The present invention presents highly useful information while emphasizing the sense of perspective of a route guidance image. According to the present invention, a processor displays a route guidance image 200 on a head-up display device 20 such that the width Wn of a nearby region of the route guidance image 200 in the left-right direction is longer than the width Wf of a faraway region in the left-right direction. When increasing the scale of the route guidance image 200, the processor increases the ratio (Wf/Wn) of the faraway width Wf to the nearby width Wn.

Provided is a drive assist apparatus visually notifying a driver of information regarding a gradient of a road. A drive assist apparatus includes processing circuitry. The processing circuitry is to acquire gradient information of a road in which gradient illusion is estimated to occur in a driver of a vehicle. The processing circuitry is to perform control on an irradiation apparatus provided to the vehicle so that the irradiation apparatus projects a gradient recognition pattern on a target object or on a projection surface provided in front of a driver seat of the vehicle to display the gradient recognition pattern in overlapped fashion with the target object. The target object is located in front of the vehicle and extends along the road. The gradient recognition pattern includes at least one graphic based on the gradient information of the road and disposed along the extension direction of the target object.

A holographic display system provides a maximum intensity value of an intermediate image to decrease a graphics speckle noise. The system includes an SLM having a display with a hologram generating unit and a plurality of pixels for modulating a beam of coherent light. The system further includes a beam splitter for splitting the beam into an object beam and an intermediate image beam that is associated with an intermediate image having the noise. The system further includes a camera for capturing the intermediate image, in response to the camera receiving the intermediate image beam. The system further includes a computer having a processor and a CRM. The processor is programmed to generate an actuation signal associated with a corrective holographic phase shift to decrease the noise. The SLM modifies in real-time a holographic phase of the beam per pixel, in response to the SLM receiving the actuation signal.

A method is provided for visualizing optical information in the central field of vision of a driver in such a way that a display (5) in the form of a virtual image is superimposed on a real traffic environment. A position of the display (5) is dynamically variable as a function of a vehicle speed, a steering angle, and a road type. Thus a horizontal and/or vertical spread of a display range (8) between a first maximum value (9) and a second maximum value (10) within which the display (5) can be displayed is varied as a function of speed, steering angle and roadway type.

This application discloses a display method, an apparatus, and a system, so that an electronic apparatus can display prompt information of a target object at a first moment based on an obtained predicted position of the target object at the first moment and a measurement position before the first moment. This effectively reduces output jitter and improves user experience.

A head-up display system includes an eye-box having a first and second dimension, an image projector including a picture generating unit and an optical system, and a movement assembly. The picture generating unit includes a spatial light modulator arranged to spatially modulate light in accordance with a hologram. The optical system relays the spatially modulated light to an optical combiner. The movement assembly moves at least a portion of the image projector rectilinearly between a plurality of positions such that at least one component of the picture generating unit is moved together with the optical system. Spatially modulated light relayed to the optical combiner forms a virtual image viewable from a sub-eye-box having a position in the first dimension being dependent on the position of the at least a portion of the image projector. The eye-box is the sum of the sub-eye-boxes associated with each of the plurality of positions.

A set of training images are input into a neural network that outputs a pixel-wise phase matrix identifying pixels in the training images. Based on the pixel-wise phase matrix, a spatial light modulator (SLM) is actuated to output, onto a vehicle windshield, an augmented reality (AR) image including a plurality of sub-images each output in one of a plurality of focal planes. Each training image corresponds to one respective sub-image. A feedback image of the AR image is obtained via an image sensor. An offset is determined based on comparing the training images to the feedback image. Parameters of a loss function are updated based on the offset, and the updated parameters are provided to the neural network to obtain an updated offset.

An automated driving unit implements an automated driving of a vehicle by implementing a present operation and a subsequent operation in order. The subsequent operation is an operation to be implemented subsequently to the present operation during the automated driving. A determining unit determines the subsequent operation of the vehicle. An imaging unit creates an image relevant to the subsequent operation according to information on the subsequent operation. A display unit indicates the image relevant to the subsequent operation while the automated driving unit implements the present operation.

The image processing method includes generating an image based on viewpoint information of a user; rendering the image based on information about what is in front of the user; and outputting the rendered image using an optical element.

A projection unit for a field-of-vision display device for a vehicle includes an imaging unit for generating a light beam bundle having a display content; a mirror which is disposed in the beam path of the light beam bundle and has a first adjustment apparatus configured to tilt the mirror for adjustment to different eye-box positions of different users; and a second adjustment apparatus configured to tilt the imaging unit or an additional optical component such that image orientation is maintained. The projection unit is configured to generate a virtual display image in a virtual image plane in the field of vision of the user by outputting the light beam bundle toward a reflective pane, by which the light beam bundle is reflected to the eye-box of the user. The tilt is configured such that the virtual image plane has the same predefined orientation for the different eye-box positions.
