  • Patent number: 10986264
    Abstract: The present technology relates to an image processing device, an image processing method, an image sensor, an information processing device, and a program that facilitate cancellation of a locked state. An image processing device includes: a detection unit that detects a predetermined state, using data from a plurality of sensors; and an imaging unit that captures an image of a predetermined object, in a case where the predetermined state is detected by the detection unit. The image processing device further includes a plurality of input interfaces that input the data from the plurality of sensors. When an application processor switches from an activated state to a non-activated state, detection by the detection unit is started. The present technology can be applied to a smartphone, for example.

  • Patent number: 9485440
    Abstract: A signal processing unit; includes: a high-frequency signal determination section configured to determine whether a reference region as a peripheral region of a phase difference pixel is a high-frequency signal region in a specific direction based on a pixel signal output from an image pickup section having the phase difference pixel disposed therein; and a synthetic ratio determination section configured to, when the reference region is determined to be not the high-frequency signal region in the specific direction, determine, using a pixel difference of the reference region, a synthetic ratio of an interpolated value of the phase difference pixel by a gain multiple interpolation technique to an interpolated value of the phase difference pixel by a peripheral pixel interpolation technique.

  • Patent number: 8633937
    Abstract: A memory section provides an input buffer capable of holding image data being a processing target of each processing by an image processing unit, and an output buffer capable of holding image data being a processing result. Through an input section, a user selects a plurality of kinds of processing to be executed by the image processing unit, and an execution sequence of the plurality of kinds of processing. A controller section reserves, based on information selected by a user through the input section, an input buffer and an output buffer for each processing in the memory section, sets an input-output connection relation between the buffers, and notifies, based on the set connection relation, the image processing unit of address information of the input buffer in the memory section and the output buffer for each processing sequentially executed by the image processing unit.
