Description

Technical Field

[0001] This invention belongs to the fields of optical imaging technology and intelligent electronic equipment technology, and specifically relates to a mirror optical information direct acquisition imaging device and method without a camera lens. Background Technology

[0002] With the development of smart home technology and commercial imaging technology, mirror imaging devices such as makeup mirrors, fitness mirrors, and commercial fitting mirrors have been widely used. Currently, most mirror imaging devices on the market adopt a "semi-reflective mirror + built-in camera lens" technical solution: that is, a camera module is installed behind the mirror, and the camera lens takes pictures of people / objects in front of the mirror, and then displays the captured image on a display screen behind the mirror or transmits it to a terminal device.

[0003] However, the aforementioned existing technologies have inherent flaws that cannot be resolved: 1. The image does not match the naked eye's vision, and the reproduction is poor: The camera lens has inherent optical distortion and perspective distortion, and is affected by focus, exposure and white balance parameters. The captured image has a significant deviation from the real mirror image seen by the human eye in a mirror. It cannot achieve 1:1 faithful reproduction and cannot meet the user's core need for recording real images. 2. Poor full-screen reproduction capability, severely limiting application scenarios: Existing mirror imaging devices with lenses generally adopt face-first focusing and algorithm optimization logic, which can only guarantee the clarity of the face area. Non-face content such as clothing, still life, text, and scene environment generally suffer from poor focus, image quality degradation, and severe distortion. They cannot fully reproduce the full-screen content of the mirror reflection and cannot meet the diverse civilian and commercial needs such as clothing recording, scene reproduction, object detail shooting, and motion accuracy recording. 3. Cumbersome operation process and poor user experience: Most existing products require real-time transfer to the mobile phone after a single shot, and cannot be batch stored and centrally managed for transfer. When users take multiple photos, they need to repeatedly transfer them, which is cumbersome and does not conform to daily usage habits. Some products with local storage are set up with logic to automatically overwrite and delete early images, which can easily lead to the loss of important user materials and poses a very high risk of use. 4. Poor appearance integrity and weak adaptability: It is necessary to reserve lens openings on the mirror surface and hide the camera module, which damages the overall appearance of the mirror and makes the visual effect significantly different from ordinary civilian mirrors. It cannot be seamlessly integrated into various scenarios such as home and commercial use. 5. Complex structure, high cost, and high failure rate: It requires multiple components such as a lens, focusing module, image processor, and display screen. The complex structure results in high production, assembly, and maintenance costs. It is also prone to failures such as inaccurate focusing, blurry images, and lens damage, and its service life is limited.

[0004] Currently, lensless imaging technologies have emerged, such as light field imaging and edge computing imaging. However, these technologies directly collect light fields from the target object, requiring complex algorithms to reconstruct the image. They are not integrated with civilian mirror imaging scenarios and cannot achieve the effect of capturing the same image as the mirror reflection. They also lack fully autonomous local image management functions adapted to civilian and commercial needs, thus failing to address all the pain points of traditional mirror imaging devices.

[0005] In summary, existing technologies have consistently failed to break free from the inherent technical route of "imaging through a lens," and cannot simultaneously meet the three core requirements of "fidelity imaging consistent with human vision," "undifferentiated reproduction of the entire image," and "simple and integrated structure." Therefore, a completely new mirror imaging solution is urgently needed to completely eliminate the camera lens and fundamentally solve all the shortcomings of existing technologies. Summary of the Invention

[0006] I. Technical problems to be solved The purpose of this invention is to overcome the shortcomings of the prior art and provide a lensless mirror optical information direct acquisition imaging device and method. This invention completely abandons the traditional mirror imaging equipment's reliance on camera lens shooting, and solves the problems of inconsistency between the imaging and the naked eye's vision, poor full-screen reproduction capability, cumbersome operation, easy loss of important materials due to automatic deletion, poor appearance integrity, and complex structure and high cost. It achieves non-photographic full-screen in-situ extraction of mirror optical information, 1:1 high-fidelity imaging, batch local storage, and fully user-autonomous image management.

