  • Publication number: 20210149048
    Abstract: A distance measuring device 1 includes a light emitting unit 11 that irradiates a subject with irradiation light, a light receiving unit 12 that receives reflected light from the subject, a distance calculating unit 14 that calculates a distance to the subject from an output signal of the light receiving unit, and an image processing unit 15 that generates a distance image of the subject from the calculated distance. The image processing unit 15 executes image processing within a period when the light emitting unit 11 stops the light emission and stops the image processing during a period when the light emitting unit 11 emits the light. When the image processing unit 15 stops the image processing, a clock frequency of an integrated circuit constituting the image processing unit 15 is further reduced as compared with an image processing time.

  • Publication number: 20200011972
    Abstract: A distance measurement device 1 has a light emitting unit 11, a light receiving unit 12, and a distance calculation unit 13, and outputs distance data for each pixel position to the subject. A saturation detection unit 14 detects that the light reception level in the light receiving unit 12 is saturated. In a case in which the saturation is detected, an interpolation processing unit 15 performs an interpolation process using the distance data of a non-saturation region close to a saturation region on the distance data of the saturation region among the distance data output from the distance calculation unit 13. In the interpolation process, the distance data is replaced with the distance data of one pixel of the non-saturation region, or linear interpolation or curve interpolation is performed using the distance data of a plurality of pixels.

  • Patent number: 8890963
    Abstract: The present invention evaluates the quality of an image shot by a terminal device in a state closer to that seen with the eye. A computer evaluates the quality of an image obtained by shooting a photographic subject including a periodic pattern that fluctuates periodically in one direction. A Fourier transform unit accomplishes a two-dimensional Fourier transform on the image to obtain two-dimensional spatial frequency spectrum components. An analysis unit analyzes the resolution of the image on the basis of spectrum components of spatial frequencies included in the periodic pattern, among the two-dimensional spatial frequency spectrum components obtained by the Fourier transform unit, and analyzes the deterioration of the image on the basis of spectrum components other than these.

  • Patent number: 8780266
    Abstract: Image deterioration when image data containing scanning lines of the previous and next fields mixed together by video editing is displayed is prevented. An inter-field scanning line interpolating unit superimposes scanning line data of the previous and next fields of interlacing image data in a video stream input from a tuner or a memory card to perform inter-field scanning line interpolation, and generates progressive image data corresponding to that video stream. An IP-conversion selection signal indicating a determination result whether or not the reliability of the video stream meets a predetermined level is input into a back-end from a CPU. A selector refers to the IP-conversion selection signal, and when the CPU determines that the reliability of the video stream is lower than the predetermined level, image data having undergone interpolation by the inter-field scanning line interpolating unit is selected as an image to be displayed.

  • Publication number: 20140118577
    Abstract: A mobile phone (101) includes a reader (110) for generating readout information from sensor information generated by an imaging sensor (105). The reader (110) can read out sensor information in different readout modes: a pixel addition mode; and a cutout mode. A readout mode is selected by a mode selector (111) on the basis of a zoom factor obtained on the basis of an instruction by a user. When the readout mode selected by the mode selector (111) requires a change of the readout mode, a switching image generator (125) generates switching image information, and a pre-set switching image is displayed on a display (103), until image information corresponding to the readout mode after the change is generated.
