  • Patent number: 9405406
    Abstract: An image pickup device capable of stably detecting an object irrespective of use conditions while reducing manufacturing costs is provided. When illumination light from a backlight is emitted to a proximity object from an I/O display panel, an electric charge is accumulated in image pickup pixels in accordance with total light amount, including reflected light originating from the backlight and external environment light. Moreover, when the illumination light is not emitted, a discharging electric charge is released from the image pickup pixels in accordance with the amount of environment light. Thereby, an environment light component is subtracted from an image pickup signal obtained from each of the image pickup pixels, so object information about the proximity object is obtained without influence of the environment light. Moreover, in a light reception drive circuit, fewer frame memories for producing a picked-up image from the image pickup signal are necessary.

  • Patent number: 9063613
    Abstract: An image pickup device capable of stably detecting an object irrespective of use conditions while reducing manufacturing costs is provided. When illumination light from a backlight 15 is emitted to a proximity object from an I/O display panel 20, an electric charge for charging is accumulated in each of image pickup pixels 33 in accordance with total light amount as a summation of reflected light Lon originating from the illumination light and environment light (outside light) L0. Moreover, when the above-described illumination light is not emitted, an electric charge for discharging is released from each of the image pickup pixels 33 in accordance with light amount of the environment light L0. Thereby, a component by the environment light L0 is subtracted in an image pickup signal obtained from each of the image pickup pixels 33, so object information about the proximity object is obtainable without influence of the environment light L0.

  • Patent number: 8836670
    Abstract: An image processing apparatus which is allowed to achieve a higher speed of a labeling process than ever before is provided. Sequential scanning is performed on pixels in a picked-up image represented by binarized data Din. Moreover, during the sequential scanning, while label information representing an identification number for each connected region in the picked-up image is, as occasion arises, allocated to a target pixel based on values of pixel data of the target pixel and neighboring pixels thereof, additional information (position information and area information) for each connected region corresponding to each label information is updated as occasion arises. Thereby the label information, the position information and the area information about the whole picked-up image are obtained by one sequential scanning process.