[0007] II. Technical Solution To achieve the above objectives, the present invention adopts the following technical solution: (a) A lensless mirror optical information direct acquisition imaging device It includes a mirror surface layer, an optical information extraction layer, and a photoelectric conversion and transmission layer that are stacked and seamlessly bonded together from the outside to the inside; The mirror surface is an optical reflector used to reflect incident light to form a full-screen mirror image visible to the human eye, while allowing some incident light to pass through to the optical information extraction layer. The optical information extraction layer is a lensless optical transmission structure. Its acquisition range completely overlaps with the effective reflection area of ​​the mirror surface. It is used to collect the full-screen optical information transmitted from the mirror surface without discrimination, and to transmit the optical information in parallel to the photoelectric conversion and transmission layer without focusing or refraction. The entire process does not rely on the camera lens for imaging. The photoelectric conversion and transmission layer is used to convert the received full-screen optical information into a complete digital image signal, and to realize the local storage of digital images and transmission to external terminals.

[0008] Furthermore, the surface of the mirror is made of semi-reflective and semi-transparent optical glass, which has a visible light reflectance of 85%-95% and a visible light transmittance of 5%-15%. The surface of the mirror has no camera openings or lens mounting positions, and its appearance is completely consistent with that of ordinary civilian mirrors.

[0009] Furthermore, the optical information extraction layer is a fiber optic microarray plate, which consists of several parallel and equidistantly arranged single-mode optical fibers. The incident end of each optical fiber is bonded to the back of the mirror surface, and the emitting end is bonded to the photoelectric conversion and transmission layer. This is used to transmit the optical information of the corresponding point on the mirror surface to the photoelectric conversion and transmission layer without distortion. The fiber optic microarray plate has a fiber density ≥300dpi, a single optical fiber diameter ≤10μm, an acquisition resolution ≥8K, and no gaps or relative displacements between the bonding surface with the mirror surface, and no acquisition blind spots.

[0010] Furthermore, the optical information extraction layer is a distributed light field sensing array, which is an ultra-thin planar photosensitive material array that is directly attached to the back of the mirror surface. It is used to collect the full-screen spatial distribution, light intensity, and phase information of the transmitted light from the mirror surface in situ, and can obtain complete full-screen optical information without lens focusing.

[0011] Furthermore, the photoelectric conversion and transmission layer includes a planar photosensitive chip, a main control unit, a wireless communication module, and a local solid-state storage module; The photosensitive surface of the planar photosensitive chip is completely attached to the output end of the optical information extraction layer, and the photosensitive range is completely matched with the acquisition range of the optical information extraction layer, which is used to convert the optical information of the whole picture into electrical signals without difference. The main control unit is electrically connected to the planar photosensitive chip and is used to process the electrical signal into a standard complete digital image, ensuring that the digital image is completely consistent with the full-screen mirror image formed by the mirror surface that is visible to the human eye. The wireless communication module is electrically connected to the main control unit and is used to wirelessly transmit digital images to external terminals such as mobile phones and tablets. The local solid-state storage module is electrically connected to the main control unit and is used for local batch storage of the generated complete digital images, with a capacity of ≥32GB, capable of storing ≥10,000 high-definition digital images.

[0012] Furthermore, the planar photosensitive chip is a large-area CMOS / CCD bare chip without a lens, and its resolution matches the acquisition resolution of the optical information extraction layer. It can complete the photoelectric conversion of the entire image without the need for a focusing lens, and there is no local image quality degradation.

[0013] Furthermore, the main control unit has built-in album management firmware, which supports sorting, naming, and marking locally stored digital images by shooting time. It also supports manual deletion, retention, and wireless transmission of single or batch digital images, with operation logic completely consistent with the native album of the mobile terminal. When the local storage space is full, it automatically stops storing new images and pushes a storage space shortage prompt through the paired external terminal. It does not perform any automatic deletion operations, and the deletion permission for all images belongs solely to the user.

[0014] Furthermore, the main control unit has a built-in human body sensing module, which is used to automatically trigger the optical information acquisition and image generation process when a human body is detected in front of the mirror; it also includes a packaging shell, which is set on the outside of the photoelectric conversion and transmission layer and sealed to the edge of the mirror surface layer, completely enclosing the optical information extraction layer and the photoelectric conversion and transmission layer inside, forming an integrated structure with an appearance completely consistent with an ordinary mirror.

