    • PROBLEM TO BE SOLVED: To read and write data to and from pixels of an active matrix display device. SOLUTION: A pixel includes: a transistor 5 which is turned on and off with a selection signal of a selection line; a static memory (including two driving transistors 2 and 4) connected to a data line 9 through the transistor 5; and light emitting elements 1 and 3 whose light emission is controlled according to the storage state of the static memory. In a write mode, the selection transistor 5 is turned on and set data is set for the data line 9 to write the set data to the static memory. In a read mode, the selection transistor 5 is turned on and the data line 9 is placed in a floating state to read the storage contents of the static memory out to the data line.

    • PROBLEM TO BE SOLVED: To identify a flash light exposure area and a non flash light exposure area at the time of flash (or strobe) photographing. SOLUTION: An area judgement section 38 of a digital camera acquires a preview image and a preview image during pre-flash, and judges an area where difference between both images exceeds a threshold as an area irradiated by flash light. In addition, the area judgement section 38 acquires the preview image and a captured image during flash, and judges an area where difference between both images exceeds a threshold as an area irradiated by flash light, after resizing the preview image and comparing with the captured image.

    • PROBLEM TO BE SOLVED: To provide a technique for suppressing deviation in white balance even for an image such that the rate of a dark area is larger than the rate of a light area like a night scene image.
      SOLUTION: A white balance gain calculating unit 46 calculates a white balance gain for an image based upon color differences of pixel areas whose at least luminance level is equal to or larger than a reference luminance level among all pixel areas of the image. A correction coefficient calculating unit 50 finds a correction coefficient based upon at least one of imaging sensitivity corresponding to the image, the rate of the dark part area, and whether flash light is emitted when the ratio of the dark part pixel areas whose luminance and color difference meet predetermined conditions to all the pixel areas of the image is equal to or larger than a reference ratio, and instructs the white balance gain calculating unit 46 to correct the white balance gain based upon the correction coefficient.

    • 要解决的问题:提供一种即使对于图像来抑制白平衡偏差的技术,使得暗区域的速率比夜景图像的亮区域的速率大。 解决方案:白平衡增益计算单元46基于图像的所有像素区域中的至少亮度等于或大于参考亮度水平的像素区域的颜色差来计算图像的白平衡增益。 校正系数计算单元50基于与图像相关的成像灵敏度,暗部分区域的速率以及当亮度和颜色的暗部像素区域的比率是否发射闪光时,发现校正系数 符合图像的所有像素区域的预定条件的差异等于或大于参考比,并且指示白平衡增益计算单元46基于校正系数校正白平衡增益。 版权所有(C)2008,JPO&INPIT
