontal direction and a vertical direction. In an image processor, first, a data reading part transfers the pixel signals in the same order as corresponding light sensing cells are arranged with respect to both of a horizontal direction and a vertical direction, and a signal sequence of the pixel signals is changed. Then, the pixel signals which are output group by group are sequentially selected by a selector in accordance with a sequence of groups. As a result, the pixel signals can be supplied from the selector in an order conforming a two-dimensional array of the light sensing cells, to thereby facilitate color interpolation which is to be later performed by a color interpolator.

  • Patent number: 7804527
    Abstract: In case there is no image file with an event name in a memory card when a digital camera is turned on the first time on the day, an asking sentence asks whether to create a new event name or not. When “Yes” is selected, event tag data showing “Event 1” is applied to an image file. When “No” is selected, event tag data showing “No event” is applied to an image file. In case there is an image file of “Event n” in the memory card, a selection screen is displayed to select one of options, which are to apply a new event name “Event n+1”, to apply the existing event name “Event n” and to apply no event name. In the second or later turn on of the digital camera, the event name selected in the first turn on is automatically applied to the event tag data.