[0015] (II) A lensless method for direct acquisition of mirror optical information imaging Based on the above-mentioned device, the following steps are included: S1 After the light shines on the person / object / scene in front of the mirror, it is reflected to the surface of the mirror. The surface of the mirror reflects most of the light to the human eye, forming a full-screen mirror content that is consistent with human vision, while a small part of the light is transmitted to the optical information extraction layer. The S2 optical information extraction layer performs indiscriminate in-situ point-by-point acquisition of the full-screen optical information transmitted without focusing, refraction, or local acquisition priority differences, and transmits the complete optical information to the photoelectric conversion and transmission layer without passing through the camera lens to capture the image. The S3 photoelectric conversion and transmission layer converts the received full-screen optical information into electrical signals and processes it into a complete standard digital image that is completely consistent with the mirrored content, with all areas of the full screen having completely consistent clarity and fidelity. The digital images generated by the S4 are automatically stored in the local solid-state storage module and archived by shooting time through the album management firmware, without the need for real-time transmission to an external terminal; S5 When the local storage space is full, the device automatically stops storing new images and pushes a message to the user's paired external terminal indicating that the storage space is insufficient, without performing any automatic deletion operation; After connecting the S6 device wirelessly via an external terminal, users can independently view and manage locally stored digital images, manually select to delete, retain, or transfer images to the external terminal in single or batch mode, thus completing the saving and management of images.

[0016] Furthermore, in step S2, when the optical information extraction layer uses a fiber microarray plate for acquisition, the optical information of the corresponding point on the mirror surface is transmitted to the photoelectric conversion and transmission layer in parallel without distortion through a single-mode optical fiber. There is no focusing, no refraction, and no optical loss during the transmission process.

[0017] Furthermore, in step S3, the main control unit performs mirror correction on the generated digital image to ensure that the final digital image is a 1:1 perfect match with the full-screen mirror content seen by the user's naked eye on the mirror surface, with no optical distortion and no perspective deviation.

[0018] Furthermore, before step S1, there is also a human body sensing triggering step: the human body sensing module detects the human body in front of the mirror. When a valid human body signal is detected, the device is automatically woken up and the imaging process of steps S1-S6 is started; when no human body signal is detected, the device is in a sleep low-power state. Beneficial effects

[0019] Compared with the prior art, the present invention has the following outstanding substantive features and significant progress: 1. Completely overturns the traditional mirror imaging technology route and achieves non-photographic high-fidelity imaging: This invention completely abandons the inherent logic of "camera lens imaging", directly reads the same optical information formed by mirror reflection and enters the human eye, without lens distortion, perspective deviation, or focus problems. The generated image is a 1:1 perfect match with the image seen by the human eye in the mirror, fundamentally solving the core pain point of the inconsistency between the image captured by the traditional lens and the vision of the naked eye, and opening up a brand-new civilian mirror imaging technology route; 2. Achieves seamless full-screen reproduction, significantly expanding application scenarios: This invention adopts a full-area acquisition scheme that perfectly matches the effective area of ​​the mirror, enabling seamless acquisition and reproduction of all visible content reflected in the mirror, such as portraits, clothing, still life, text, and scenes. There are no differences in acquisition priority, and the clarity and reproduction of all areas of the entire screen are completely consistent. This completely solves the pain point of traditional devices where "faces are clear, but non-face content suffers from image quality degradation." It can not only meet the needs of home beauty, but also adapt to diverse scenarios such as clothing, fitness and dance, commercial retail, medical aesthetic testing, and industrial reflective surface inspection, making it highly practical and adaptable. 3. A fully user-controlled image management system with zero risk of image loss: This invention features a large-capacity local storage module capable of batch storing tens of thousands of high-definition images, eliminating the need for users to transfer images one by one to their phones after shooting, completely solving the pain point of cumbersome single-image transfer operations in traditional devices; the accompanying album management firmware operates with logic completely consistent with the user's familiar native phone album, resulting in low learning costs and no need to change user habits; at the same time, it adopts a protection mechanism that only prompts when the limit is reached, absolutely preventing the automatic deletion of any stored images, with all deletion permissions entirely belonging to the user, completely eliminating the risk of accidental deletion of important materials, and making its security far superior to similar products; 4. Integrated structural design, strong appearance integrity, and wide adaptability: The present invention is an integrated mirror structure with three layers, without any exposed electronic components or openings. Its appearance is completely consistent with ordinary civilian mirrors. It can directly replace ordinary civilian mirrors and seamlessly integrate into multiple scenarios such as home, commercial and industrial settings without changing the user's usage habits. 5. Simple structure, strong stability, and controllable cost: This invention eliminates complex components such as lenses, focusing modules, and displays, resulting in a simple overall structure, low production and assembly difficulty, low failure rate, long service life, and mass production cost that is far lower than traditional mirror imaging devices with lenses, making it extremely valuable for mass production and commercial promotion. 6. The method claims further expand the scope of protection and enhance the strength of rights protection: This invention not only protects the device structure but also the corresponding imaging method, covering infringements across the entire industry chain. Whether it is the manufacturer of the device or the merchant using the method to provide imaging services, they are all within the scope of protection. The commercial value and the strength of rights protection are far greater than those of single device protection. Attached Figure Description

Detailed Implementation

[0021] The present invention will now be described in further detail and in complete detail with reference to specific embodiments and accompanying drawings. The specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of protection of the present invention. Implementation Case 1

[0022] This implementation provides a mirror-based optical information direct acquisition imaging device without a camera lens. It is a desktop makeup mirror with overall dimensions of 300mm×400mm×22mm and an appearance completely identical to a regular makeup mirror.

[0023] This device includes a mirror surface layer, an optical information extraction layer, a photoelectric conversion and transmission layer, and a packaging shell, which are stacked and seamlessly bonded together from the outside to the inside. 1. Mirror surface: Made of optical-grade semi-reflective and semi-transparent tempered glass, measuring 300mm×400mm and 3mm thick, with a visible light reflectance of 90% and a visible light transmittance of 10%; the mirror surface has no openings or grooves, and the front is mirror-polished, making it look exactly the same as an ordinary civilian mirror, with full coverage of the effective reflection area and no blind spots for reflection; 2. Optical Information Extraction Layer: A fiber optic microarray plate is used, with dimensions perfectly matching the mirror surface and a thickness of 5mm. The fiber optic microarray plate consists of parallel, equidistantly arranged single-mode optical fibers with a fiber density of 400dpi and a single fiber diameter of 8μm, achieving a 12K acquisition resolution, completely covering the visual resolution limit of the human eye. The front of the fiber optic microarray plate is seamlessly bonded to the back of the mirror surface using optical-grade transparent adhesive, with no relative displacement. The acquisition range 100% overlaps with the effective reflection area of ​​the mirror surface, providing unbiased coverage of the entire mirror surface without any blind spots. Each optical fiber corresponds to a fixed point on the mirror surface, achieving distortion-free parallel transmission of optical information across the entire image, eliminating local acquisition priority differences. 3. Photoelectric conversion and transmission layer: including planar CMOS photosensitive chip, main control unit, WiFi / Bluetooth dual-mode communication module, 32GB local solid-state storage module, and lithium battery; ◦ Planar CMOS image sensor: It adopts a large-area lensless bare chip with a resolution of 12K. The size of the photosensitive surface is perfectly matched with the back of the fiber microarray plate. It is bonded to the fiber microarray plate without gaps through optical adhesive. It does not require any focusing lens. It can convert the optical information of the whole picture transmitted by the fiber into electrical signals without difference. The conversion accuracy of all areas of the whole picture is completely consistent, and there is no local image quality degradation. ◦ Main control unit: Adopting the ESP32-S3 main control chip, which is electrically connected to the CMOS image sensor chip, and has built-in image preprocessing firmware, it can process electrical signals into standard complete digital images in JPG / PNG format, and at the same time perform mirror correction on the image to ensure that the final generated digital image is a 1:1 perfect match with the full-screen mirror content seen by the user's naked eye on the mirror surface, whether it is a portrait, clothing, still life or background environment, there is no distortion or loss of image quality; ◦ WiFi / Bluetooth dual-mode communication module: electrically connected to the main control unit, supporting Bluetooth 5.0 and WiFi 6 protocols, which can wirelessly transmit the generated digital images to the user's mobile phone, tablet and other terminal devices; ◦ 32GB local solid-state storage module: It adopts an embedded eMMC solid-state storage chip, which is integrated on the same circuit board as the main control unit and electrically connected to the main control unit. It can store ≥12,000 12K high-definition full-screen digital images; the generated digital images are automatically sorted and stored in this module according to the shooting time, without the need to be transferred to the mobile phone in real time. ◦ Lithium battery: It uses a 5000mAh polymer lithium battery to power the entire device, eliminating the need for an external power cord and making it suitable for desktop and mobile use scenarios; 4. Encapsulation shell: The shell is made of ABS plastic and its size matches the surface of the mirror. It is located on the outside of the photoelectric conversion and transmission layer and is sealed to the edge of the mirror surface. The optical information extraction layer and the photoelectric conversion and transmission layer are completely enclosed inside, forming an integrated mirror structure. No electronic components are visible from the outside.

[0024] Furthermore, the main control unit has a built-in infrared human body sensing module. The infrared sensing window is hidden on the side of the packaged shell. When a human body is detected within 30cm-100cm in front of the mirror, the device is automatically woken up, triggering the optical information acquisition and image generation process without the need for manual operation by the user.

[0025] Furthermore, the main control unit has built-in album management firmware, which can achieve the following functions: 1. Automatic archiving: Automatically sorts and names local stored full-screen digital images by shooting time, generating a visual album list consistent with the phone's native album, with the most recently shot images at the top for easy searching by users; 2. Favorites Tagging: Allows users to tag important images to their favorites. Taggled images will be added to a separate favorites album, making it easy for users to quickly locate important content and avoid accidental deletion; 3. Fully autonomous batch management: After the user connects to the device via Bluetooth / WiFi pairing with their mobile phone, they can view all the full-screen images stored locally in real time on their mobile phone. The operation logic is completely consistent with the phone's native photo album. Images can be selected individually or in batches for manual deletion, collection, and batch transfer to the phone. There are no automatic deletion or overwriting operations. All deletion actions must be initiated manually by the user. The device does not have any permission to automatically delete images. 4. Full Storage Protection: When the local storage space is full, the device will automatically stop storing new images and push a "Storage space is insufficient, please clear it before shooting" prompt to the paired mobile phone. It will never delete any stored images and completely eliminate the risk of accidentally deleting important user materials. 5. Access Control: Only mobile devices that have been paired with the user can access and manage the local photo album. Devices without pairing authorization cannot view, modify, or delete any images.

[0026] The imaging method in this embodiment 1 includes the following steps: S0 Human body sensing trigger: The infrared human body sensing module detects a human body in front of the mirror. When a valid human body signal within the range of 30cm-100cm is detected, the device is automatically woken up and the subsequent imaging process is started; when no human body signal is detected, the device is in a sleep low power state. When ambient light shines on the user, surrounding objects, and background environment in front of the mirror, it is reflected onto the mirror surface. The mirror surface reflects 90% of the light back to the user's eyes, forming a complete full-screen mirror content that is visible to the user, including the portrait, clothing, surrounding objects, and background environment; at the same time, 10% of the light is transmitted to the fiber optic microarray panel on the back. The S2 fiber microarray board uses tens of thousands of parallel single-mode optical fibers to collect the optical information of the entire screen without discrimination in situ point by point. Each fiber corresponds to a fixed point on the mirror surface, and the light intensity and color information of that point are transmitted in parallel to the CMOS photosensitive chip on the back without focusing, refraction, or distortion. The entire process does not pass through any camera lens, there is no shooting action, and there is no difference in local acquisition priority. The S3 CMOS image sensor converts the received full-screen optical information into electrical signals and transmits them to the main control unit. The main control unit processes the electrical signals into a standard complete digital image and performs mirror correction to ensure that the digital image is a 1:1 match with the full-screen mirror content seen by the user's naked eye. The clarity and fidelity of all areas of the full screen are completely consistent, with no local image quality degradation. The high-definition full-screen digital images generated by the S4 are automatically sorted by shooting time and stored in the local 32GB solid-state storage module. The archive is completed through the album management firmware, without the need for real-time connection to the mobile phone for transfer. When the local storage space is full, the S5 device automatically stops capturing and storing new images and pushes a notification to the user's paired mobile phone that the storage space is insufficient, without performing any automatic deletion operation; When S6 users need to view, export, or clean up photos, they can connect the device via Bluetooth / WiFi pairing with their phone to view all full-screen images in the local album on their phone. They can then manually select to delete single or batch photos, save them, or transfer them to their phone to complete the saving and management of photos. Implementation Case 2

[0027] The only difference between this implementation case 2 and implementation case 1 is: The optical information extraction layer adopts a distributed light field sensing array, specifically an ultra-thin graphene-based planar photosensitive sensing array with a thickness of only 0.5mm, which is directly attached to the back of the mirror surface without the need for optical fiber transmission. The distributed light field sensing array has a collection resolution of 16K, and the collection range completely overlaps with the effective reflection area of ​​the mirror surface. It can collect the full-screen spatial distribution, light intensity, and phase information of the transmitted light from the mirror surface in situ. Without the need for lens focusing, it can directly obtain the complete full-screen mirror optical information and transmit it to the CMOS photosensitive chip on the back, further simplifying the device structure, reducing the thickness, and making it suitable for dressing mirrors, wall-mounted mirrors, and large-size commercial store scenarios. The local solid-state storage module has been expanded to 64GB, which can store ≥25,000 16K high-definition full-screen digital images, meeting the needs of large-size, high-frequency shooting and multi-scenario use.

[0028] The remaining structure, working principle, full-screen acquisition logic, album management logic, and imaging method steps are completely consistent with Implementation Case 1. Implementation Case 3

[0029] This implementation case 3 is a commercial application scenario, providing a wall-mounted commercial fitting mirror device with an overall size of 1800mm×800mm×30mm, suitable for commercial scenarios such as clothing stores, gyms, and medical aesthetic institutions.

[0030] The core stacked structure of this device is exactly the same as that in Implementation Case 1, with the only difference being: The mirror surface uses a large-size semi-reflective and semi-transparent optical glass of 1800mm×800mm, with a visible light reflectance of 92% and a visible light transmittance of 8%, which is suitable for full-body imaging needs. The optical information extraction layer uses a spliced ​​fiber microarray plate. After splicing, the size is perfectly matched with the mirror surface. The fiber density is 300dpi and the acquisition resolution is 8K. It can capture full-screen content such as full-body clothing, body movements, and store environment without difference. The local solid-state storage module of the photoelectric conversion and transmission layer has been expanded to 128GB, which can store ≥50,000 high-definition full-screen images, adapting to the needs of high-frequency commercial shooting; the main control unit is equipped with additional commercial management firmware, which supports the classification and archiving of images by customer number and shooting time, and supports batch export to store management terminal. The encapsulated shell uses a metal frame, which can be seamlessly installed on the wall, and its appearance is completely consistent with ordinary commercial full-length mirrors.

[0031] The imaging method in Case 3 of this implementation is the same as that in Case 1, which can meet commercial needs such as clothing store dressing records, gym movement standard records, and pre- and post-operative comparison records of medical aesthetic institutions. The whole picture is reproduced without difference, without distortion, and without image quality degradation.

The digital images generated by the S4 are automatically stored in the local solid-state storage module and archived by shooting time through the album management firmware, without the need for real-time transmission to an external terminal; S5 When the local storage space is full, the device automatically stops storing new images and pushes a message to the user's paired external terminal indicating that the storage space is insufficient, without performing any automatic deletion operation; After connecting the S6 device wirelessly via an external terminal, users can independently view and manage locally stored digital images, manually select to delete, retain, or transfer images to the external terminal in single or batch mode, thus completing the saving and management of images.

9. The lensless mirror optical information direct acquisition imaging method according to claim 8, characterized in that, In step S2, when the optical information extraction layer uses a fiber microarray plate for acquisition, the optical information of the corresponding point on the mirror surface is transmitted to the photoelectric conversion and transmission layer without distortion through a single-mode optical fiber. There is no focusing, no refraction, and no optical loss during the transmission process.

10. The lensless mirror optical information direct acquisition imaging method according to claim 8, characterized in that, In step S3, the main control unit performs mirror correction on the generated digital image to ensure that the final digital image is a 1:1 perfect match with the full-screen mirror content seen by the user's naked eye on the mirror surface, with no optical distortion and no perspective deviation.

11. The lensless mirror optical information direct acquisition imaging method according to claim 8, characterized in that, Before step S1, there is also a human body sensing triggering step: the human body sensing module detects the human body in front of the mirror. When a valid human body signal is detected, the device is automatically woken up and the imaging process of steps S1-S6 is started; when no human body signal is detected, the device is in a sleep low power state.
